Abstract
An electric motor includes a stator and a rotor rotatable relative to the stator. The rotor includes a plurality of poles, each of which is defined by a pair of magnets positioned relative to each other in a V-shaped arrangement having a vertex positioned radially inward. Each of the poles includes a mechanical pole angle defined by the pair of magnets. The mechanical pole angle is about one-half of three hundred and sixty divided by the number of the poles of the rotor.
