直流电机由于具有换向设备:换向器、电刷、刷握等装置,而增加了其检修保养的环节。特别电刷是活动的磨损部件,需要定期检查其活动间隙及磨损量,否则将引起换向不良,烧损换向器、主、附加极、电枢等,造成电机大修,后果相当严重。因此,直流电机的运用保养就显得更重要了。本文就是从ZQDR-410型牵引电动机的运用保养过程中存在和出现的问题入手,来分析其故障原因,并针对每一故障原因提出了实际可行的防止措施。
DC motor has a commutation device: commutator, brush, brush holder and other devices, and increased its maintenance links. Special brush is the activity of wear parts, the need to regularly check the activities of the gap and wear, otherwise it will cause a bad change, burning commutator, the main pole, armature, etc., resulting in motor overhaul, the consequences are serious. Therefore, the use of DC motor maintenance is even more important. This article is from ZQDR-410-type traction motor operation and maintenance of existing problems and start to analyze the causes of failure, and for each cause of the malfunction put forward practical and feasible measures to prevent.
