It's indeed a standard Lyen without any modifications. Got one from a forum member for testing.
The motor does 167kv according to HK. The batteries are 45V so thats about 90k erpm?
I will look into the C20 mod. But the controller seems to cut out at an alarmingly large no load current.
Below this current it seems to behave normal without any cutouts.
The motor is delta terminated. I read that with delta you need to place the sensors in between the same phase wires which are wound in the same direction?
The stator poles are numbered (photo
). I have put the sensors in between same numbered poles.
The phase wires coming out of the motor are also not marked. So just scoped one of the hall sensors and found the matching pole wires and called them both A.
I did the same thing for the other poles. Don't know certain if this is the right method?
I just tried another hall setup. This time I again put them in between poles with the same number but these where shifted 60 degrees from the first hall setup.
The same problem occured. Maybe next time I should try putting them in between poles with different numbers.
But thats something for another day
The ringing could be a problem with the sampling frequency of the camera mic. Can only hear it in the movie.
Thanks a lot for the help!
