By studying on the motor' s economical running conditions, the paper proposes the control proposal that the Single - chip Microcomputer 89C52 is the control heart, the motor' s power factor is tested in real time and the voltage of stator is adjusted according to the change of motor' s load. Though the proposal carried out,the power factor is improved and the electric energy is saved. Meanwhile the paper explained the controller' s software and hardware principles. Controlling the motor by using the proposal can monitor the motor in all domains, such as starting, over -load, power cut and not enough voltage, etc.
