笼型异步电机由于结构简单、控制方便、效率高等优点而被企业广泛地应用于机械设备的拖动中。


在实际使用中，电动机在起动或停止过程中还存在着一系列问题。全压起动时要产生较大的冲击电流（一般为额定电流Ie的5~8倍）。电动机容量越大，起动时冲击电流对电网及其负载冲击就越大，特别是大容量电机直接起动会对电网及其他负载造成干扰，甚至危害电网的安全运行；同时由于起动应力较大，使负载设备的使用寿命降低。在停机时，如果拖动系统突然失去转矩，靠系统的摩擦转矩克服系统的惯性滑行停车，也给拖动系统带来诸多问题。

解决办法有两个：一是增大配电容量；二是采用限制电机起动电流的起动设备。如果仅仅为起动电机而增大配电容量，从经济角度来说，显然不可取。为此，对低压大电机需要配备限制电机起动电流的起动设备，常用的有Y/Δ起动，自藕降压起动等方式来实现。这些方法虽然靠接触器切换电压实施启动降压，可以达到降低电流的目的，但没有从根本上解决起动瞬时电流尖峰冲击问题。起动转距基本固定不可调，起动过程中都存在二次冲击电流，对负载机械有冲击转距，且受电网波动的影响，一旦出现电网电压向下浮动，会造成电机堵转、起动过程接触器带载切换，易造成触点的拉弧、损坏等方面问题。严重时烧毁开关、电动机，影响电网其它设备运行。
