Does anybody have a clue on what could cause a motor to behave like this?
(check video please)
I made another post where I detailed things a little further, but maybe it will be easier if I try to fix one bizarre problem at a time.
It's a 6355 190Kv sensored brushless motor, with a 4.12 VESC and 12S3P batteries.
In the video, I tried to set it to 80A (as another user has suggested), but the only thing it changed was the sound got louder and more annoying.
If I go super easy on the throttle it's ok, but as soon as I put some load on it or just twist the throttle too fast, THAT happens.
Any clues??
I am also having the same problem.
Do you have any idea how to solve this problem?? Or do you know under what conditions this occurs?
Nop, I have no idea, but it's a general consensus the older VESCs can't handle more than 30A properly and for a bike it's required at least 60A (80A recommended).
I bought a VESC 6 but didn't had the time to install and test it yet.
just try with sensorless mod.
Dear Frazatto, Thanks for your reply.
Dear skyline1970, I am with sensorless mod but still having issues.
sound says that motor does not get normal switching signals,
reduce pwm sw. freq. and try,
or just try with bldc mod.
I think this problem has been solved with the newly updated VESC-Tool and FW(5.03). When I tested it, there are no problems yet.
If it happens, PWM freq. I'll try to fix and test the BLDC mod.
If anyone else has the same problem as me, see my post. I uploaded a video of the problem I encountered.

Thank you.
Im a bit new to VESC and i have the same problem. Can you tell me what pwm sw. freq. is?
