(Windings)
The DD 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.
