To reduce stray magnetic fields and the accompanying inefficiency in electric motors, the present specification provides a motor having a plurality of stator poles and rotor poles. The rotor poles are configured to rotate across the stator poles. Each of the rotor poles has a first rotor pole component and a second rotor pole component disposed on opposite sides of the plurality of stator poles. Each of the stator poles comprises at least a first sub-pole and a second sub-pole arranged such that at least a portion of magnetic flux from the first sub-pole flows through the first rotor pole component, through the second sub-pole, through the second rotor pole component and back through the first sub-pole. As the rotor poles rotate with respect to the stator poles, the magnetic flux exerts a rotating force on the plurality of rotor poles. |
