电动机的软启动在家用电器中的应用

Applications of Motor Soft Start in Household Appliances

异步电机具有优良的性能和无需维护的特点,得到了广泛的应用。但是在启动过程中会产生比较大的冲击电流,而且它的启动应力比较大,从而降低负载设备的使用寿命。通过比较电动机传统的启动方式和软启动方式,从而得出了电动机软启动技术的优点,并分析了软启动技术的选择和应用。

The asynchronous motor has characteristics of excellent performance and maintenance free, which is of a wide range of applications. But it will produce a relatively large impact current in the startup process and the start stress is relatively large, thereby can reduce the loading equipment life. By comparing the traditional start mode and soft start mode of the motor, advantages of motor soft start technology can be obtained, and the selection and application of soft-start technology is analyzed.
