Wiring
diagram
Function
The Direct Drive motor can be driven from stopped to maximum speed in infinite
steps in either direction.
There are 36 poles on the stator; 12 permanent magnets spaced around the rotor.
There are no brushes to wear out. Unlike a more traditional brushless motor, the
rotor surrounds the stator rather than being attached to it.
