异步电动机节能与保护控制器的设计

The Design of Saving and Protecting Controller on Induction Motors

本系统针对经常工作于空载或轻载的异步电动机而设计,能自动调节空载或轻载时的功率因数,提高效率,节约电能;当电动机出现缺相、过载、短路等故障时能立即给予自动保护。

The system is designed for induction motors which works in idling or light load state. It can adjust the power factor automatically to save energy and protect the motor. It can also offer safeguard when the motor loses phase or works in overload and short circuit condition.
