Abstract
본 발명은 전자동 세탁기의 전기적 제동방법에 관한 것으로서, 특히 역상제동방식 즉, 모터 인가전압의 위상을 보상해주는 방법으로 모터를 제어하여 모터가 고속으로 회전할 때에는 큰 제동력을 갖고, 모터가 저속으로 회전할 때에는 자연스럽게 모터를 정지시킬 수 있는 전자동 세탁기의 전기적 제동방법에 관한 것이다.The present invention relates to a method of electric braking of a fully automatic washing machine. In particular, a reverse braking method, ie, a method of compensating the phase of a motor applied voltage, controls a motor to have a large braking force when the motor rotates at high speed, and the motor rotates at a low speed. When it is related to the electrical braking method of the automatic washing machine that can stop the motor naturally.
종래 전자동 세탁기의 제동방법은 모터제어를 위한 제어부에 모터구동 전용소자인 모터 구동부를 사용하기 때문에 발전제동방식에 의해 모터를 제어하고 따라서, 탈수 중 정전이 되었을 때 제어전원이 유지되지 못함으로 제동력이 사라지는 문제점이 있었다.The conventional braking method of a fully automatic washing machine uses a motor driving unit, which is a motor driving only element, to control the motor. Therefore, the motor is controlled by the power generation braking method. Therefore, the braking force is not maintained because the control power is not maintained when a power failure occurs during dehydration. There was a problem disappearing.
또한, 발전제어방식에 의해 발생하는 모터전류는 모터의 회전수(RPM)에 비례하기 때문에 고속회전하는 모터를 제동할 때 과도한 전류가 흘러 인버터회로가 파손되는 문제점이 있었다.In addition, since the motor current generated by the power generation control method is proportional to the rotational speed (RPM) of the motor, excessive current flows when braking the motor rotating at high speed, causing the inverter circuit to be damaged.
따라서, 본 발명은 상기 문제점을 해결하기 위해 역상제동방식 즉, 모터 인가전압의 위상을 보상해주는 방법으로 모터를 제어하여 모터가 고속으로 회전할 때에는 큰 제동력을 갖고, 모터가 저속으로 회전할 때에는 자연스럽게 모터를 중지시킬 수 있도록 한 전자동 세탁기의 전기적 제동방법이다.Accordingly, the present invention has a large braking force when the motor rotates at a high speed by controlling the motor in a reverse phase braking method, that is, a method of compensating the phase of the motor applied voltage to solve the above problems, and naturally when the motor rotates at a low speed. It is an electrical braking method of a fully automatic washing machine that can stop a motor.
