Abstract
A reluctance motor/generator system in which a winding failure event in one channel of a multiple channel multiple phased stator assembly is accommodated by removal of the failed winding from the reluctance motor/generator machine's electrical circuit using electrical switching and an acceptance of reduced machine output capability. This electrical switching also accomplishes a reversal of magnetic polarity in poles of one remaining normal channel of the machine. The magnetic polarity reversal as accomplished electrically largely excludes secondary magnetic flux from stator poles carrying the failed winding and its associated phase windings of the channel and thereby precludes electrical energy generation in the failure event pole. In the thus achieved channel-removed mode of machine operation, a different more elongated magnetic flux path through the machine rotor and stator elements becomes active and provides reduced but usable electrical output from the machine. Military and non-military uses of the system in both motor and generator functions are contemplated. Aircraft and ground-based uses of the invention are also contemplated.
