Versions: – It comes in two (2) different versions to serve users better and prevent the high cost of entry. hese servos are used to drive the seven a robot arm currently under development. edu I'm building a high torque application and need some configuration advice for my current setup. On a hill, I tested this original motor with 60 phase current, and it was twice as fast (12km/h) compared with the original motor controller and original 36V battery. Read more at http://vesc-project. The ERPM max I have set is 3600 (200 RPM * 18 pole pairs) The control type/mode/application is ADC No DC is connected to VESC, it powers up once the generator starts rotating above 150 RPMs which puts about 14V on the DC bus of VESC. I believe the input current is not enough to overcome the deadband torque of the motor. The EBike application reads the input sensors as the throttle, maps the throttle value to a motor current (motor torque), and finally send this value to VESC motor controller, that will make the motor rotate with this specific current / torque. com’s Torque ESCs Why is VESC so great? VESC is excellent because it allows tons of customization. Designed to replace traditional ESCs (Electronic Speed Controllers), VESCs offer advanced features and unparalleled performance. comPrevious video: https://youtu. If the load on the winch exceeds the torque set by your current setting, your winch will unwind the cable, and opposite if the load is lower. If you follow it from top to bottom you should be able to setup your VESC and have a rideable board to then fine tune to your riding style.

Jan 3, 2022 · In the case of On-Off type, once pedal rpm is above a certain value there would be a constant power/throttle, else no assist, while in Cadence control type, speed or torque (& perhaps power?) is proportional to the pedal rpm. I use the throttle in duty cycle as I feel it more natural and also because it has more torque on startup than in current mode at full throttle. May 26, 2025 · Nowadays, people demand more convenience and intelligence from their transportation tools. Nov 30, 2024 · VESC Tool: The primary software for configuring and monitoring VESC controllers. Oct 1, 2023 · Field Oriented Control (FOC) method is a solution for controlling BLDC motor, because it has the advantaged of overcoming torque ripples at low speeds. Haven't decided how to do it yet. Pros: Fully programmable (using tools like VESC Tool). spintend is my go to; good place on the price to quality axis. Feb 12, 2024 · I have it connected to the VESC Tool software and I can read and write to the drive, no problem. All this raises the question: how can I control two different motors with VESC? Your motor feels like it’s losing torque at 3-4mph and makes crunchy/cogging sounds when braking hard or accelerating? What is it? 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. It would be a subsystem in a control loop that would continuously adjust the torque applied to a torsional spring. 00 beta 40. be/W9IHEqlGG1sMake The unreleased VESC 6 could be able to control around 50 continuous amps. com) VESC Version 4 vs Version 6 VESC comes in two main versions, version 4 and the newer version 6. Until now! Native CANbus support for VESC Tool See here our Pull Request that adds native support for a can interface. Bench Testing: Before installing the build on your Onewheel, perform thorough bench tests to verify proper operation, motor control, and safety features. This is the source code for the VESC DC/BLDC/FOC controller. I would definitely need to create a custom application and I think PAS is kind of what I am looking for. I didn't even t Nov 22, 2019 · Examples of VESC derivatives not named VESC: Enertion’s FOCBOX line of ESCs Flipsky’s FSESC line DIYelectricskateboard. My question is: What would be the best way to get the effect of an (adjustable) limited slip differential with 2 VESC controllers? Or is "Torque Vectoring" better? Field-Oriented Control Field-Oriented Control is a technique for controlling brushless motors that allows us to maximize the torque output that we can get from a motor. By doing so, when I stop accelerating, the vesc understand "0 rpm" May 2, 2019 · The VESC Tool will already have selected the correct firmware for your device so there's no need to select any manually. Most of the time the torque would be constant, so the motor would not be rotating. Is Jan 7, 2015 · Traction control can also be enabled, which reduces the torque on motors that spin faster than the slowest motor proportional to their speed difference. May 17, 2019 · 1. I was initially going to rip it all out and replace with a vesc and thumb throttle, but the torque sensing crank has grown on me Mar 29, 2025 · More difficult to set up than other ESCs Overview: The most sophisticated and feature-rich ESC for combat robotics is VESC. It mainly focus on electric firmware and hardware designing, manufacturing, marketing and serving in intelligent control Jan 7, 2015 · Traction control can also be enabled, which reduces the torque on motors that spin faster than the slowest motor proportional to their speed difference. This works best when matched to motor with sine wave back-emf. Sep 4, 2017 · With all the sophistication of the VESC, I would imagine this should be a no-brainer to implement, unless I am missing something. Top speed is not important, but the ability to start from a dead stop and pull the most weight is the only goal. Instant torque and power, stable off road performance, responsive throttle, refined pedal assist experience, the X-series controllers are the key components to power all CYC motor systems. Jul 20, 2025 · To do this, I plan to use an ESP32 to process slope and elevation data from a virtual ride, and then send appropriate commands to the VESC to adjust the braking torque in real-time. VESC has PPM input and I want to know if it is connected to hardware timer that is capable to convert this pwm at 10kHz to some integer +- 1000 so I can run torque control on VESC and position control on PC with linux/mesa. Nov 30, 2024 · VESC Tool Setup: Connect the VESC controller to your computer using a USB cable and utilise VESC Tool software to configure motor parameters, battery settings, and other essential settings. VESC is able to drive any motor, has a motor auto detection feature and is very easy to configure. My goal is to reach the slowest possible RPM with closed loop control. Adding position sensors does increase cost. Aug 26, 2024 · Well if you are working with a VESC, you *may* be able to just read the torque signal on the throttle input (ADC1,ADC2) You may have to scale the signal in VESC settings to work how you want it. Your choice of commutation mode is either bldc (trapezoidal) or foc. Prototype quality PCB ($2) & Stencil ($7) : https://jlcpcb. According to ebikes. With another motor it delivers 50A but this motor is twice as heavy as the one I wan't to use and that can deliver the torque. While torque sensing pedals remain unsupported, the project highlights the benefits of open-source controllers for maintaining and customizing e-bikes beyond proprietary limitations. This library provides a simple and easy-to-use interface to control the VESC controller. – Version 4 is excellent for street and normal, everyday usage. It has a bafan hub motor, torque sensing crank/PAS and a can buss controler. Here is the sampled data during the jittery operation. In simplified terms, it’s the brain of the device that controls the speed (current) of the motor or how hard it should break, and regenerate the energy. The lecture video covers field-oriented control for electric motors so see that for details, but here are some great links for motor control. Spintend is your best one stop shop for affordable ESC based on VESC (75v/100v) big motors remotes and throttle for converting your skateboard, bike, boat, robot, one wheel scooter to motorized one.
