Claims (5)
- 회전축;
상기 회전축의 주변에 배치된 코어에 권선 된 코일을 포함하는 고정자;
상기 회전축에 결합 된 요크 및 상기 코어와 마주하게 상기 요크의 내측면에 배치된 마그네트를 포함하는 회전자; 및
상기 요크의 상판 상에 배치되고 상기 회전자에 결합 되며 볼을 수납하는 홈이 형성된 턴 테이블을 포함하며,
상기 회전자 및 상기 턴 테이블의 진동을 저감 시키기 위해 상기 볼의 직경(Bd)에 대한 상기 요크의 외측면 반경(Yr)의 비율(Yr/Bd)은 4.6 내지 4.9인 스핀들 모터. - 제1항에 있어서,
상기 볼의 직경(Bd)에 대한 상기 요크의 외측면 반경(Yr)의 비율(Yr/Bd)은 4.72인 스핀들 모터. - 제1항에 있어서,
상기 볼의 직경(Bd)은 2.30mm 내지 2.40mm인 스핀들 모터. - 제3항에 있어서,
상기 볼의 직경(Bd)은 2.381mm인 스핀들 모터. - 제1항에 있어서,
상기 턴 테이블의 편심 감소에 따른 진동 저감을 위해서 상기 홈의 내측면들 중 원심력에 의하여 상기 볼과 접촉되는 바깥쪽 내측면의 반경은 상기 요크의 외측면 반경(Yr) 보다 작게 형성된 스핀들 모터.
