摘要：为降低内置式永磁同步电机齿槽转矩，提出一种新的转子开槽设计方法。首先给出了齿槽转矩解析式，从解析式上分析了转子开槽降低齿槽转矩的有效性。然后，以12槽10极内置式永磁同步电机为例，结合有限元软件对转子开槽半径与角度进行了扫描仿真，给出了最优齿槽转矩下对应的开槽半径和角度。最后，分析了转子开槽对电机运行性能的影响。结果表明，合理的对转子开槽设计可大幅降低电机齿槽转矩，同时保证其它性能参数在较优范围内。

Abstract: To reduce the cogging torque of Interiortype permanent magnet synchronous motor（PMSM）， a new rotor slotting design method was presented in this paper. First， given the cogging torque analytical formula， based on the analysis of analytical formula， the cogging torque can be effectively reduced by rotor slotting.Taking a case study of 12 slots 10 poles interiortype PMSM for example, the simulation of rotor slot radius and angle were carried out with finite element software. Meanwhile， the best rotor slot radius and angle were given. In the final， analyzed the effect of rotor slotting on motor performance. The results show that reasonable slot design can greatly reduce the cogging torque, while ensuring that other performance parameters are in the best range.
