Abstract

단상 브러시리스 모터라도 특별히 고가의 자기동 처리수단을 설치하지 않아도, 모터의 구성요소의 일부를 개량하는 것만으로, 자기동 회전할 수 있는 것으로하며 사점위치에서 상기 계자 마그네트의 2분의 1자극 떨어진 각도 범위이내 위치에 있어서 스테이터 요크의 일부를 잘라 세우고, 잘라 세운조각을 형성하고 해당 잘라세운 조각에 의하여 상기 계자 마그네트가 사점 위치에서 구속되지 않는 것으로 하기 위하여 사점 탈출 토프크 발생용의 릴럭턴스를 얻는다.Even in the case of a single-phase brushless motor, it is possible to rotate magnetically simply by improving a part of the components of the motor without having to install a specially expensive magnetic moving processing means. A part of the stator yoke is cut out in an angular range, a cut piece is formed, and reluctance for generating dead spot escape torque is obtained so that the field magnet is not restrained at the dead spot position by the cut piece. .
