摘要

当转子在铝导轨上同时旋转和平移时，在气隙中产生一个时变磁场。这个磁场在导轨中产生涡流，同时产生悬浮和推进力或断裂力。采用一种新颖的基于二维解析的a - 方法，将转子场纳入导轨的边界条件中，对转子运动产生的场和力进行了建模。通过有限元分析验证了模型的精度。

A 2D analytic based model of a rotor moving over a conductive guideway

When a rotor is simultaneously rotated and translationally moved above an aluminum guideway a traveling time-varying magnetic field is created in the air-gap. This field induces eddy currents in the guideway that can simultaneously create suspension and propulsion or breaking forces. The field and forces created by this moving rotor are modeled using a novel 2D analytic based A-⌽ method in which the rotor field is incorporated into the boundary conditions of the guideway. The model accuracy is verified using finite element analysis.
