推导了一个基于二维解析的导电板涡流瞬态模型，该模型能够考虑输入条件的连续变化。只需知道导电板表面的源场。此外，一个2-D的稳态分析为基础的涡流模型，是能够占在两个方向上的频率和速度的变化。这两种基于解析的模型都已使用有限元程序进行了验证。瞬态和稳态模型被集成到一个机电系统中的磁源是一个海尔贝克转子。比较了两种计算方法的精度。利用稳态模型导出了刚度系数和阻尼系数。
A 2-D analytic based eddy-current transient model for a conducting plate is derived that is capable of accounting for continuous changes in the input conditions. Only the source fleld on the surface of the conducting plate needs to be known. In addition, a 2-D steady-state analytic based eddy-current model that is capable of accounting for frequency and velocity changes in two directions is derived. Both analytic based models have been validated using flnite element code. The transient and steady-state models are integrated into an electromechanical system where the magnetic source is a Halbach rotor. The accuracy of both calculation methods is compared. The stifiness and damping coe-cients are derived using the steady- state model.
