Description

一种油田用串励直流电动机
技术领域
本实用新型涉及一种直流电动机,尤其涉及一种油田用串励直流电动机。 
背景技术
现有油田用串励直流电动机主要作为油田的泥浆泵、转盘和绞车的电机,其包括机壳、转轴、转子、定子、碳刷、换向器、前端盖和后端盖;由于该串励直流电动机在使用时会产生电弧,环火很容易对换向器前端造成损害,由此缩短了油田用串励直流电动机的使用寿命。 
发明内容
针对上述缺点,本实用新型的目的在于提供一种能提高换向器耐电弧能力的油田用串励直流电动机。 
本实用新型的技术内容:一种油田用串励直流电动机,其包括机壳、转轴、转子、定子、碳刷、换向器、前端盖和后端盖;其特征在于:在换向器前端绕包有一层保护带。 
本实用新型与现有技术相比所具有的优点是:本实用新型是通过保护带可提高的换向器耐电弧能力及防潮能力,从而提高了油田用串励直流电动机的使用寿命。 
附图说明
图1为本实用新型的结构示意图。 
具体实施方式
如图1所示,一种油田用串励直流电动机,其包括机壳1、转轴2、转子3、定子4、碳刷5、换向器6、前端盖7和后端盖8;其特征在于:在换向器6前端绕包有一层保护带9。
