三相笼形异步电动机的直接启动
直接启动即是将电动机定子绕组直接连接到额定电压的电网上启动电动机，又称全压启动。直接启动的优点是所需设备少，启动方式简单，成本低。电动机直接启动的电流是正常运行的5-7倍。
三相笼形异步电动机的降压启动
对于大容量的电动机来说，一方面是提供电源和变压器容量很难满足电动机直接启动的条件，另一方面强大的启动电流冲击电网和电动机，影响电动机的使用寿命，对电网不利，所以大容量的电动机和不能直接启动的电动机都要采用降压启动。
降压启动方式是指在启动过程中降低其定子绕组端的外施电压，启动结束后，再将定子绕组的两端电压恢复到额定值。这种方法虽然能达到降低启动电压的目的，但启动转矩也减小很多，故此法一般只适用于电动机的空载或轻载启动。
定子串电阻或电抗器降压启动
三相笼形异步电动机启动时，在电动机定子电路串入电阻或电抗器，使加到电动机定子绕组端电压降低，减少了电动机上的启动电流。这种启动方式不受电动机定子绕组接法形式的限制，但由于启动电阻的存在，将使设备体积增大，电能损耗大。
Y/ 降压启动
对于正常运行为 形接法的三相交流异步电动机，若在启动时将其定子绕组接为Y形，会降低启动电压。在启动时，可以对其采用Y/ 降压启动方法，即在电动机启动过程中，将定子绕组接成Y形接法，启动过程结束后，再接成 形接法。启动简单，运行可靠，应用较广泛。但它只适应于正常运转时定子绕组为 接的电动机。
定子串自耦变压器降压启动
这种方法是利用自耦变压器将电源电压降低后再加到电动机定子绕组端，达到减小启动电流的目的。启动性能好，但线路相对较复杂，设备体积大。
