Soft-starter can limit the start current and torque of the induction-motor, reduce the influence to the power circuit in the starting process, and prolong electrical equipments' working life.

软启动器可以限制感应电机的起动电流及起动转矩，减少了电机起动过程中对电网的冲击，延长了电气设备和机械结构的使用寿命。

The results show that the soft starter could start up smoothly and reliably, and the starting current of the asynchronous motor is controlled.

结果表明，该软起动器在软起动过程中，限制了电动机的起动电流，实现了电动机的平稳起动。

It avoids the phenomena that some damage to motor and starter from other equipment can not trace the starting process of motor by overload.

起动控制由起动器根据电机的转速自动完成，彻底避免了其它起动装置不能根据负载的大小，自动跟踪电机起动过程而造成电机或起动器损坏等不良现象。
