DEVICE AND METHOD FOR CONTROLLING A SINGLE PHASE INDUCTION MOTOR CAPABLE OF STABLY OPERATING A MOTOR AT A LOW VOLTAGE REGION AND PROTECTING THE MOTOR FROM AN OVER VOLTAGE
DEVICE AND METHOD FOR CONTROLLING A SINGLE PHASE INDUCTION MOTOR CAPABLE OF STABLY OPERATING A MOTOR AT A LOW VOLTAGE REGION AND PROTECTING THE MOTOR FROM AN OVER VOLTAGE
PURPOSE: A device and method for controlling a single phase induction motor are provided to reduce manufacturing costs by starting or operating a motor with a simple circuit including a switch without a PCT thermistor or an overload protection device.;CONSTITUTION: Power is applied to a single phase induction motor through a main winding switch and a sub winding switch. A voltage applied to the single phase induction motor is detected(S120). A starting time is calculated based on the detected voltage(S130). If the starting time elapses(S150), the single phase induction motor operates by switching the main winding switch or sub winding switch(S161,S162).;COPYRIGHT KIPO 2011
