电刷知识及试验一.电刷是用于换向器或滑环上作为导入导出电流的滑动接触体它的导电导热以及润滑性能良好 并具有一定的机械强度和换向性火花的本能几乎所有的直流电机以及换向式电机都使用电刷它是电机的重要组成部件广泛适用于各种交直流发电机同步电动机电瓶直流电动机吊车电机集电环各型电焊机等等 随着科学技术的发展电机的种类和使用的工况条件越来越多样化因

碳刷的作用碳刷的作用你要了解碳刷的作用你首先需要了解电能与动能转换的基本原理也就是要了解电机的原理发电的原理 是磁场切割导线后在导线产生电流发电机是采用让磁场旋转的方法切割导线的旋转磁场是转子被切割的导线是定子 为了让转子产生磁场必须向转子的线圈输入厉磁电流碳刷就是用来将厉磁发电机产生的厉磁电流送入转子线圈的 只有换向器或者滑环的电机里面才有碳刷普通的交流异步电动机是鼠笼结构没有碳刷电机就是电动机
