Abstract
The present invention relates to a motor having a stator with a magnetized rotor rotatably positioned in the stator. The stator and the rotor each have at least two magnetic poles. At least one of the stator poles has a different area confronting the poles of the rotor than the other stator poles. An air gap is positioned between each of the at least two stator poles and at least two rotor poles. The distance of the air gap between each stator pole and each rotor pole is different. A coil is wound upon a bobbin which is placed about at least one of the stator poles. Altering the confronting area of the stator poles allows a larger bobbin and coil to be placed about the stator pole.
