摘　　要：通过对某进口直流牵引电动机电刷压力随电刷磨耗程度不同而发生变化的计算和分析,得出电刷压力和电刷磨损间的非线性关系,确定该款进口电机电刷压力范围。Through the study and analysis on brush pressure variation corresponding to different wearing degree of the brush in an imported DC traction motor, nonlinear relationship between the brush pressure variation and brush wearing is achieved. Thus, ranges of brush pressure of the imported DC traction motor are settled.

关 键 词：直流牵引电动机 电刷压力 电刷磨耗
