Abstract
A switched reluctance machine having salient stator and rotor poles. Alternating ones of the stator poles having windings and the others having permanent magnets attached on their pole faces. The alternate stator pole windings are provided with polarities that are suitable for unidirectional and bidirectional current operation of the switched reluctance machine. The alternate poles with permanent magnets in the switched reluctance machines can have also concentric windings placed on them and excited with currents to further augment the flux linkages in the stator poles. The windings on the poles with permanent magnets can be excited from the same source as the windings on the poles without permanent magnets to enhance power output or provide power factor correction.
