摘要
根据某起动直流电动机在外场实际工作过程中,由于电动机起动完成后,仍由发动机拖动空转,其电刷仍正常磨损,影响了电刷正常使用寿命,使得电动机在工作300小时后电刷高度不能满足正常工作的需要。因此,本文提出改变起动直流电动机的电刷高度来满足500小时更换一次电刷的要求。根据计算和分析,验证该调整方法的可行性。
Basis X start direct current electromotor is practical work process in outfield, the electromotor was dragged idle by the engine after the electromotor starts bring to success that it cause the electromotor＇s electrics brush still to wear has affected electrics brush normal service life, the electrics brush not to be able to satisfy the normal work highly the need after the electromotor operate 300 hours. Therefore, this article proposes changing the starting height of the electromotor electrics brush satisfies with 500 hours to replace a time require of electrics brush, according to the calculation and analysis verify the feasibility of this adjust method.
