摘　　要：为了提高车用永磁同步电机在行驶过程中的性能,降低齿槽转矩,将永磁同步电机转子结构的多重复杂关系归约为三个变量。以转子磁钢的厚度、气隙和槽口宽度为优化参数,通过正交实验方法得到的最优变量组合对齿槽转矩、电磁转矩进行分析设计。在此基础上,使用Maxwell软件对电机进行了有限元仿真实验,优先选择齿槽转矩最低的设计变量组合。实验结果表明,与优化前相比,电机的齿槽转矩明显降低,运行性能得到了有效提升,在实际应用中具有可行性和有效性。The miscellaneous relationship of the rotor structure of PMSM is reduced to three variables to improve the performance of vehicle-mounted PMSM during driving and reduce the cogging torque. By taking the thickness,air gap and slot width of rotor magnetic steel as the optimization parameters,the cogging torque and electromagnetic torque are analyzed and designed with the optimal variable combination obtained by orthogonal experiment method. On this basis,the finite element simulation experiment of the motor is carried out by Maxwell software. The combination of design variables with the lowest cogging torque is preferred. The experimental results show that the cogging torque of the motor is significantly reduced and the operation performance is effectively improved in comparison with that of the motor before improved. To sum up,the Taguchi algorithm is feasible and effective in the application.
