摘　　要：针对双V型内置式永磁同步电机(IPMSM)齿槽转矩较大的问题,根据齿槽转矩的产生原理,借助ANSYS maxwell有限元仿真软件建立10极60槽内置式双V型永磁同步电机模型,探讨在定子和转子上同时开对称辅助槽的可行性,运用双变量参数化分析定子和转子上开对称辅助槽位置、半径对齿槽转矩的影响。最后对比分析开对称辅助槽前后电机的各项性能,结果表明:合理开设定子和转子辅助槽能有效削弱齿槽转矩并保证电机其他性能基本不变。Aiming at the problem of large cog torque of double V-type built-in permanent magnet synchronous motor(IPMSM), and according to the generation principle of cog torque, a 10-pole and 60-slot built-in double V-type permanent magnet synchronous motor model is established by means of ANSYS Maxwell finite element simulation software. The feasibility of opening symmetric auxiliary grooves on both the stator and rotor at the same time is discussed. The influence of location and radius of the auxiliary grooves on the cog torque is analyzed by using bivariate parameterization. Finally, the performance of the motor before and after grooving is compared and analyzed. The simulation results show that the reasonable setting of stator and rotor auxiliary grooves can effectively reduce the cogging torque and ensure the other performance of the motor unchanged basically.
