Abstract
본 발명은 콘덴서 기동형 단상 유도전동기의 속도 제어방법에 관한것으로, 종래에는 모터의 속도를 변환하기 위해서는 외부 탭(Tap)에 의해 행해지는데, 이럴경우 외부 탭을 바꾸어주는 변환장치가 있어야 되고, 부하가 조금만 필요한 경우에도 필요이상속도로 회전함으로써 전력이 많이 소모되는 문제점이 발생되는바.The present invention relates to a speed control method of a condenser starting type single-phase induction motor, which is conventionally performed by an external tap in order to change the speed of a motor. Even if you only need a little bit by rotating at a higher speed than a lot of power consumption problem occurs.
본 발명에 의하면 입력상태에 따라 극수변환 명령을 출력하는 제어부(10)에 의해 릴레이부(40)에서 모터(30)의 극을 결정해주고, 전원을 입력하면 속도는 주파수를 변환시켜 속도를 제어할수 있게된것으로, 가전제품이나 산업분야에서 폭넓게 활용할수 있게된 발명인 것이다.According to the present invention, the relay unit 40 determines the pole of the motor 30 by the control unit 10 outputting the pole number conversion command according to the input state, and when the power is input, the speed can be controlled by converting the frequency. It is an invention that can be widely used in home appliances and industrial fields.
