摘要
The development of rare earth permanent magnet materials has made outstanding contributions to the advancement of high performance permanent magnet synchronous motors (PMSM). However, the non-renewable and strategic protection of rare earth resources leads to price fluctuations and supply risk of rare earth permanent magnets, limiting electrical vehicle development and popularity. In this paper, we optimized the design of the nanocomposite magnet microstructure and proposed a combined-pole interior nanocomposite permanent magnet synchronous motor (CP-INPMSM), combining nanocomposite magnet and PMSM. The simulation results show that the no-load back-electromotive force and torque of the motor are improved. This design can reduce the usage of rare-earth permanent magnet materials and improve the electromagnetic performance of the motor.
