Switched reluctance machine capable of improved fault operation

摘要

A switched reluctance machine capable of improved operation under fault conditions. The machine includes a controller which responds to a fault in a phase winding by cutting off current to the phase windings of all stator poles that are aligned with a rotor pole at the time the stator pole having the phase winding with the fault therein aligned with a rotor pole. Consequently, there is no magnetic flux in the stator or rotor at such time. Therefore, no current is induced in the faulted phase winding. This avoids generation of a counter torque, as well as avoiding potential catastrophic failure of the SR machine.
