对磁耦合进行精确分析和优化设计对于最小化磁性材料的体积以及避免为实现给定设计目标而构建和测试多个模型至关重要。本文将三维和二维有限元分析（FEA）以及解析方法的结果与实验进行了比较。发现三维分析具有更好的一致性。讨论了三维和二维有限元分析网格的设计。提出了一种针对端部漏磁对二维有限元分析进行修正的方法。展示了结合计算机搜索技术使用三维有限元分析进行优化的过程。
Accurate analysis and optimal design of magnetic couplings are essential to minimise the volume of magnet material and to avoid the construction and testing of multiple models to achieve a given design goal. This paper compares the results of using 3D and 2D finite element analysis (FEA) and analytical methods with experiment. It is found that 3D analysis provides superior agreement. Design of FEA meshes in 3D and 2D are discussed. A method of correcting 2D FEA for end leakage is presented. Optimisation using 3D FEA, combined with computer search techniques, is demonstrated.
