i run motor in torque control mode, i run +2 v and -2 v and get different diagrams for pwms sent to driver!
here is 2 v , -2 v:
here is +6 v, -6 v:
i also notice strange kick in one direction of rotation while i have a smooth rotation on the other direction. when i rotate motor freely by hand, i don’t feel any difference
any idea, what’s the problem here?

Happy New Year. Im sure people are drinking and eating and celebrating. Im too. There is more to life than hanging around a BLDC hobby board.
Wait until they get over the hangover.
Cheers,
Valentine
