The asynchronous motor is extremely widespread applied in industry and agriculture production.The motor produces a bigger electric current when starting,as well as the electrical network can have a tremendous influence to system itself,also wastes the electrical energy.When the motor load is lower than the rated load 75%,the efficiency was lower,has created the energy waste.After the theoretical analysis,has designed one kind of motor intelligence energy conservation controller,uses in motor energy conservation soft-start and the movement protection.
