本研究提出了一种潜水式永磁同步电机（PMSM）的优化程序，以同时实现最大效率和最小齿槽转矩。许多几何参数可以用来定义潜水式永磁同步电机。为了确定最重要的优化参数，考虑到相互作用效应，采用实验设计外的分数因子设计（DOE）进行筛选活动。电机的制造过程会产生尺寸公差、形状和位置公差、安装误差和材料性能偏差。为了保证潜式永磁同步电机具有良好的鲁棒性，采用田口鲁棒设计方法。将筛选出的重要参数作为控制因素。噪声因素包括定子内径、气隙长度、磁体剩余物和磁体尺寸公差。数值结果表明，该方法是提高潜航式永磁同步电机性能的一种有效的优化设计方法，并通过样机试验进行了验证。
This study presents an optimisation procedure for a submersible permanent magnet synchronous motor (PMSM) to achieve the maximum efficiency and minimum cogging torque simultaneously. Numerous geometric parameters can be used to define submersible PMSM. To identify the most significant parameters for optimisation, the fractional factorial design out of design of experiment (DOE) is employed for the screening activity, considering the interaction effects into account. The manufacturing process of the motor causes dimension tolerances, shape and position tolerances, installation errors and deviations of material properties. To ensure a good robustness for the performance of the submersible PMSM, Taguchi's robust design method is employed. The screened significant parameters are taken as the control factors. The noise factors include inner diameter of stator, the air-gap length, the remanence of the magnets and the dimension tolerances of magnets. Numerical results demonstrate that this method is an effective optimisation design procedure to improve the performance of submersible PMSM, which is finally proved by the prototype test.
