| Abstract: | By means of finite element analysis, the topological structure of permanent magnet synchronous motor (PMSM) used in electric vehicles is optimized to improve the magnetic flux leakage phenomenon and the air gap flux density. The harmonic content of the no-load inverse potential is reduced and the sine of the waveform is increased by the method of rotor pole. On this basis, the global optimization is carried out with the aim of minimizing the rated torque and the volume of permanent magnet based on genetic algorithm, which saves the consumption of permanent magnet and reduces the production cost of motor. The optimization process can be used as a reference to improve the performance of the built-in PERMANENT magnet synchronous motor (PMSM) for electric vehicles. |
