I am being trying to run BMSBattery Q85 motor with my firmware as 6 steps and SVM for a possible FOC. I also have BMSBattery S06S controller to run this motor.
What I found (with no load):
- 6 steps gives the less noise and less current (1.8A at 30V and max speed)
- sinewave from S06S controller gives more noise and higher current (2A at 30V and max speed). Also the voltage increases on the power supply, from 30V to 31V!!
- SVM for FOC, gives even more noise, runs slow and higher current like (6A at 30V and max speed). Also the voltage increases on the power supply, from 30V to 34V!!
Does anyone knows why this happen?
I put a 3 resistors in a start connection and connect to each motor phase, turn by hand the motor and the BEMF voltage shape is sinewave so I would expect that this motor should run with a sinewave/FOC...
