Hi all,
I am using a vesc to control a mower on slopes/hills and wondered if there is a way to set a max speed for down hill only.
What I am thinking is like traction control, but down hill descent control, so that the mower doesn't run away.
Any ideas would be greatly appreciated.
Has any work been on using VESC to control a mid-drive motor on an electric bike?
Hi, I wanted to ask for help with a specific issue I am having. Basically the motor stutters/cogs up and vibrates loudly in certain situations such as: large accelerations, large throttle values, switching from Hall sensors to sensorless mode, reaching certain speeds (usually around top speed). It's a brushless direct drive hub motor for an e-bike, and I haven't experienced this problem with other controllers before. It can happen in both sensored and sensorless mode and at any speed, but it doesn't always happen.
People have told me that Flipsky FSESCs are not well able to handle anything over 12s. Is that true? I have a 4.20 Flipsky FSESC.
Hi guys,
I have a new Stormcore 60D+ driving 2x hub motors on an off-road e-skate board in FOC mode. I'm using a 10S9P battery.
Key parameters:
Motor current 30A, Braking current -20A, Regen current -20A, Absolute max 200A, FOC settings determined using the test in VESCTool. And yes, both sides have the same settings :)
I have been planning to buy this Gearbox (see link below) for my E-scooter project, it has an option for a IMPSM (Internal Magnet Permanent Stator Motor) the D7500 (linked below), which I assume should work the same way as a BLDC motor with a Vesc, right?
Hello,
I am developing a custom motor and am trying to control it with VESC.
The motor works on a normal hobby BLDC controller, but drawn to VESC since I like that it has speed control and FOC built in.
The motor has a large air gap. The magnetic field is about 1/5th as strong as most typical motors. My theory is that the field is not strong enough for the FOC control algorithm to figure out the speed or position of the motor so it ends up just spazzing out.
Here are some videos of me trying to run the motor:
Hello everybody,
I want to control the Vesc via Matlab over Uart. Does anyone have some tips for me or example code that helps me getting started?
I'm searching the whole day for existing solutions but i didn't found anything helpful, at least in my eyes. Thank you for your support!

I'm using VESC in sensored mode with ME0907 motor that has Hall sensors. The system works fine, however at some specific RPMs the motor makes very loud noise. If I switch to sensorless mode the noise goes away. What could be the reason for it? Where should I start digging? Thanks
Hi everyone,
I recently purchased some VESC 75V 300A units and trying to use those to replace Kelly KLS7245N controllers which are rated at 350A. The motor is Motenergy ME0907.
