在永磁同步电动机的工作过程中，效率和转矩脉动往往是人们特别关注的问题。分析了永磁同步电机在工作过程中产生的损耗和齿槽转矩。优化了用于直驱抽油机的低速表面安装PMSM。为了提高效率和减小齿槽转矩，采用田口法，选取定子轭架高度、定子齿宽度、永磁体厚度和气隙长度作为变量。采用有限元法进行正交试验。分析结果的均值和所选变量之间的二阶交互效应，通过方差分析确定最佳优化组合。结果表明，田口的方法是一种高效、有效的方法，并最终通过样机试验得到了验证。
Efficiency and torque ripple are usually especially concerned during the working process of permanent magnet synchronous motor (PMSM). The loss and cogging torque generated during the working process of PMSM are analyzed. A low-speed surface-mounted PMSM used for direct-drive pumping unit is optimized. For increasing efficiency and reducing cogging torque, Taguchi's method is employed and height of stator yoke, width of stator tooth, thickness of permanent magnet, and air-gap length are selected as the variables. The orthogonal experiment is conducted with FEM. The mean of the results and the two-order interaction effects between the selected variables are analyzed, then the best optimization combination is determined by the analysis of variance. The results show that Taguchi's method is an efficient and effective approach, which is finally proved by the prototype test.
