摘要

本文提出了一种轴向磁场永磁（AFPM）机器拓扑结构，其中包括两个带分齿的定子和一个N-铁永磁排列的转子。该机器专为直驱电动汽车（EV）应用而设计，结构紧凑，扭矩密度高。本文全面概述了 AFFMPM 机器的拓扑结构和工作原理，重点探讨了其从轴向磁场齿轮的演变过程。利用三维有限元法（3D FEM），演示了所提出的 AFPM 机器的电磁特性。结果显示，与基线 AFPM 模型相比，其性能有了显著提高，扭矩提高了 108%，扭矩/PM 体积提高了 166%。为了证实分析结果，我们建造了 AFPM 原型机并进行了实验。

Design of an Axial-Field Flux-Modulated Permanent Magnet Machine for Electric Vehicles

This article proposes an axial-field permanent magnet (AFPM) machine topology, in which two stators with splitting teeth and a rotor with N-iron PM arrangement are included. Specifically designed for direct-drive electric vehicle (EV) applications, this machine boasts a compact structure and high torque density. This paper comprehensively outlines the topology and operation principles governing the AFFMPM machine, with a focused exploration of its evolution process from the axial-field magnetic gear. Utilizing the three-dimensional finite element method (3D FEM), the proposed AFPM machine's electromagnetic characteristics are demonstrated. The results reveal a remarkable enhancement compared to the baseline AFPM model, achieving a 108% increase in torque and a 166% improvement in torque/PM volume. The AFPM prototype is constructed and experimented to confirm the analysis.
