Stator Structure Optimization of Permanent Magnet Synchronous Motor for New Energy Vehicles

In this paper, the stator of permanent magnet synchronous motor is selected as the research object, and the design characteristics of permanent magnet synchronous motor are analyzed in combination with the performance requirements of new energy vehicles for driving motors. Through the modeling and simulation of Motor-CAD (Computer Aided Design) software, the stator of permanent magnet synchronous motor is simulated and designed, and the performance of the motor is comprehensively analyzed and the stator winding loss is calculated by using finite element analysis method. The performance difference of the motor under different stator structure parameters is compared, and the relevant electromagnetic parameters are optimized, and the design scheme is proved to be scientific and reasonable.
