两地均可以对电动机 M1 进行启动与停止控制，这样对于需要多地控制的场合就会非常合适，如果需要 3 地甚至更多地控制，只要按照左图一样， 在启动按钮侧并联更多启动按钮，在停止按钮侧串联更多停止按钮就可以。

三相异步电动机正反转控制原理分析

主回路采用两个接触器，即正转接触器KM1和反转接触器KM2。当接触器KM1的三对主触头接通时，三相电源的相序按U―V―W接入电动机。当接触器KM1的三对主触头断开，接触器KM2的三对主触头接通时，三相电源的相序按W―V―U接入电动机，电动机就向相反方向转动。电路要求接触器KM1和接触器KM2不能同时接通电源，否则它们的主触头将同时闭合，造成U、W两相电源短路。为此在KM1和KM2线圈各自支路中相互串联对方的一对辅助常闭触头，以保证接触器KM1和KM2不会同时接通电源，KM1和KM2的这两对辅助常闭触头在线路中所起的作用称为联锁或互锁作用，这两正向启动过程对辅助常闭触头就叫联锁或互锁触头。
