摘要

通过对表面永磁游标直线电机气隙磁通密度分布的计算和分析，设计并分析了表面永磁游标直线电机的特性。游标电机是一种具有磁齿轮效应的电动机，在低速时具有高转矩特性。本文首先详细介绍了SPMVLM的工作原理和气隙内的磁通密度。其次，根据永磁体厚度和定子槽开度比等设计参数，分析气隙内磁通密度的谐波;最后，确定了最佳设计参数，并用二维有限元法(FEM)验证了解析计算结果。

Design and Analysis of Surface Permanent Magnet Vernier Linear Motor Based on Air Gap Magnetic Flux Density Distribution

This paper aims to design and analyze the characteristics of a surface permanent magnet vernier linear motor (SPMVLM) by calculating and analyzing the air-gap magnetic flux density distribution. The vernier motor is a kind of electric motors with a magnetic gear effect and has high torque characteristics at low speeds. In this paper, firstly, the operational principle of the SPMVLM and the magnetic flux density in the air gap are described in detail. Secondly, the harmonics of the magnetic flux density in the air gap are analyzed according to the design parameters such as a permanent magnet thickness and stator slot opening ratio. Finally, the best design parameters are determined and the 2-dimension finite element method (FEM) results verify the analytical calculation results.
