Abstract

A mathematical model of a collector traction motor with independent excitation has been proposed in which eddy currents from the main and additional poles are separately taken into account. The results of computer simulations to determine the response of developed model to an abrupt change in the voltage across the anchor and when the anchor is powered by a pulse converter have been considered. The electromagnetic processes that occur in the traction motor have been examined in detail at rated and reduced current of main poles and at various speeds. The mechanism of the effect of eddy currents from additional poles on the magnetic flux of main poles of the machine, emf, and rate of rise of the anchor current has been analyzed. The factors directly affecting the degree of influence of eddy currents from additional poles on the electromagnetic processes in a traction motor have been determined. Conclusions have been drawn regarding the appropriateness of taking into account the phenomenon under consideration when simulating the operation of a traction electric drive.

分别考虑主极和附加极涡流的集电极牵引电动机的数学模型

摘要

已经提出了具有独立励磁的集电极牵引电动机的数学模型，其中分别考虑了来自主极和附加极的涡流。已经考虑了计算机仿真的结果，以确定已开发模型对锚固件两端电压突然变化以及锚固件由脉冲转换器供电时的响应。在主极额定电流和减小电流下以及在各种速度下，已经详细检查了牵引电机中发生的电磁过程。分析了来自附加磁极的涡流对电机主磁极的磁通量，电动势和锚固电流的上升速率的影响机理。已经确定了直接影响来自附加极的涡流对牵引电机的电磁过程的影响程度的因素。已经得出关于在模拟牵引电驱动器的操作时考虑所考虑的现象是否适当的结论。
