Abstract
A rotor for mounting on a rotational axis in an axial flux electric motor includes a ferromagnetic rotor core. The rotor also includes a plurality of alternating south and north pole permanent magnets (PMs) arranged on the ferromagnetic rotor core symmetrically around the rotational axis and facing the stator. The ferromagnetic rotor core includes a plurality of core saliencies extending to the rotor exterior surface. Each of the core saliencies is arranged between one south pole PM and one north pole PM. The plurality of core saliencies is phase-angle shifted relative to the plurality of alternating south and north pole PMs to thereby alter magnetic reluctance of the electric motor. An axial flux electric motor employing the above-described rotor is also contemplated.
