摘　　要：为了提高集成式起动-发电机(ISG)的输出特性,降低电机成本,利用Halbach阵列永磁体理论,结合盘式电机三层叠式绕组技术,提出非均匀极弧长度Halbach盘式无铁心永磁ISG电机。首先,分析了电机结构及特点和电磁场计算过程。其次,以电机气隙磁场分布作为设计指标,利用三维有限元分析软件对电机的永磁体极弧比例、电枢直径比、转子轭部厚度等结构参数进行参数化优选。与预估结构参数对比表明:优选后电机永磁体主副磁极比例为5∶2∶1∶2时,气隙磁密基波幅值提高了9.72%。三层叠式绕组可增加线圈有效边长度,提高气隙磁场利用率,感应电动势平均值增加了8%。In order to improve the output characteristics and reduce the cost of integrated starter and generator( ISG),a non-uniform magnetic pole Halbach disc coreless permanent magnet integrated starter and generator was presented based on Halbach array permanent magnet theory and the three layers winding technology.Firstly,the structure and characteristics of ISG,and the calculation process of the electromagnetic field were analyzed. Secondly,taking the air gap magnetic field distribution as design goal,the three-dimensional finite element analysis software was used to optimize the structural parameters including the permanent magnet pole arc ratio,armature diameter ratio and yoke thickness of rotor. The results show that compared with the forecast structural parameters,the proportion of the primary and secondary magnetic poles of the permanent magnet is5∶ 2∶ 1∶ 2,and the fundamental magnetic density of the air-gap is increased by 9. 72%. Three layers winding is not only increase the effective length of side coil,but also improve the utilization rate of the air gap magnetic field. The overage value of the induced electromotive force is increased by 8%.
