Abstract

본 발명은 에어컨의 송풍모터 제어장치에 관한 것으로, 종래에는 회전속도 조절이 않는 교류모터를 사용하고 입력전압의 변동에 대응하지 못하였으므로, 저전압 또는 과전압 인가시 모터의 손상이 우려되었다. 본 발명은 이를 감안하여 송풍모터를 직류모터로 설치하고, 입력전압의 변동을 감지하여 저전압 및 과전압시 약풍모드와 강풍모드에서 각각 송풍모터의 회전속도를 조절해줌으로써 모터의 손상을 방지하고 냉방능력을 향상시킬 수 있게 된다.Disclosure of Invention Technical Problem [5] The present invention relates to a fan motor control apparatus for an air conditioner, and an AC motor without a rotational speed control has been used and can not cope with fluctuations in input voltage. In consideration of this, the present invention provides a blower motor as a DC motor, detects fluctuations in the input voltage, and adjusts the rotational speed of the blower motor in the weak wind mode and the strong wind mode at the time of low voltage and overvoltage, Can be improved.
