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.
