摘 要: In this paper a study of a 3D-coil model which is suitable for the analysis of bearing currents in converter-fed induction motors is presented. The coil model consists of one slot surrounded by a part of the stator yoke. The thin lamination of the yoke is scaled up spatially in the direction of current propagation in the slot for the simulations. The excitation is carried out by means of a sinusoidal current at different frequencies. In a second set of simulations, a voltage surge is considered as the excitation signal. The bearing current is evaluated in frequency domain as well as in time domain.

本文提出了一种适用于分析变流器供电感应电机中轴承电流的三维线圈模型。该线圈模型由一个槽体构成,其周围环绕着部分定子轭形结构。为进行仿真,将轭形薄片在槽内电流传播方向上进行了空间放大。激励信号采用不同频率的正弦电流实现。在第二组仿真中,考虑电压突波作为激励信号。轴承电流在频域和时域中均被计算评估。
