摘要

针对印刷电路板（PCB）定子轴向磁通永磁电机特点，提出一种新型拓扑Halbach永磁体阵列，设计并分析应用该永磁体阵列的PCB定子轴向磁通永磁电机。与传统无铁心轴向磁通永磁电机相比，在相同尺寸、同等永磁体用量下，该新型拓扑Halbach永磁体阵列PCB定子轴向磁通永磁电机具有更高气隙磁密及每极磁通，可获得更高空载反电势，同时有效降低漏磁，使气隙磁密更接近正弦波，提升了电机整体性能。有限元分析结果和样机对比实验验证了该新型拓扑Halbach永磁体阵列PCB定子电机的合理性和有效性，为PCB定子轴向磁通永磁电机设计提供了参考依据和工程应用价值。

Abstract

A novel topology Halbach permanent magnet array is proposed and applied to the design of a printed circuit board (PCB) axial flux permanent magnet (AFPM) motor. Compared with the traditional coreless AFPM motor

this novel topology for a Halbach permanent magnet array PCB stator AFPM motor has larger air-gap magnetic flux density and air-gap flux per pole. The magnetic flux leakage is effectively reduced

and the air-gap magnetic density is close to the sine wave. Results of the finite element analysis and prototype experiments verify the feasibility and effectiveness of the novel Halbach permanent magnet array PCB stator motor. A reference basis and practical value for the design of the PCB AFPM motor are provided.
