VESC 6, controlling 1000w 8in hub motor with 18 in tire. No load added. ~50v power suppply.
Motor runs OK in hall mode (i set sensorless ermp to 8000, 6000erpm is the max RPM this motor can reach)
If i set sensorless model to 2500 or 1500 ermp, motor knocks really bad when reaches that speed and fails to accelerate. I tried doubling and halving observer gain, motor runs somewhat OK when observer gain is reduced 10x from what its detected value is 0.6 to 0.04
I would appreciate the ideas to solving this tracking problem
Running the detection at much higher current produced different resistance and inductance values, which solved the problem.
It would be very helpful to have a troubleshooting guide, describing how to get a motor running properly and most common problems. Does anything like that exist already?
