摘要
在电动工具的测试和使用中,机电能量转换时换向器短路、线圈烧毁、电气腐蚀、轴断裂等电机转子失效现象较为常见。分析各类失效现象的产生原因,避免和减少潜在失效的发生。
In the test and use of power tools, it’s very common to see the motor armature failure phenomenon of commutator shorted, winding burned, electrical corrosion, shaft broken when the electromechanical energy transforms. This article analyses the causes of various failure phenomenon, preventing and reducing the incidence of potential failure.
