永磁电机具有结构简单、免维护、高性能等优点，在工业领域得到了广泛的应用。针对永磁同步电机在大功率使用时存在的成本和重量问题，提出了一种基于非线性优化技术的表面式永磁同步电机（SPMSM）优化设计方法。在制定中，使用空间谐波分析的性能特性估计。通过实验验证了公式的准确性。应用外点变换法和单纯形法求解约束非线性规划问题。选取极数、叠层高度、每极每相槽数、线圈节距、槽宽与槽距之比、磁体宽度、磁体高度和转子磁轭高度等8个参数作为自变量。在四个目标函数下分析了SPMSM的设计;主要重量，材料成本，输入KVA和功率率。
Permanent magnet (PM) motors, which have a simple and maintenance-free structure and high performance, have been used widely in the fields of industry applications. The PM motor, however, has some problems on the cost and weight in high power usage.In this paper, we propose a method for optimizing surface PM synchronous motors (SPMSM) using non linear optimization technique. In the formulation, the performance characteristics are estimated using space harmonic analysis. The accuracy of the formulas is investigated by experiment. The exterior point transformation method and the simplex method are applied to solve the constrained nonlinear programming problem. Eight parameters are chosen as the independent variables, such as number of poles, the stack height, the number of slots per pole per phase, the coil pitch, the ratio of slot width to slot pitch, the width of magnet, the height of magnet and the height of rotor yoke. The SPMSM design is analyzed under four objective functions; the primary weight, the cost of materials, the input KVA and the power rate.
