Abstract

본 발명은 베어링 하우징 내에서 이루어지는 오일유로 상에서 오일의 정체구간 없이 원활한 순환이 이루어질 수 있는 고속 회전용 스핀들 모터에 관한 것이다. 상기 스핀들 모터는 로터, 일단이 상기 로터와 결합되는 회전축, 내주부에 상기 회전축의 외주면을 회전 가능하게 지지하며, 외주면에 길이방향을 따라 적어도 하나의 오일 순환용 요홈을 가지며, 오일 함유 소결 금속으로 이루어지는 슬리브 베어링, 상기 슬리브 베어링을 수용하는 제1 요홈과 상기 제1 요홈의 중앙부에 회전축의 타단을 지지하는 제2 요홈을 구비하며 수지로 이루어지는 베어링하우징, 및 상기 제1 요홈의 바닥에 오일이 통과하는 다수의 가이드 홈을 형성하도록 상기 회전축을 중심으로 방사상으로 간격을 두고 돌출 형성되며, 상기 슬리브 베어링의 하단이 안착되는 다수의 돌기부를 포함하는 것을 특징으로 한다.
