【Abstract】 A soft starting controller of the asynchronous motor based upon STC microprocessor was proposed and the operational principle of the controller, functional block diagram was given. On the premise of effective reduction of starting current the controller has many optional functions, such as softstopping, energy saving operation, real time monitoring and safeguarding, to realize smooth and reliable start of different loads.更多还原
