Abstract

스핀들모터에서 발생되는 진동 및 소음을 감소시킬 수 있는 스핀들모터에 관한 내용이 개시되어 있다. 이 스핀들모터는 고정부와 회전부 사이에 설치된 유체 베어링과, 이 유체 베어링과 회전부 사이에 설치된 적어도 하나의 링을 구비한다. 이 링이 스핀들모터의 유체 베어링에서 발생되는 진동을 감쇄시켜 회전부에 전달함에 따라 회전부에 설치된 회전체 예컨대 디스크는 정밀하고 안정되게 회전된다.Disclosed is a spindle motor capable of reducing vibrations and noise generated in the spindle motor. The spindle motor has a fluid bearing provided between the stationary part and the rotating part, and at least one ring provided between the fluid bearing and the rotating part. As this ring attenuates and transmits the vibration generated in the fluid bearing of the spindle motor, the rotating body, such as a disk, installed in the rotating part rotates precisely and stably.
