Abstract

In order to balance the torque density and utilization of permanent magnet (PM) material in large air gap rim-driven thruster (RDT), a three-segment Halbach array consequent-pole PM rim driven machine (HCPM-RDM) with unequal pole arc is proposed in this paper. In this design, the proposed HCPM-RDM can significantly reduce the PM volume, while taking advantage of the flux focusing effects of the Halbach structure, and improve the torque density. To satisfy the operating requirements of the RDT, a multi-objective stratified optimization design is conducted, in which the response surface (RS) coupled genetic algorithm (GA) and particle swarm optimization (PSO) algorithm are purposely utilized. Then, the electromagnetic performance of the HCPM, CPM, SPM machines is extensively compared, which include the cogging torque, electromagnetic torque, torque ripple, loss and efficiency. Finally, the RDM prototype is tested to verify the effectiveness of corresponding optimization design and finite element analysis (FEA).

轮辋驱动推力器的Halbach结果极永磁机床多目标优化设计

为了平衡大气隙环驱动推力器（RDT）中永磁材料的转矩密度和利用率，提出了一种不等极弧的三段式Halbach阵列结果极永磁环驱动机构（HCPM-RDM）。在本设计中，所提出的HCPM-RDM可以显著减小PM体积，同时利用Halbach结构的磁通聚焦效应，提高转矩密度。为满足RDT的运行要求，采用响应面（RS）耦合遗传算法（GA）和粒子群优化（PSO）算法进行多目标分层优化设计。然后，对HCPM、CPM、SPM电机的电磁性能进行了比较，包括齿槽转矩、电磁转矩、转矩脉动、损耗和效率。最后，对RDM原型进行了测试，验证了相应优化设计和有限元分析的有效性。
