METHOD FOR STARTING AND DRIVING A SINGLE PHASE AC INDUCTION MOTOR AND A CONTROL DEVICE FOR IMPLEMENTING THE SAME

摘要

PURPOSE: A method for starting and driving a single phase AC induction motor and a control device for implementing the same are provided to increase the lifetime of the motor by obtaining rotation force with a principle of a two-phase AC induction motor.;CONSTITUTION: Half-wave electricity is rectified to a diode(D1). The half-wave electricity is charged in a capacitor(C1). The electricity forms a sine wave alternating current. An FET(Field Effect Transistor)(F1) receives a control signal from PWM(Pulse Width Modulation). A voltage of a circuit receives a single phase AC voltage.;COPYRIGHT KIPO 2013;[Reference numerals] (AA) Power supply; (BB) Main coil; (CC) Starting coil; (DD) Single phase induction motor; (EE) Control unit; (FF) Condenser; (GG) Diode; (HH) Transformer; (II) Converter
