In this paper, a 3D analytical model of permanent magnet (PM) and electromagnetic hybrid Halbach array electrodynamic suspension (EDS) system for a conductive plate is presented. When the hybrid Halbach array moves to cut the conductive plate, the 3D eddy current forces are derived using the second-order vector potential (SOVP) based on y-component of the source magnetic flux density, which is derived using the Biot–Savart law and surface current method. The accuracy of the derived equations is verified by a 3D finite-element analysis (FEA) model. Furthermore, the effects of the main characteristic parameters on the levitation force are analysed.

永磁体和电磁混合 Halbach 阵列电动悬挂系统的 3D 分析模型

在本文中，提出了用于导电板的永磁 (PM) 和电磁混合 Halbach 阵列电动悬架 (EDS) 系统的 3D 分析模型。当混合 Halbach 阵列移动以切割导电板时，3D 涡流力是使用基于源磁通密度的 y 分量的二阶矢量势 (SOVP) 推导出来的，这是使用 Biot-Savart 定律推导出来的和表面电流法。导出方程的准确性通过 3D 有限元分析 (FEA) 模型进行验证。此外，分析了主要特征参数对悬浮力的影响。
