Disclosed is a heating, ventilation, air conditioning (HVAC) door actuator to rotate and operate a door opening/closing an air flow in an air-conditioner of a vehicle. According to the present invention, the HVAC door actuator comprises: a housing; a pin fixated and coupled to the inner surface of the housing; a motor including a stator disposed around the pin inside the housing and including a wound coil to be magnetized, and a rotor including a permanent magnet to be interfered and rotated by the magnetized stator; and at least one gear disposed inside the housing and transferring rotary power of the rotor to the door. The rotor has a pin through-hole into which the pin is inserted at the center and having a rotor core in which the permanent magnet is fixated to and supported from an outer circumferential part. The rotor core includes a plurality of pressing fingers to elastically press the outer circumferential surface of the pin.
차량용 공기 조화기에서 공기 흐름을 개폐하는 도어(door)를 회전 구동하는 HVAC 도어 액추에이터가 개시된다. 개시된 HVAC 도어 액추에이터는, 하우징, 하우징의 내측면에 고정 결합된 핀, 하우징 내부에서 핀 주변에 배치되며, 권선된 코일을 구비하여 자화되는 스테이터와, 핀에 회전 가능하게 결합되며, 영구자석을 구비하여 자화된 스테이터에 의해 간섭되어 회전하는 로터를 구비한 전동 모터, 및 하우징 내부에 배치되며, 로터의 회전력을 도어에 전달하는 적어도 하나의 기어를 구비한다. 로터는, 핀이 끼워지는 핀 관통공이 중앙에 형성되고, 외주부에 영구자석이 고정 지지된 로터 코어를 구비하고, 로터 코어는 핀의 외주면을 탄성 가압하는 복수의 가압 핑거를 구비한다.
