Description
Claims (1)
- 헤드드럼모터(1)의 로터(2)와 스테이터(3)측에 각각 형성되어 있는 브이씨알의 에프쥐센서회로에 있어서,상기 로터(2)의 원통형몸체의 회전원주상에 극성이 서로 다른 영구자석을 일정단위로 분할한 다음 일정갭(4)을 두고 이들을 착자시켜 형성되는 회전마그네트(5,5a-d)와, 이 회전마그네트(5)의 착자면에 대향해서 고정프린트기판(6)상에 원형의 펄스코일 형상으로 일정단위로 분할 배치된 검출패턴(7a-d)과,이 검출패턴(7a-d)의 출력단자에 각각 연결되어 분할된 검출패턴(7a-d)을 통해 검출되는 분할에프쥐 검출신호들을 각각 증폭하는 증폭기(8a-d)와, 이 증폭기(8a-d)로부터 각각 입력되는 분할에프쥐검출신호들을 가산하여 합산된 에프쥐검출신호로 출력하는 가산기(9a-9c)로 이루어지는 것을 특징으로 하는 브이씨알 헤드드럼모터의 에프쥐센서회로.
