牵引电动机反馈试验中的失控现象分析及调控方法

Analysis of incontrollable phenomenon and regulating method for traction motor feedback test

从电压和功率平衡关系的角度详细分析了牵引电动机反馈试验中的失控现象 ,其原因是各电机的磁场特性不尽相同 ,有的差异还相当大所致。因此 ,提出采用调磁的方法来消除或减小磁场的差异 。

The incontrollable phenomenon in traction motor test is analyzed in detail based on the relation of voltage balance and power balance. The reason is that magnetic field characteristics of motors are not all the same, and in some cases the differences are considerable .The method of regulating magnetic field is put forward to eliminate or minify the differences, thus the incontrollable phenomenon can be inhibited.
