摘要

本文提出了一种简单的轴向磁通永磁涡流耦合器三维解析建模方法。根据傅里叶级数的数学表达式和不同坐标方向上的积分变换，简化了繁琐的边界条件。通过分析贝塞尔函数的几个系数，推导出圆柱坐标系下拉普拉斯方程的通解，有效地降低了现有含贝塞尔函数模型的复杂性。得到了气隙中磁通密度的轴向、周向和径向分量。分析结果与有限元结果的对比验证了模型的准确性。

A Simple 3-D Analytical Modeling Method and Sensitivity Analysis for the Axial-Flux Permanent Magnet Eddy Current Coupler

A simple three-dimensional analytical modeling method for the axial-flux permanent magnet eddy current coupler is proposed in this paper. According to the mathematical expressions of the Fourier series and integral transformation in different coordinate directions, the cumbersome boundary conditions are simplified. The general solution of the Laplace equation in cylindrical coordinates is derived by analyzing several coefficients of the Bessel function, which effectively reduces the complexity of existing models containing Bessel functions. The axial, circumferential, and radial components of the magnetic flux density in the air gap are obtained. The comparison between analytical results and finite element results has validated the accuracy of the model.
