ABSTRACT:
A motor control assembly and method of controlling a motor includes a three phase variable reluctance motor. Each phase includes two separate coils driven by separate driver circuits under the control of a microcomputer. The microcomputer monitors feedback from each driver circuit to determine faults or errors in the driver circuits or respective coils. In the case of a fault detection, one of the driver circuits and coils for each phase may be disabled to allow continued operation of the motor with the remaining driver circuits and coils.
