摘要

本文提出了一种二维谐波建模（HM）方法，用于分析无轭分段电枢（YASA）轴向磁通电机铁芯的非线性磁导率。该方法利用复傅立叶级数和柯西积在柱坐标下建立麦克斯韦方程组，有效地解决了局部饱和效应。为了验证该模型的有效性，进行了三维有限元分析，结果与所提出的方法吻合较好。特别是，与传统的FEM模拟相比，HM方法将计算时间减少了30倍，使其成为需要3d分析的高价值应用中电机预设计和优化的有前途的工具。

Electromagnetic Analysis of YASA Axial Flux Motor Using Harmonic Modeling Considering Non-Linear Core Permeability

This study presents a 2-D harmonic modeling (HM) approach for analyzing the non-linear permeability of the core in a yokeless and segmented armature (YASA) axial flux motor. The proposed method formulates Maxwell’s equations in cylindrical coordinates using complex Fourier series and the Cauchy product, effectively addressing local saturation effects. To validate the model, a 3-D finite element method (FEM) analysis was conducted, demonstrating good agreement with the proposed approach. In particular, the HM approach reduces computational time by up to 30 times compared to conventional FEM simulations, making it a promising tool for motor pre-design and optimization in high-value applications that require 3-D analysis.
