Comparison Electromagnetic Characteristics of Multi-phase SPMSM for Electric Vessel According to Pole/Slot Combination under Fault Operation

Electric vessel propulsion motors require high reliability and fault tolerance. Therefore, the initial design step of the motor and its interpretation during fault operation must be considered. So, through FEA, the phase angle difference of circuit current, the electromagnetic field performance during normal operation, and electromagnetic filed performance during fault operation are compared and analyzed for each pole/slot combination, and an excellent model is proposed.
