一般的降压启动是用原电压的60%左右，同星角启动电压基本一致。220v理想启动电压。
一般0.45X380
自耦变压器降压启动是指电动机启动时利用自耦变压器来降低加在电动机定子绕组上的启动电压。待电动机启动后，再使电动机与自耦变压器脱离，从而在全压下正常运动。这种降压启动分为手动控制和自动控制两种。
电动机自耦变压器降压的启动方式在电动机的线圈上引出多个抽头，不同的抽头接上电源后原副线圈的匝数比不一样，接通电源后电压也不一样，电机对电网电压的冲击也不一样，通过自耦降压启动，可以有效地保护电网电压不至于在瞬间变得很低从而保护电网中的其他设备，保证设备正常运行与生产连续进行。
自耦变压器进线侧标有百分百的抽头接起动接触器电源，抽头电压根据启动负载的大小决定，一般提供80%和60%两种。也就是提供300V和220V两种启动电压。
