Abstract
A switched reluctance motor drive or generator takes advantage of the characteristic independence of concentrated phase windings to optimize fault-tolerant operation. No 'dead zones' in motor torque production or generator voltage output are created by faulted phases. One embodiment prevents unbalanced magnetic pull on the rotor despite deactivation of a faulted phase by employing multiple pairs of opposed stator pole windings in each phase.
