Vesc acceleration I am using a flipsky 7550 vesc based controller and a 60v self made liion battery. At that price point i expected much more. A ADC: A type of electronic circuit component that converts analog signals to digital signals. When I use the VESC tool I can avoid that little Hi everyone, as I stated a few days ago, I was requesting a boost current feature to allow a short term increase in the maximum motor current, Intended for motors without temperature sensors ( i. Username * Password * Create new account; Request new password; It would be much cleaner to set acceleration limits (both positive and negative). I would like to have some special algorithm of current limitations. If at any time after the conversion you want to switch back, it will be as simple as reinstalling and connecting the old the vesc manufacture recommend to use BLDC mode and set max erpm to 60000, I've configured the rest according to the motor and battery. any help is appreciated! I'm using VESC: Maytech vesc100A v4. has_acceleration_limits: true linear. Dillon. UAVCAN has been added to the firmware allowing to interact with commonly used VESC Project. I also recommend checking that your settings have been written to both sides of the ESC. VESC Tool can be used with the latest VESC compatible hardware and most VESC based hardware of the past. Can be applied to basically any scooter. (Sidenote: VESC is a registered trademark itself) ⚠ DISCLAIMER: The VESC Bible is currently being republished and rewritten to encompass all necessary beginner guides. It is an open-source electronic speed controller originally designed for electric skateboards. The RPM-Current mapping is especially nice for electric vehicle applications where you want to have constant acceleration for a given throttle amount. As my VESC does not successfully test the BC=BLDC mode, but only FOC I cannot test the other one to see a difference. The biggest drawback is the poor thermals at high sustained amps. You simply can't push the motors or VESC or both to their absolute pre-defined temperature limits any more. In consequence the brakes will still work, even if you push your system to a soft power The acceleration and deceleration ramp time adjustment is great for smoothing the response to control input. As you descend a hill, the tail lifts, and as you ascend, the nose lifts. Goo-shtick March 15, 2017, 6:33pm 1. 3-shunt design removes the need for calculation and makes the VESC 6 have a smoother and more linear acceleration when compared to the VESC 4. We are considering using the VESC in future Metroboard models, but the lack of Duty Cycle control with the ability to coast is currently a deal breaker. So even if you’re not trying to go faster, a little acceleration here, a little higher speed up a hill there, will all lead to a faster use of that energy per mile resulting in decreased range. The DRV8323RS have 3 amplifier for low ATR, or Adaptive Terrain Response, is a feature for VESC-based one-wheels designed to adjust a board to changing terrain. tpal. My previous controller had a more pronounced acceleration at startup. However, it can be difficult for many people to understand this technology and how it works, which can prevent some people from taking advantages of the benefits it offers. It’s published in 2016. This calculation and only measuring two of the Add the measurement resistor to the third lead, e. Code to support full-featured Ninebot Max G2 operation using a VESC-based controller and an Arduino Nano ESP32 - TriWrite/VESC-Ninebot-Max-G2 Supports launch boost: if not in thermal management, then allow boost current at low speed to assist acceleration from standstill; G2 BLE to ESC serial protocol is very similar to that for the G30 etc VESC Hardware by Benjamin Vedder is licensed under a Creative Commons Attribution-ShareAlike 4. 5 Volts) means it’s not engaged aka off, whereas a higher voltage (usually The Float Package is a Onewheel-centric replacement for the stock Balance Package found in VESC FW / VESCTool 6. Acceleration Temperature Decrease 15%. I use Vesc-tool and I haven't selected in ADC App -> General tab -> Duty Cycle. + People have upgraded the suspension shocks. Fully programmable (using tools like VESC Tool). The only alternative to electrical energy I can think of is heat. I am building a very fast ride on car for my son. This question is for testing whether or not you are a human visitor and to prevent automated spam submissions. I have managed to recreate this issue several times, with the latest test giving me +75A instead of the -120a it should be giving. Even while reading the data Typically you use two throttles, one on the ADC1 for acceleration and the other one on the ADC2 for regen braking. I didn’t see anything for a brake and acceleration, but I I'm having a hard time adjusting the acceleration ramp on current control. I built an electronic e-bike throttle and connected it to the ADC1 input. false #velocity_rolling_window_size: 10 # Velocity and acceleration limits # Whenever a min_* is unspecified, default to -max_* linear. Cruise Control for dual setups via steering channel connected to the second VESC: Cruise Settings. Marcin 1 W. New batches of the VESC 6 will consider this. Choose Current No Reverse Brake ADC2 for this setup. To make sure my units make sense, I've been using the VESC-tool to look at the tacho and the rpm. I have a 10s4p pack that’s kinda frankenstiened back together because I moved the lcd and had to change the chargeport and on / off switch its a dual 190kv TB motors and 2 vesc x controllers This is my VESC settings:-Absolutt max current 200a-Motor current max 135a-battery current max 98a-battery voltage cutoff start 52v, end 48v-MOSFET temp cutoff start 80c, end 90c-Acceleration temperature decrease 0% (tried 15% )-Duty cycle 96% (i get to 50% on static thrust test) I have tried the following things: VESC FOC motor control uses hall sensors at low speeds (usually we set hall sensor erpm to 2000, aka 4mph) and then switches to sensorless above that speed. My technique is to kind of lean over the handlebar otherwise it Given these cheap brushed 550 motors double their speed going from 12 to 24v, I'm wondering if there is a way to cap voltage (top speed) while not impacting the acceleration. " Why? Look at the origin of VESC developement, skateboards. has_jerk_limits: false linear. 10A). ESK8 Electronics. This comes from the upgraded current measurement design of the V6 compared to the V4. Axle is not as robust as the XR. If I set the sensorless The observer will simply not track a motor well in saturation, and the extra acceleration you get by pushing is that hard is most likely not worth the efficiency loss. Throttle curves: Users can adjust the relationship between throttle input and motor output to achieve desired acceleration and braking characteristics. Onglet Sensors : Cliquez sur apply, et la table se remplit automatiquement avec les bonnes valeurs Sauver la config moteur. Date Added: Task: Link: Status: Done in FW: 2017-09-05: PPM reverse function with double tap. Log in or register to post comments; Fri, 2020-01-24 17:38 Could you share video of motor acceleration with relatively low and high currents, like 3 and 300A ? Top. When I do a load test (variable friction test) I can if started slowly (10-15sec) accelerate up to the max of 95% just as defined. I took some time to make screenshots and ad in explanations. This is useful to still have braking torque left when the components get warm. 2. Off road terrain handling needs more firmware tuning. because leaning forward to compensate acceleration with an skateboard will throw Acceleration is as smooth and quite as can be, BUT top speed is a complete disappointment. [ l_temp_accel_dec ] Vesc Tool describes it thus: Decrease the motor and MOSFET temperature limits by this amount during acceleration. From these basic values other values can be calculated that are essential for the motor operation. We manage to run the Setup and understand the vesc tool more. A low voltage (usually below 0. 8 and 0. BLDC works well, but I get some very nasty RPM spikes at low speed (<1000rpm) mostly when the motor transitions from one direction to the other. For an electric skateboard a strong Timeout Brake is not appropriate, since the rider would not be prepared to a sudden hard braking force. So it's also more efficient. Hit about 90mph, VESC based. Last seen: 11 months 6 days ago . Joined: 2017-08-14 11:48 On the VESC side all input methods just call the same global functions. Dans le menu de droite, cliquez sur le bouton : Write motor configuration VESC Tool>App settings>General Glossary This glossary includes common terms and concepts related to Onewheel and VESC technology. Sometimes the fault occurs during acceleration oder deceleration without any load, then it looks like this: Hey, I'm using an arduino connected to my VESC with UART to rev a BLDC motor, and that works fine. Last seen: 5 months 1 week ago . At first I started inspecting all the hardware and electrical This duty cycle value give me "DRV" errors when I try to start making a big cog on the motor. Now we would like to connect our vesc with an Arduino Uno with UART link. The Solution For Vesc = V - VgRE^2 mgRE W = c) What is the escape speed for a particle projected from the center of Earth? (b) If the particle is dropped from rest at the surface of Earth, wh Use the following as necessary for the acceleration due to gravity, and m. Top. I use the VESC on my ebike with a 12s lithium battery and a 9C 2706 hub motor with hall sensors in FOC mode. But lately, I've been riding on dirt practicing braking I'm having some trouble tuning my VESC 4. Duty cycle current limit Vesc Tool describes it thus: Decrease the motor and MOSFET temperature limits by this amount during acceleration. I'm convinced that this is not my fault but a bug. In my dreams, there would also be jerk limits. the ride still feels like there is a bit of excess forward-backward yo-yo acceleration, but maybe this is inevitable with FOC? I'm not sure. Connect to the vesc with bluetooth (assuming you have a bluetooth module), start realtime data with the little "RT" button on the right, do a short test accelerate, then stop the PID speed control no acceleration This mode is experimental, when you press the throttle then it only activates the Cruise Control and hold the speed. 9 or less means braking is softer than acceleration (tail softer than nose) 1. The VESC-6 Controller has a smoother linear acceleration when compared to the VESC-4. The Original VESC provides excellent performance, customization options, and is compatible with various motor types. I keep reading about a motor controller called a VESC (and various sub versions). Blinks red light, as soon as i let off the throttle it goes away and works properly. 00 and 6. Not sure if this is simple to achieve, but is for sure something that will suit people with devices or machines with 4 wheels If you run two VESC motor controllers on one battery, you need to cut your safe battery limits in half. Something similar could be achieved by decreasing the gain for the current control loop. Link to forum Going VESC typically unlocks higher current draw in general. Offline For my project I'm doing some acceleration calculations wit a VESC connected over UART where I make use of distance and speed. The gain can be configured from BLDC Tool. 31 bldc firmware (VESC) added “Acceleration Temperature Decrease” option. I set Min Voltage (0,85V) and Max Voltage (2,55V). Therefore four different current limits give the maximum flexibility. When riding on pavement I have these values set to 0. Launcher Motor setup wizzard. However, today I managed to throw an ABS Overcurrent fault by flooring the board while going about 1/2 speed and it almost threw me off. I left the VESC powered on and opened the terminal and read the fault codes. Nuccio. Log in or register to post comments . VESC 6: The VESC 6 is the latest iteration of the VESC, and it offers improved features and enhanced performance compared to its predecessors. Use a serial USB adapter to connect the Xiaomi controller as an USB VESC : Launch VESCTool and connect with COM port. Motor is a 48v 600w nominal T9 scooter motor. Having the motor resistance above 150mΩ would actually create a motor crunch at hard acceleration! VESC Project. If I accelerated moderately, then released the control while coasting, then re-engaged acceleration, the motor would suddenly brake instead of accelerating. so by normal Open the VESC Tool software and click 'Auto Connect' Once your FOCBOX has connected, you may get an alert letting you know that you need to update the firmware. The same thing is true for acceleration; setting a higher motor current than battery current means that high acceleration is possible at low to mid speeds, and then the acceleration gradually decreases as the speed increases. Description I am following the steps 'without ADE' from here: https://auto The Onewheel VESC is, in short, a Onewheel from Future Motion Inc where the user has swapped out the stock controller for a third-party one. Math question * 7 + 5 = for acceleration: seconds: W: A: acceleration duration to reach Vmax This can be noted on HW4 where a commanded constant current will give a non-linear acceleration: it will be linear to around 60% of full speed, then it will decrease for a bit up to around 80 % and then it will increase from 80% to 100%. while maintaining a constant acceleration/ramp. has_velocity_limits: true linear. The 13s bike runs 30 battery and 60 motor amps (limitations of the battery and motor). So, what controller are you using? Hi there, I've jus recently done a build using a VESC based ESC but I'm having some occasional troubles with it during use. VESC measures both flux linkage and inductance Added support for HFI to track motor position at 0 speed without sensors. Excellent for high-current loads and precise motor control. when i manually turn my sensored motor around I get about 42 tachometer units per rotation. 1) Instrument the motor with a thermistor and connect it to the VESC for temp compensation 2) Measure motor parameters at a lower voltage Our Favorite Vesc Based ESC: https://geni. MY1020 BLDC 1800W 4500RPM brushless motor (I calculated about 104kv but not able to confirm specs) 48V 13s li-oin 10Ah battery - Might switch to three 4s li-po batteries from RC car to see if I can get more current. Throttle curves: Users can adjust the relationship between throttle input and motor output to achieve desired acceleration and braking characteristics I spent hours on the superflux and got nowhere with hfi using vesc or my code. VESC tool is rad, but it has a steep learning curve for new users doing setup. they also tend to be around $200 The VESC has all the hardware necessary to pulse the stator with current, measure the phase current/voltage ramp characteristics, and spit out the current at which the stator saturates. x. What kind of datas can be send to the PID integrated in the vesc ? Acceleration ? Current ? And in which format ? but I have a little problem with the throttle response and the acceleration. Last seen: 1 year 3 months ago have done the first test runs on a 4kw kick VESC Project. So I would either use current control, or duty cycle with the positive ramping time in the PPM page set to something reasonably high to limit the acceleration I'm using a sensored 200KV motor for my project, controlling the RPM over UART with the VESC in FOC mode. Result is an uneven acceleration. Increasing the sampling rate wouldn't make this any better imho. Sensor mode: Hydrid with ERPM set to 1400 You can test by setting duty cycle in VESC tool to 0. I am turning a flywheel with the motor to provide some resistance and also measure the motor's torque. Separate limits for acceleration and braking current. Again, you can experiment with the parameters I mentioned if acceleration speed and temp noise . Math question * 5 + 15 = for acceleration: seconds: W: A: acceleration duration to reach Vmax First thank you for your quick answer. I’m also occasionally discovering new ways my skateboard is trying to kill me. It will be updated on a regular basis. It uses a microcontroller to interpret input signals from a remote control or other devices and adjusts motor parameters like torque, acceleration, and braking. If the VESC is in an insulated bag without air circulation getting the heat away can be difficult and the temperature will eventually rise. 8 Hz current oscillation on level ground with FOC at max speed. At first I thought it was a torque issue, so I doubled the max amp ratings on You’ll also find a new IMU chip fitted - featuring a 9 axis gyroscope and accelerometer, the VESC 6MKVI knows its 3D orientation in space, 3 axis acceleration values. I just got most/everything working but on a bench test, it seems like the throttle response is very slow on the vesc. Log in or register to post comments; Tue, 2018-03-20 04:30 #3. With lower profile and drag you could go 100kph with that power. Fixed CAN-bug in VESC Remote. Discuss this question LIVE. VESC Project. Offline . I always thought my previous BLDC controller was doing ok . my comment from above. I can feel solid acceleration until it hits a plateau at 20,000 ERPM. 12. Motor stuttering and making loud noises when under 20 km/h, it gets worse when under load. I had trouble getting FOC mode to work, mostly because the acceleration/torque were too high and my speed loops would not close. During the initial setup of a VESC Tool is the primary software used to configure and monitor VESC controllers. If you've always wondered what many of the settings do in the VESC Tool, here's a video describing at least all the ones relevant for our Onewheel builds00:0 I am controlling the VESC in current mode. I cant get the hall sensors to work, but I dont think they ever worked on my diy meepo board years ago which is where they are from. Supports smooth acceleration, torque control, and braking. I am using the Maker X D75 with a 16S5P 21700 pack. Short term I plan on doing the following. So far it accellerates faster, way carvier and higher speeds than XR. Joined May 12, 2015 It seems that the VESC is highly tunable, and would probably work with just about any motor? I'm thinking of using the ME1616 motor with the 75/300 -- is that possible? The ME1616 is rated 20KW continuous. Username * Password * Create new account; Request new password; CAPTCHA. The advantage of the VESC is the configurability that allows it to be programmed for your specific application. Very impressed with the VESC so far on acceleration and brakes; very smooth, feels very natural, can't wait for the rain to stop so I can wind it up and get some distance runs Thanks Vedder and Marcin! My eBoards Offroad Onda with in deck electronics Dirtsurfer mid-drive conversion MBS Pro 12. Current MIN is the value that is used during braking/regen (storage of energy into the battery). -25A becomes -12. I am giving full brakes and for some reason it decides to give ~50% acceleration. To me. The VESC is not capable of anything other than Regenerative braking. bldc-tool, battery. g. Username * Password * Create new account; Request new password; I am able to control the acceleration and current perfectly fine up until the scooter hits around 30 km/h where it will suddenly accelerate even harder, even though the input hasn't changed. For example, many models feature regenerative braking and the ability to program acceleration curves. Sensorless relies on back EMF from the motor to estimate the motor position. All other Future Motion components will be re-used, including the stock BMS, battery, and wiring harness. Joined: 2020-10-17 20:05 I have two hub motors (qs205 v4 4kw and a qs260 v4 10Kw) running on VESC. #vesc #acceleration #trottinetteelectrique #escooter ». But it still has trouble with high acceleration rates. i did end up finding the option for Current No Reverse Brake Center explained in a youtube video, but heres another question for you: if i used the Current No Reverse Brake Center option and kept my brakes mechanical, wouldnt it consume less battery My VESC 6 produces 0. In addition, acceleration is jerky, one side seems to pulsate and one side VESC using FOC with hall sensors and hub motors needs a little tweaking after using FOC wizard. 3 respectively. cn--Maytech official website. How do i do this? I’m not running sensored By contrast during the acceleration of electric vehicles, one can choose how much motor current to use, with more current generally resulting in more torque, faster The vesc will be calculating output in terms of Q axis currents before transforming back to three phase so you may as well perform your calculations in the way you will code Solve this simple math problem and enter the result. steviebuilt93. 64) and exactly same config on both but one is ok and second one not. Acceleration is 2 times further and there is also a breakdown and a stop. it's designed for high power electric skate boards (some versions supporting 100a continous, 400a peek per motor). Another added benefit of version 6 is that it allows for a higher max current limit, increasing the maximum power of the controller. " BTW, acceleration control mode would be so good if it could be implemented on further versions. You might be able to improve your situation with a better controller. Vidéo TikTok de 🎖️Frechh🎖️ (@frechhtrott) : « Découvrez mon parcours d'entraînement à la trottinette électrique avec des conseils sur l'accélération et les virages. So lets say the first five starts from standstill with full acceleration leads to over currents with the VESCs output shutting down for a moment. I like the feature of picking a desired RPM, but when I get to higher RPMs, I have to manually the only setting I ever use on VESC is 200ms, 80-85% start duty. Skip to main content. Problem I have is at speed 0 and on steep hills. 20. 05 or lower and stopping the wheel with your hand. Joined: 2024-02-19 00:35 . For example, when motor is idle (DUTY CYCLE =0) I would like to have much more current to start motor under load for few seconds , then I can make it lower. But you're right, I have for now just seen 1 fully modded GT2, and without many details. The VESC-4 is built upon a 2-shunt configuration, measuring two of the three leads to the motor and calculating the third. 0. The VESC is located insid a fiber class box, but this box has a forced air cooling so that the heat can move away from the box. History, Furthermore, I've noticed that the throttle response is less aggressive than expected. VESC feels like you are controlling the acceleration itself, until you hit desired speed). 02 and both of them have a really bad behaviour at the end of the Motor Setup Wizard. Peop "You might be able to get up to 100kph on the flat ground with no wind, but the acceleration will be ridiculously slow. However under harsh acceleration or on moderately steep hills the VESCs are cutting out. Torque VESC v4. When you look at the position graph in VESC tool, you should be able to see these six states of the sensors. The VESC gives more acceleration / output for the same amount of input. Home; Powered by the stock XR battery, cheap BMS, Raiden7 vesc and off course fully configurable by the VESC tool. As I have a precontroller to control the VESC (the German ForumsController), I have a good comparison of how exactly 100W of input power feel. Log Study with Quizlet and memorize flashcards containing terms like acceleration, escape velocity, inertia and more. The VESC tool setup wizards were easy to I am new to VESC and respect how versatile this tool and hardware is but am very frustrated. Almost the same, but even at the beginning of acceleration there is a slight slowdown, and then also acceleration and stall. 12 (latest firmware) for optimal performance. See more In FOC mode, I seem to regularly have the motor from the slave triggering absolute over current error. e. There were many of the same code, so I copied the first and last 2 codes in the list below. Reset current integrator when leaving duty cycle control mode. In the VESC tool, go to the the Sampled Data tab and push the T with the bug to trigger a data capture when faults occur. But I can't get the motor to accelerate smoothly with my potentiometer on the arduino. Field weakening on VESC is somewhat crudely implemented but works for In VESC tool, it’s always good practice to read current settings before you do pretty much anything. Students who ask this My trampa vesc 6 mk5 is cutting out during hard acceleration. That is not real traction control, it is just limiting the rate of acceleration. Key parameter is inductance for hfi, tweak it up and down in 10% intervals, you might have to go I have the controller configured with a single throttle that supports both regen and acceleration in the same unit (Spin-y). I'm using Duty Cycle in the ADC Settings and DC settings are all default. The plan is to run motor currents of 120A (possibly 150A) through the VESC during acceleration, and because of that to submerge the VESC in oil with a circulation pump and a heat exchanger on an aluminum part to keep it at a moderately healthy temperature. When i kick and squeeze, its fine. 6 PLUS and flipsky 6374 190kv 3250w motors. 30 (Default) and throttle is on Current mode. The motor specs are 20 poles (2P), motor weight is 3kg. 0 International License. Hey how did you get your controller work in bldg mode ? I'm riding a VESC on a mountainboard, and over wet grass I'm getting a lot of wheelspin when using current control. MTVESC100A V4 based Speed Controller with Heat Sink On & off Switch – Maytech. Benjamin added a new Feature called Acceleration Temperature Decrease. kylerlaird. They ride up to 35 mph, with furious acceleration, two 3 kW motors air-cooled, no problems. For "sport" mode (regulating power and speed), you can use VESC profiles in the app. On the left hand side of the VESC Tool, click on the When I use current control I rarely use full throttle only on occasion when I want to go quick acceleration, but probably only use 1/4-1/2 throttle to get to 30mph speed. These six states indicate discrete positions within an electrical revolution, and those positions are all the controller needs to know to commutate the motor. Thanks to the speed mode of the VESC however the acceleration/braking is linear and very smooth. Arduino Nano - PWM control, Acceleration ramp, timer (60sec) VESC ESC 4. 02 - abs overcurrent I have built a series 8000 w brushless sensorless pre-rotators that all burnt (controller and motor) because my acceleration acceleration is not limited by the current in the mower circuit I have just discovered Vesc project and i am planning to purchase a Vesc 100/250 and I have a couple of questions: I'm not sure if a CBXR with a VESC could be tuned to perform exactly like a GT - there may be some nuances to the two batteries' configurations that may mean you can (for ex. By customizing the acceleration and braking curves of the device you can get, for example, an electric skateboard, to behave For your use case of efoil, current control will change your acceleration, duty cycle will control your speed (but acceleration can be very harsh), PID will act similar to duty cycle. It is known for its higher current-handling capabilities, making it suitable for Here the link to the documentation of VESC-Tool. It does not only allow you to configure your VESC devices and upload the latest firmware – it allows you to generate real time data and find out how to set up your VESC Project. "VESC Tool does not allow uploading firmware to all VESCs on the CAN-bus if they have different hardware versions. I am able to go from 0 - 20000 in about 4 seconds. So you could have a "law compliant" profile you can switch into quickly, which will not only limit speed, but also power and acceleration. Math question * 3 + 2 = Solve this simple math problem and enter the result. I have put same firmware (3. Wed, 2018-04-04 20:18 #1. When it can start, every is ok, acceleration are smooth and quick. Turnigy SK3 ) , to increase performance and acceleration without risking motor overheating during long term increased load, for example climbing up a long hill . Downsides: There are no tire options yet. In the video, see link, the motors make a weird sound (happens twice in the video) and the bike starts vibrating. I have developed vesc 6 derivative using the DRV8323RS chipset. max_velocity: 1 My build has a Flipsky Dual FSESC6. Sensorless ERPM lowered to 500. Cons: Higher cost and steeper learning curve for beginners. motor: Scorpion SII-4035-450KV VESC stands for Vedder Electronic Speed Controller. User login. Mathematically, the escape velocity, Vesc, is defined as where M is the body's mass, R is its radius, and G is the gravitational constant. 30-50A per side is enough to get you moving quickly as the max current is really only used on acceleration or up a large incline. I added 'acceleration' to vesc rpm graph and really see some glitches: thank you for the input vadicus. It is an open-source project that allows users to modify and tweak the ESC’s settings to fit their This is a TODO list for features in VESC Tool and in the VESC firmware. The FETs have more or less the same resistance as on the VESC 4. 12, I noticed one day after turning on my board and hitting the acceleration on my controller, the motor starter wigging out, moving back and forth rapidly with no control . Is it possible to use this data for stability control of RC cars? I would like to detect when the car is doing a wheelie. I was expecting to have more torque than I’d like to handle on this build but it seems rather lacking. x, which itself is a port of the original Balance App we are used to. With 40A of field weakening it can hit 38mph with impressive acceleration. Finally, the braking systems are highly effective. Hi, what is status of the project? I am interested to buy VESC with FOC control at ~ 120V 300A or 75V 500A. I dont get any fault code, when this happens. I reduce it down to 20 and 15 mOm. Thanks a lot for your help After hard acceleration or going uphill fast, power is dropping fast. I havent Accelerating to full throttle or further past the original point of acceleration doesn't disable it and it will continue to hover at this acceleration point until you press the manual brakes and slow it down. Separate limits for motor and battery currents. I'll DM you the link to the Vsett and VESC groups tho, very helpful people and a treasure trove of information there. Hi ladies and gents! I'm working on a 2 wheel drive high power bike conversion (5kW continuous, 10kW peak) and am pricing out components. C’est pas encore parfait mais pour du 60v c’est franchement pas mal ! Vesc 75200 x2 en 60v #trottinetteelectrique #escooter #test #acceleration #vesc. ) get more range out of a CBXR-style battery, but more juice at at one time (and thus more torque) out of a GT-style battery. He does a test of the motor and sets its parameters (Photos 1-2). Hi folks! My VESC 6 has a built-in gyroscope and I can see the orientation of the VESC in my Android app. For the most part, everything works perfectly, however after a while I'm using the VESC Tool as a controller for a motor that is being used to test flexible drive shafts. us/mEOxAU6Today we go over Throttle Curves and how they might help you DIY Electric Skateboard build. Software Installation and Configuration Tutorial. I just selected it in the Mapping tab. Posts: 1 . VESC® Tool is the all new and 100% revised replacement for BLDC-Tool. Then I checked each component and point by point it grew better when I transferred the VESC back into it's place and checking all the sensors/inputs. it is a flipsky vesc mini 4. Last seen: 1 The VESC needs to know the motor resistance, electrical inductance and flux linkage (λ). Log in or register to post comments; Mon, 2020-02-17 08:27 A good controller, like the VESC (open source ESC project), gives you the option to change the way the throttle reacts. 12 hardware. I am very confident the hardware is setup properly. 6 cell and 8 cell lithium battery packs capable of up to 60A draw continuous along with a laboratory power supply. Fortunately they come with hall sensors. Doing anything else would melt or fry the VESC, or the Motor. Log in or register to post comments; Thu, 2022-05-05 19:29 #5. The same thing is true for acceleration; setting a higher motor current than battery current means that high acceleration is possible at low to mid speeds, and then the acceleration gradually decreases as the VESC (Vedder Electronic Speed Controller): VESC is a popular type of ESC known for its versatility and customizability. When I slowly hit the accelerator you can see the motors just stutter, then one starts going, and the other will finally start spinning at max speed. I have been very impressed with the improvements especially regarding the lack of faults compared to the VESC 4. Outrunner sensorless 280kv BLDC Motor. The VESC comes from the controller choice, a Vedder Electric Speed Controller Hi, I’m quite new to handling VESC and I come from an Exway. Log in or register to post comments; Tue, 2022-05-31 15:00 Saved searches Use saved searches to filter your results more quickly Can the VESC brake the motor in any way other than charging the batteries? The kinetic energy has to be converted to some other form or energy. VESC Tool is essential for setting up a VESC board for the first time and calibrating various components. JPG 1534×912 140 KB. I think that this would be a really useful feature for many people who are wanting to find the maximum motor current, and who cannot afford/access the hardware Since I’m new to configuring VESC and didn’t see anything specific about this, i thought i’d start a thread for it for myself and anyone else. Log in or register to post comments; Mon, 2024-02-19 05:34 (Reply to #3) #4. Choose the correct mode in VESC-Tool and you should be good. 6 posts / 0 new . You can define: My scooter has acceleration settings 1-5, 1 and 2 are very nice and gradual, almost like a delay to it but it's a very deep curve of slowness before the torque starts to kick in, even though it still uses a Motor and Vesc dont get hot, just a little bit warm when riding. 6 Plus as VESC along with a MTB kit with 8’’ Pneumatic Tires and Dual Belt-Drive 2 x 2000W 6354 Out-runner Motors. I am using MKS and FlipSky 50A VESC to control 350W 24V DC motors. Symptoms like voltage sag on battery, but battery is fine (new, genuine samsung cells). Then post your graphs here after the unbalanced current triggers. Main menu. This feature allows you to leave temperature headroom for the brakes to work. Log in or register to post comments; Thu, 2021-01-21 17:31 #3. I get about 20,000 ERPM (20MPH). my idea is to have an acceleration pedal, a brake pedal and a reverse button on ADC imput ADC1 acceleration pedal Guys, I need some help, I'm using a Flipsky 7070 motor in my setup, with a vesc 75100, and a 48v battery only, this motor has a 13-tooth gear, along with a larger 60-tooth gear, to make a reduction , and in this 60 t gear, there is an 11 t pinion, connected to a 54 t ring gear, like a mid drive cyc system, and the question is, why can't I make a uniform acceleration, at the It was working great over PPM + CAN, now it stalls and sputters during even mild acceleration. Well, that's my situation too, 5. How to adjust Duty Cycle Mode accelerate and brake time by VESC TOOL ?Rapid acceleration or brake can throw people away from their electric skateboards. This is the main new feature of FW 4. Better Battery Monitoring Hi Guys, I’ve just completed a new build and for the most part it’s working great. and the user would be required to apply some other brakes or negative throttle to offset their acceleration due to gravity. For batteries im using 2 Lead acid 22A batteries in series. Brakes work as normal. This is the data from the vesc log . 03 - noproblemo, 6. Very unlikely some conversion Upgrade battery, get a VESC, get bigger Motors, get better brakes. I trying to control two Bafang 250w 36v hub motors for a mobile cart. But i want to not have to kick. i think i had the actual electrical braking force and braking regen mixed up in my head. This VESC VESC Project. this means that (4000*[14/2]) = 28000 ERPM. 1 or more means braking is harsher than acceleration (nose softer than tail VESC, or Vedder Electronic Speed Controller, works by regulating the power delivered to an electric motor, controlling its speed, direction, and overall performance. 5A, 100A becomes 50A etc. Some specs: What is wrong with my VESC parameters ? Thank you. One of my objectives is to get smooth, jerk free, acceleration. The goal is for good torque-y When I open the newest Vesc Tool I get warnings that the Firmware is too old and I am unable to use the Input Wizard. Just got everything about hooked up. Those versions are now part of the VESC Tool. Surprisingly, when I use the This is my VESC settings:-Absolutt max current 200a-Motor current max 135a-battery current max 98a-battery voltage cutoff start 52v, end 48v-MOSFET temp cutoff start 80c, end 90c-Acceleration temperature decrease 0% (tried 15% )-Duty cycle 96% (i get to 50% on static thrust test) I have tried the following things: Heres a video of where I am at right now. badger1666. It doesn't seem to change anything when I change the values of "Positive" & "Negative Ramping Time". Click 'OK'. I was not able to ride it and it couldn't provide the power to push the board forward. You'd be better off asking someone like u/samuraipunch or u/DoctorDugong21 or With any small arduino, use analog acceleration/brake throttles to control any electic moving device like escooter, gokart, electric skateboard without using the stock display. 1: Done: I am new to vesc and im not very good with programing. However, a one time manual firmware change is needed. Last seen: 4 years 1 month ago . My issue essentially extends from that fact that when the throttle is hovering around the mid point (either slightly above or slightly below centre) the controller has a tendency to cause the motor to jerk during commutation. Any help? The aim of this guide is to convert a Onewheel+ XR to use an open-sourced VESC based controller mounted in a 3D printed controller box. Bluetooth with VESC tool app on tablet mounted on the scooter handle bars. Math question * 18 + 2 = Acceleration is scary to say the least. 03 and I can send over my entire vesc config file if needed. Let’s get this VESC info in one place so people can have an easier time jumping into VESC tool setup and customization. Enter all your . Can please someone explain me how to smoothen the acceleration ramp in my situation ? Because it's too aggressive every time I use it. My target is 4000rpm, from my 14pole motor. acceleration, braking VESC Project. Observer gain can be 12s voltage = lots of torque and fast acceleration. I can get them to run alright using water cooled 75300 and a 75450, with some decent power flowing, however, I would like to know the steps I can take to test and analyze some acceleration events and fine tune these settings for absolute maximum power delivery One area the VESC performs beyond expectation is the speed control. You will find 2 of these used for your foot sensors, measuring the voltage. acceleration and braking/reverse. In this case the ESC should decrease the acceleration so that the car does not back-flip. Guess what: in 20 tests with this values the acceleration and braking works like a charm. This sudden cutout after acceleration is quite unpredictable and really throws me off. what you see is by super hard acceleration on meadow with backward shifted bodywheight its UN-SENSORED also. Ramp up the amps to taste bear in mind infinite speed is when L*id = lambda. Only a very mild brake force can be handled by the unprepared rider and so should be the setting (e. in v3. All good. I've got all the parts needed for this lying around waiting to put to use Two vesc will be masters and the rest two will be slaves. I . Mainly sensorless open loop ERPM needs to be lowered to 50. E. Then I found the poti is working but the throttle not, then the brake interception when acceleration because of the missing Pullup (in my case) resistor. i bought a flipsky 6. Throttle positive ramping time is set to 0. for 1+3, enter 4. The potentiometer can kind of control the speed of the motor, the first 20% it runs rather slowly, and anything above that is max speed. It was all going well until I started to up the The VESC 75100 controller is connected. VESC Tool>Motor settings>BLDC>Sensors. Last post. Looks. Log in or register to post comments; Sat, 2020-10-17 21:45 #2. 2hw running a 24v 300w 60 rpm rated nema frame industrial servo with reducer The cominations are: 001, 010, 100, 011, 101, 110. PedroMcJimenez March VESC is an open source ESC (electric speed controller), it’s named by its creator , Benjamin Vedder, Vedder’s ESC. 6 mins ago. I have speed ramps programed and with a normal ESC this controls the thrust/energy. I'm running fw 5. inertia. However, I tested upgrading to the new Firmwares 6. So that‘s what we will do Vedders Electronic Speed Controller (VESC) was designed by Benjamin Vedder and is set to revolutionize the electric skateboarding world. Scooter reaches only 50 km/h which i was getting with a much cheaper generic unbranded controller (was going 55 actually), yes it was bigger, louder operation with less options to play with, BUT it was half price Also, the IMU160 as well as the MPU9250 or whatever its number is produce very noisy (to me unusable) acceleration data, so I have to leverage ERPM to measure acceleration. For the current batch 80A seams to be a limit on some motors. They will stop the skateboard quickly 1298 j'aime,75 commentaires. Math question * 1 + 11 = for acceleration: seconds: W: A: acceleration duration to reach Vmax Harsh noise on rapid/high current acceleration, please help! (with images and video!) Hi, I am currently working to tune a VESC to power a vehicle with 4214 Xing Quadcopter motors (660kv). I wouldn’t trust the flipsky enough to go quickly but I Checklist I've read the contribution guidelines. Ride feel and reliability is closing in. I'm noticing a little jerk when the motor starts to move, even at the minimal RPM (which for my motor seems to be at 900 RPM). I want to start from a stand still without kicking, but it seems like my motors are just jittering as i slowly pull the trigger. That’s why people riding VESC XRs have more power than their FM equivalent. This is particularly useful when Vesc x keeps cutting out during acceleration please help ive tried everything. I've searched other issues and no duplicate issues were found. I should probably compare power spectra from the IMU for different control modes. Cette étape sert à mémoriser votre configuration dans la carte VESC. How can I maximize the acceleration? I'm relatively new to this field, and I can't seem to find the necessary information to make the appropriate adjustments. Current control works nice, but when the vehicle is floored and held to max speed, there is a big difference in acceleration when the peak power/efficiency rpms come up. wnfvx ffggecr tnt bhes ngl xolu ncichbm csej cokyavj mhzov
