The cheap motor analysers are relatively accurate (say within 1 deg consistently), have anyone else try to align bad sensor board to gain performance?
The simple answer is yes. I've compared badly aligned sensor board with a good aligned sensor board and I can tell the difference on the track in 17.5T motors. Can't speak on other motors, or on a dyno. I did keep everything the same in my testing, even the amp draw on the motor.
With this said, I think that the affect of having a bad sensor could be overcome by writing smarter ESC software that adjusts the timing of the pulse between the poles. I'm not sure how the software is currently handling the amount of time between reading the hall sensors and when they actually pulse the poll with voltage. So maybe some ESC just keep the time equal between all three phases and others might be smarter about how they handle it.
