Abstract

본 발명은 코깅 토오그가 감쇠된 모터에 관한 것으로 모터의 아마츄어 회전시 급속한 자속변화에 따른 코팅토오크를 저감시키기 위하여 N극과 S극을 띤 마그넷(2)사이의 중성대(4)에 연자성체의 보조극(5)을 끼움으로써 자속의 변화를 완만하게 한 것이다.
따라서 급속한 자속변화에 의한 코팅 토오크를 감쇠시키는 동시에 마그넷(2)을 견고하게 지지할 수 있는 것이다.

Description

코깅토오크를 저감한 모터
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제3도는 본 발명의 모터 단면을 나타낸 구성단면도,
제4도는 본 발명의 마그넷과 아마츄어 사이에 보조극을 끼운 상태와 이에 따른 자화곡선을 나타낸 구성도와 그래프도이다.

Claims (1)

  1. N,S극을 갖는 마그넷(2)이 요크(1)에 고정되고 마그넷(2)내에 아마츄어 (3)가 베어링에 지지되어 회전되게 이루는 모터에 있어서, 마그넷(2)과 마그넷(2')사이의 중성대(4)에 연자성체의 보조극(5)을 삽입시킨 것을 특징으로 하는 코깅 토오크를 저감한 모터.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
