Abstract: Aiming at the problem of high cost of rare earth permanent magnets in permanent magnet drive motors for electric vehicles, a new type of permanent magnet reluctance motor was studied. By adopting a hybrid magnetic steel rotor structure based on neodymium iron boron and ferrite, the manufacturing cost of the motor was greatly reduced, and the cost performance of the motor was significantly improved. Aiming at the problems of excessive torque ripple and insufficient torque output capability of the new type permanent magnet reluctance motor, a tangential hybrid magnetic steel rotor structure was further proposed, and the tangential magnetic steel mixing ratio and position placement parameters were optimized.By building a JMAG-MATLAB-PSPICE joint simulation platform, a simulation experiment was performed on the steady state and dynamic performance of the new motor. The experimental results verified the feasibility and effectiveness of the scheme.
