摘　　要：为解决矿业生产中电机在恶劣工况下转矩脉动高与稳定性差的问题,设计了一种60极72槽内置切向式永磁同步电机,通过场路结合法计算了电机主要尺寸和电磁参数,利用FEA软件仿真分析了方案的可行性,基于田口方法对内置切向式永磁同步电机进行多目标优化,设计正交试验进行有限元分析,计算各个优化变量对优化目标的影响程度,选出了最优参数取值组合。结果表明:齿槽转矩由6.50 kN·m降至1.01 kN·m,降低84.46%;输出转矩脉动降低33.3%,显著抑制了齿槽转矩和转矩脉动。This paper aims to address the high torque ripple and poor stability of the motor under harsh working conditions in mining production and designs a 60-pole 72-slot built-in tangential permanent magnet synchronous motor.The study operates by calculating the main dimensions and electromagnetic parameters of the motor with the field-circuit combination method,verifying the feasibility of the design scheme by FEA software simulation analysis,optimizing the multi-targets at the built-in tangential permanent magnet synchronous motor based on the taguchi method,calculating the influence degree of each optimization variable on the optimization targets according to the results of the finite element analysis,and selecting the optimal parameter combination.The results show that the optimized cogging torque is reduced by 84.46%,from 6.50 kN·m to 1.01 kN·m;and the output torque ripple is reduced by 33.3%,which significantly suppresses the cogging torque and torque ripple.
