摘要
电动机直接启动控制线路的常见故障有:按启动按钮后电动机不能启动;接通电源无须启动按钮控制,电动机自行运转;电动机启动运转后,手离开按钮电动机便停转;按下停机按钮,电动机不能停转,等等。本文阐述了Y-△降压启动控制线路的故障诊断与排除,自耦变压器降压启动线路的故障排除等问题。
the direct motor starting control circuit common fault are the main press the start button motor can not be started;the power supply is switched on without the start button control, motor bike;electric motor starts to work, the motor stops rotating hands off button; press the stop button, the motor can not stop etc.. This paper mainly introduces Y- reduced voltage starting control circuit fault diagnosis and elimination, autotransformer fault step-down start line to eliminate the problem.
