UA_Iron,

If you zoom in on the pictures in post #12 of this thread, you can see where it says 1.2 deg on the motor, then on the drive it has a 3wire U,V,W connection to the windings instead of a 4 wire phase A and phase B.

I think this is the motor here
Leadshine Technology Co., Ltd.
because its 5.8 amp, like in the picture

(I think its a special high pole count brushless 3phase motor. )
