摘要

本文研究了电动汽车用轴向磁通永磁(AFPM)电机设计中二维和三维有限元模型的结合。首先，提出了一种适用于不同AFPM机器拓扑结构的二维有限元分析(FEA)设计工具，以便对各种设计进行快速评估。利用该工具分析了槽极组合对双定子-单转子结构的影响。其次，通过与三维有限元分析的比较，突出了该方法的精度水平和局限性。最后，对一个18槽/12极的AFPM电机进行了计算，并利用三维有限元分析加入了径向和切向磁体分割对涡流损耗的影响。

Combination of 2D and 3D Finite Element Models in the Design of Axial Flux Permanent Magnet Machines for Electric Vehicle Applications

This paper deals with the combination of 2D and 3D finite element models in the design of axial flux permanent magnet (AFPM) machines for electric vehicle application. First, a 2D finite element analysis (FEA) design tool suitable for different AFPM machines topologies is proposed giving access to a fast evaluation of various designs. The impact of the slot- pole combination on double stator-single rotor architecture is carried out using this tool. Secondly, the level of accuracy and limitations of this method are highlighted by a comparison with 3D FEA. Finally, a 18-slot/12-pole AFPM machine is calculated and the effect of magnet segmentation in radial and tangential directions on eddy current losses is added using 3D FEA.
