Abstract
A low-vibration fault-tolerant current algorithm for six-phase permanent magnet motors under open-phase faults is provided. When a six-phase permanent magnet motor is supplied through a full-bridge configuration, the vibration performance of the motor dramatically deteriorates if the open-phase fault occurs. The types of open-phase faults include one-phase open-phase, adjacent two-phase open-phase, non-adjacent two-phase open-phase, and at most three-phase open-phase faults. To suppress the deterioration of the vibration response when open-phase fault occurs, the remaining phase magnetomotive force is reconfigured based on the reverse magnetomotive force in the synthesized magnetomotive force from the residual phases under different open-phase fault types, and the remaining phase currents are adjusted to maintain normal vibration response.
