本文对轴向磁通永磁电机（afpm）和径向磁通永磁电机（RFPMs）的热性能和电磁性能进行了全面比较。此外，由于没有任何研究小组研究过长径比对两种机器热特性的影响，因此本文重点研究了长径比对两种机器热特性的影响。最后，通过三维有限元分析和实验结果，研究了具有nd键合PM的平面afpm在工业应用中的有效性。
This paper provides comprehensive comparison including thermal and electromagnetic properties between axial-flux permanent magnet machines (AFPMs) and radial-flux permanent magnet machines (RFPMs). In addition, this paper focuses on influence of the aspect ratio on thermal characteristics of both machines because that have not been investigated in any research group. Finally, effectiveness of the proposed flat-AFPM having Nd-bonded PM for industrial applications is investigated and shown by 3D-FEA and experimental results.
