为了提高电机的性能，需要获得磁路中结构的最优拓扑。应用均匀化设计方法获得最优拓扑。在该方法中，内孔尺寸和单元旋转角度的变化决定了设计区域内的最佳材料分布，这种分布定义了最佳拓扑结构。目标函数被定义为最大化磁平均顺应性（MMC）。这与最大化磁矢势和e相同！目的是提高电磁铁的性能。基于三维六面体单元进行分析和优化。将该设计方法应用于H型电磁铁（H磁铁）。版权所有（2000年约翰威利父子有限公司。
To improve the performance of electric machinery, it is necessary to obtain the optimal topology of a structure in magnetic "elds. The homogenization design method is applied to obtain the optimal topology. In the method, the change of inner hole size and rotational angle of unit cell determines the optimal material distribution in a design domain and this distribution de"nes an optimal topology. The objective function is de"ned as maximizing magnetic mean compliance (MMC). This is the same as maximizing magnetic vector potential and e!ective to improve the performance of electomagnet. The analysis and optimization is performed based on three-dimensional hexahedral elements. This design method is applied to the H-shaped electromagnet (H-magnet).
