Investigation on Slot and Pole Combination Schemes for Six-phase Fault-Tolerant Permanent Magnet Rim Driven Motor

In order to improve the reliability of marine electric propulsion system, the topology of fault-tolerant permanent magnet rim driven motor is proposed. The slot and pole combination and winding distribution of six-phase fault-tolerant permanent magnet rim driven motor are theoretically analyzed. Besides, the general design method is given. The simulation results of finite element analysis is provided to verify the short-circuit current suppression capability and mutual inductance reduction method in different case of slot and pole combination, which provides a reference for the application of fault-tolerant permanent magnet rim driven motor in ship propulsion field.
