ABSTRACT:
A reluctance machine includes a stator and a rotor. The stator and rotor have a same number of poles. The rotor is configured to rotate about an axis of rotation. Each stator pole is formed of a primary stator pole and an auxiliary stator pole. The auxiliary stator pole is axially aligned with the primary stator pole in the direction of the axis of rotation. Each rotor pole has a length extending in the direction of the axis of rotation sufficient to at least partially cover the primary stator pole and axially aligned auxiliary stator pole. The primary stator poles are actuated with an alternating magnetic field orientation, and the auxiliary stator poles are also actuated with an alternating magnetic field orientation. The field orientations for the primary and auxiliary stator poles are, however, opposite each other such that a primary stator pole its axially aligned auxiliary stator pole have opposite magnetic field orientations.
