Abstract

This paper presents a novel reverse salient pole flux controllable permanent magnet (RSP-FCPM) motor topology, and the motor rotor is reasonably designed to have reverse salient pole characteristics and flux controllable characteristics. After selecting the design variables for the RSP-FCPM motor using sensitivity analysis, a multi-objective genetic algorithm is applied for multi-objective optimization. The optimized RSP-FCPM motor is simulated and compared, and the results show that the optimal RSP-FCPM motor has better flux weakening capability, wider speed range, and constant power output area. it can solve the problem of difficult flux changes of the conventional interior permanent magnet motor, and other electromagnetic performances are also more advantageous. To confirm the reliability of the rotor structure during operation, a stress analysis of the rotor is performed, and the results show that the rotor structure can fully withstand high-speed and high-temperature conditions and can operate safely and stably. It also has more advantages in noise performance, which has great prospects for application in the field of electric vehicles.
