mitsui:

What current sensors are you using? For high powered applications, +/-3amp is pretty normal for the swing. Even at zero throttle, the controller is actively commanding 0 torque (Iq = 0). When it's in a car (or gocart) you don't notice it. Since it's torque command and not speed command, it's not intended for applications where it's unloaded. The only reason why I can think it is running rough is wrong PI values or some issue with a position sensor.

Thank you for the kind words Chaz!

arber, I've only tested the leaf motor with the stock resolver. I can't say what is happening there.
