Abstract
A switched reluctance machine comprises a stator having an even plurality of salient stator poles, each of which having a stator winding disposed thereon and electrically coupled one to another to form diametrically opposed pole pairs which may be coupled to an external source of electrical energy, a rotor having an even plurality of salient rotor poles, and at least one compensation coil disposed on each of the rotor poles. The compensation coils are electrically coupled one to another to form diametrically opposed compensation pairs in which flows a flux generating current when one of the stator windings of a pole pair is either open of shorted. The flux generated equalizes the unbalance forces resulting from the faulted stator winding, thereby increasing the fault tolerant capability of the switched reluctance machine.
