Abstract
An apparatus is provided for forming an axial flux permanent magnet synchronous motor. The apparatus includes a stator assembly including a plurality of stator poles spaced about a stator shaft, each comprising a winding. Adjacent pairs of stator poles have a spacing in a circumferential direction approximately equal to or greater than a width of the stator pole. A rotor assembly includes a plurality of rotor poles of alternating magnetic polarity arranged for electrically communicating with the windings of the stator assembly. The ratio of stator poles to rotor poles may be less than 4:6 or, more specifically, less than or equal to about 1:2.
