摘　　要：AFPM是当前研究热点,本文将一种新型的凸极型Halbach永磁阵列应用于该电机中,阐述了其结构与优点。借助三维有限元软件建立初步的参数化模型,进一步联合Workbench与Optislang仿真,通过GA进行全局多目标优化得到最优设计方案。优化后的新型永磁体阵列与相同尺寸的常规Halbach结构相比,减少了永磁体用量,降低了电机生产成本,提高了单位永磁体产生的基波磁密幅值和气隙磁密波形的正弦性。在保证理想的气隙磁场磁密大小情况下加入价格低廉的软磁材料降低了电机成本,为轴向磁通永磁电机的设计提供一定的参考。AFPM is a research focus recently,in this paper,a new type of salient pole Halbach permanent magnet array was applied to the motor,and its structure and advantages were described.A preliminary parametric model was established with the help of 3D finite element software,and the simulation was further carried out by Workbench and Optislang,and the optimal design scheme was obtained by global multi-objective optimization through GA.Compared with the conventional Halbach structure of the same size,the optimized new permanent magnet array reduced the amount of permanent magnet,reduced the production cost of the motor,and improved the sine of the fundamental magnetic density amplitude and the air gap magnetic density waveform generated per unit of permanent magnet.In order to ensure the ideal air-gap magnetic field density,the cost of the motor was reduced by adding low-cost soft magnetic material,which provided a certain reference for the design of axial flux permanent magnet motor.
