Motors
I acquired two protean hub motors. I think they were manufactured for some wind turbine project, but I’m not sure. They have no documentation I know of.
They are 3 phase, with a sin/cos encoder. The guy I bought them off had one spinning using a recently released Kelly KHS controller. The motor data connector has a weidmuller on it.
He also had one taken apart, and I took some photos of the inside.
The motor has an internal spline and a bearing.
This is the wheel side of the motor, which has no bearing, but from where the spline is more clearly visible.
The spline has 30 teeth.
