Abstract

회전정도가 향상되고 진동이 감소된 하드 디스크 드라이브의 스핀들모터에 관한 것으로, 고속으로 회전할 때 안정된 회전력을 얻을 수 있으며, 간단하고 빨리 조립할 수 있는 하드 디스크 드라이브의 스핀들모터를 제공하기 위하여, 스핀들모터의 중심축에 삽입되어 고정된 환형의 스러스트링과 중심축에 삽입되어 스러스트링 위에 위치하는 부시를 마련하고 부시에 회전자를 스러스트에 고정자를 연결하였다.Spindle motor of a hard disk drive with improved rotational accuracy and reduced vibration. To provide a stable rotational force when rotating at high speed, and to provide a simple and quick assembly spindle motor, the spindle motor An annular thrust ring inserted into the central axis of the shaft and a bush inserted into the central shaft were provided to connect the stator to the thruster.
