本文介绍了一种新的参数优化（PO）和拓扑优化（TO）方法的混合。将该方法应用于永磁电机的优化设计。通过同时执行PO和TO，对转子铁芯的磁通屏障的磁体形状和拓扑进行了优化。在优化过程中，采用了自动网格剖分的方法，提高了形状表示的分辨率。结果表明，所提出的混合优化的平均转矩的增加是大于传统的TO，其中只有磁通屏障的拓扑结构进行了优化。将总转矩分解为磁体转矩和磁阻转矩表明，通过所提出的方法优化的转子中有效地产生磁阻转矩。
This article introduces novel hybridization of parameter optimization (PO) and topology optimization (TO) methods. The proposed method is applied to the optimization of a permanent magnet motor. The magnet shape and topology of the flux barrier of the rotor core are optimized by performing PO and TO simultaneously. In the optimization, automatic mesh generation is adopted to improve the resolution of the shape representation. It is shown that the increase in the average torque resulting from the proposed hybrid optimization is larger than that obtained by the conventional TO in which only the topology of the flux barrier is optimized. The decomposition of the total torque to the magnet and reluctance torques suggests that the reluctance torque is effectively generated in the rotor optimized by the proposed method.
