Provided is an aviation propeller motor capable of having a simplified structure by installing an encoder and a PCB for detecting the rotation speed of a rotor in a simple structure. To achieve the purpose, in accordance with the present invention, the aviation propeller motor includes: a rotor cover having a rotor magnet mounted on an inner circumferential surface and having one end in an axial direction opened; a bearing housing having a stator coil mounted on an outer circumferential surface to be opposed to the rotor magnet and having a bearing mounted on an inner circumferential surface; a rotating shaft coupled to the center of the other end of the rotor cover in the axial direction to penetrate the bearing housing, and coupled to the bearing housing to rotatable through the bearing to be rotated together with the rotor cover; an annular encoder coupled to the inside of the rotor cover to be rotated together with the rotor cover, and having a plurality of encoder magnetic parts formed on an outer circumferential surface along a circumferential direction; and a PCB coupled to one end of the bearing housing in the axial direction, and equipped with an encoder sensor for sensing the plurality of encoder magnetic parts.

    회전자의 회전속도를 검출하기 위한 엔코더 및 PCB를 간단한 구조로 설치하여 구조가 단순해진 항공용 프로펠러 모터가 제공된다. 이를 위해, 본 발명에 따른 항공용 프로펠러 모터는, 내주면에 회전자 마그네틱이 장착되고 축방향의 일단이 개구된 회전자 커버와, 상기 회전자 마그네틱과 대향되는 고정자 코일이 외주면에 장착되고 내주면에는 베어링이 장착되는 베어링 하우징과, 상기 회전자 커버의 축방향의 타단 중심에 결합되어 상기 베어링 하우징을 관통하고 상기 베어링을 통해 상기 베어링 하우징에 회전 가능하게 결합되어 상기 회전자 커버와 함께 회전되는 회전축과, 상기 회전자 커버의 내부에 결합되어 상기 회전자 커버와 함께 회전되고 외주면에 원주방향을 따라 복수개의 엔코더 마그네틱부가 형성된 환형의 엔코더와, 상기 베어링 하우징의 축방향 일단에 결합되고, 상기 복수개의 엔코더 마그네틱부를 감지하는 엔코더 센서가 장착된 PCB를 포함한다.
