Abstract
본 발명은 드럼세탁기에 있어서, 직류모터의 구동전압 및 분당 회전수의 변화상태를 판별하고, 모터회전을 원활하게 할수 있는 드럼세탁기의 직류모터 제어방법에 관한것으로써 모터의 회전을 정밀하게 제어할 수 있도록 모터의 rpm 변화에 따라 일정갯수의 구간으로 크게 구분하고 각각의 구간을 재차 일정갯수의 구간으로 재 구분설정해 놓은 상태에서, 모터의 현재 rpm과 마이콤에 설정된 모터인가전압에 대응하는 선택 rpm과의 차를 판별하고, 이 판별결과 현재 rpm이 선택 rpm보다 많을 경우에는 모터에 인가되는 전압을 서서히 감소시켜서 모터 현재 rpm이 선택 rpm에 도달토록하고, 현재 rpm이 선택 rpm보다 적을 경우에는 모터에 인가되는 전압을 서서히 증가 시켜서 모터의 현재 rpm이 선택 rpm에 도달토록 하는 직류모터의 구동제어방법에 있어서, 선택 rpm이 모터의 현재 rpm보다 클 경우 모터에 인가되는 구동전압을 단시간내에 급격하게 감소시켜서 모터인가전압과 이에 대응하는 rpm과의 지연현상을 보상토록 하는 것을 특징으로 한다.The present invention relates to a DC washing machine control method of a drum washing machine which can determine a change state of a DC motor's driving voltage and revolutions per minute, and which can smoothly rotate the motor, and precisely control the rotation of the motor. According to the rpm change of the motor, it is divided into a certain number of sections and each section is re-divided into a certain number of sections, and the selected rpm corresponding to the current rpm of the motor and the motor applied voltage set in the microcomputer If the current rpm is greater than the selected rpm, the voltage applied to the motor is gradually decreased so that the motor current rpm reaches the selected rpm, and if the current rpm is less than the selected rpm, the motor is applied to the motor. In the drive control method of a DC motor in which the current rpm of the motor is gradually increased to reach the selection rpm, the selection rp When m is greater than the current rpm of the motor, the driving voltage applied to the motor is rapidly reduced in a short time to compensate for the delay phenomenon between the motor applied voltage and the corresponding rpm.
