4-9-2. STATOR ASSEMBLY
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.
