Abstract

This paper investigates the torque characteristic and multi-objective optimisation (MOO) of the multi-layer flux-barrier less-rare-earth permanent magnet synchronous machine (MLFB-LRE-PMSM) used for the electric vehicles (EVs). This study explores the variation of torque characteristics with current angle under different winding current conditions, and thoroughly analyses the influence of permanent magnet (PM) structure parameters on reluctance torque, PM torque and the proportion of reluctance torque in the electromagnetic torque. On this basis, the sensitivity analysis method based on Sobol sequence and joint Sobol index is adopted, which not only simplifies the traditional analysis process, but also effectively considers the interaction effect between the optimisation objectives. Finally, a cooperative optimisation strategy of improved whale optimisation algorithm (WOA) and genetic algorithm (GA) is proposed, which is successfully applied to the MOO design of MLFB-LRE-PMSM. The results show that the improved WOA algorithm shows excellent optimisation performance and can be used as a new solution in the field of motor optimisation. At the same time, the engineering practicability of the proposed collaborative optimisation scheme is verified by finite element simulation.

多层磁障无稀土永磁同步电机转矩特性分析及多目标优化
研究了用于电动汽车的多层磁障无稀土永磁同步电机(MLFB-LRE-PMSM)的转矩特性及多目标优化。研究了不同绕组电流条件下转矩特性随电流角的变化规律,深入分析了永磁结构参数对磁阻转矩、永磁转矩及磁阻转矩占电磁转矩比例的影响。在此基础上,采用基于Sobol序列和联合Sobol指数的敏感性分析方法,不仅简化了传统的分析过程,而且有效地考虑了优化目标之间的交互效应。最后,提出了一种改进鲸鱼优化算法(WOA)和遗传算法(GA)的协同优化策略,并将其成功应用于MLFB-LRE-PMSM的MOO设计中。结果表明,改进的WOA算法具有良好的优化性能,可作为电机优化领域的一种新的解决方案。同时,通过有限元仿真验证了所提协同优化方案的工程实用性。
