Axial air gap electric rotary motor

An electric motor assembly comprising a stator having a first radially extending stator pole section, a rotor having a first rotor pole section extending radially from a rotor shaft and a second rotor pole section extending radially from the rotor shaft and spaced axially from the first rotor pole section, the first stator pole section disposed axially between the first and second rotor pole sections and radially overlapping both the first and second rotor pole sections, the stator comprising windings operatively configured to be selectively energized to provide a flux path across a first axial air gap between the first rotor pole section and the first stator pole section, and the first rotor pole section comprising a plurality of radially extending solid unitary pole pieces spaced circumferentially about the central axis of the rotor.
