本文提出了一种具有两个参数的运动导体三维涡流分析方法。一个是坐标系的速度，另一个是规定电磁势的规范条件。得到了由这些参数引起的一般公式，并进行了数值实验。采用了边缘有限元和后向差分法。阐明了电势是由这两个参数决定的，分析导体在电接触中的滑动需要这两个参数之间的适当关系。当我们分析电机时，包括移动的导电部件，例如，感应电动机和轨道发射器。
The paper presents a variation of the 3D eddy current analysis for moving conductors with two parameters. One is the velocity of the coordinate systems and the other is the gauge conditions which specify the electromagnetic potentials. The general formulation due to these parameters is obtained and numerical experiments are carried out. The edge finite elements and the backward difference method are applied to the formulations. It is clarified that the potentials are determined by both of these parameters and that a proper relation between the parameters is required to analyze the conductors sliding in electrical contact. When we analyze electrical machines including moving conducting parts, for example, induction motors and rail launchers.
