Abstract

There are provided electric motors each having a rotor, a stator, and a plurality of conductive windings each disposed around a corresponding tooth of the stator. The rotor is to rotate about an axis of rotation defining an axial direction. The rotor includes a backiron and a plurality of magnets secured to an inner surface of the backiron. The stator is disposed inside the rotor and centered about the axis of rotation. The stator includes a plurality of teeth each extending radially relative to the axis of rotation towards the inner surface of the backiron and terminating in a corresponding tooth end disposed proximal to the inner surface.
