Claims (2)
- N,S의 자극을 교호로된 2P(P는 1이상의 정수)에 갖춘 계자 마그넷(2)을 회전자로서 구비하고, 이 계자 마그넷에 면 대향하는 고정측 위치에, 발생 토크에 기여한 도체부(4a,4'a)의 개각이 상기 계자 마그넷의 자극폭과 대체로 같은 폭으로 형성된 공심형 전기자 코일(4-1,4-2)과, 상기 계자마그넷의 자극폭과 대체로 같은 폭의 자기저항 발생용 자성체(25) 및 위치 검지소자(24)를 배설하고, 상기 자기저항 발생용 자성체는 그 중심선이 상기 전기자 코일의 발생 토크에 기여할 도체부에서 상기 계자 마그넷의 자극이 약4분의 3자극폭 만큼 떨어진 위치에 배설한 것에 있어서, 자기저항 발생용 자성체(25)는 회전자의 회전방향과 반대방향에 향하여 체적 혹은 면적을 서서히 감소시킨 형태로 구성한 것을 특징으로 하는 1상 통전하는 디스크형 브러시리스 모터.
- 제1항에 있어서, 자기저항 발생용 자성체는 회전 방향을 향하여 앞 위치의 단부(25a)에 테이퍼(28)를 형성함을 특징으로하는 1상 통전되는 디스크형 브러시리스 모터.
