According to one embodiment of the present specification, a motor for a drone comprises a washer mechanically assembled between an upper surface of a lower screw and a lower surface of a lower bearing to maintain a necessary bearing preload during flight and simultaneously transfer thrust, and consistently and mechanically coupled with a shaft even when the lower screw is loosened to support the thrust. The washer may be formed in a cylindrical shape and may be mechanically assembled to a cutting part of the shaft by rotating the washer at 90 degrees in a clockwise direction or a counterclockwise direction after a flange part of the shaft is inserted through a flange part insertion hole formed on one side of the washer of the cylindrical shape in a longitudinal direction of the shaft.

    본 명세서의 일 실시 예에 따른 드론용 모터는, 하부 스크류의 상면과 하부 베어링의 하면 사이에 기구적으로 조립되어 비행 시 필요한 베어링 예압을 유지함과 동시에 추력을 전달하고 하부 스크류가 풀린 경우에도 샤프트와의 결합을 기구적으로 유지하여 추력을 지지하는 와셔를 포함한다. 상기 와셔는 원통 형상으로 형성될 수 있고, 샤프트의 길이 방향으로 원통 형상의 와셔의 한쪽 면에 형성된 플랜지부 삽입 구멍을 통해 샤프트의 플랜지부를 삽입한 후, 상기 와셔를 시계 방향 또는 반시계 방향으로 90도만큼 회전시키는 것에 의해 샤프트의 커팅부에 기구적으로 조립될 수 있다.
