Abstract

본 발명은 윤활유의 비산을 방지함으로써 수명을 대폭 길게 하도록 한 스핀들 모터를 제공하는 것을 목적으로 한다.It is an object of the present invention to provide a spindle motor which greatly prolongs its life by preventing the lubricating oil from scattering.

고정 배치된 스테이터 기판(12), 스테이터 기판 상에 부착된 미끄럼 베어링(15), 이 미끄럼 베어링의 주위에 배치된 권선 코일(14)을 포함하는 스테이터부(11)와, 상기 미끄럼 베어링에 회전 가능하게 지지된 회전축(21), 상기 권선 코일에 대향하도록 회전축에 일체적으로 고착된 로터 요크(22), 로터 요크에 구비된 로터 마그넷(23)을 포함하는 로터부(20)로 구성되어 있는 스핀들 모터(10)에 있어서, 상기 미Rm럼 베어링의 적어도 한쪽 단부면에 윤활유 비산 방지용 플레이트(17)가 설치되어 있다.A stator part 11 including a stator substrate 12 fixedly disposed, a sliding bearing 15 attached to the stator substrate, a winding coil 14 disposed around the sliding bearing, and rotatable to the sliding bearing. Spindle consisting of a rotor shaft (20) including a rotating shaft (21) securely supported, a rotor yoke (22) integrally fixed to the rotating shaft to face the winding coil, and a rotor magnet (23) provided on the rotor yoke. In the motor 10, a lubricating oil splash preventing plate 17 is provided on at least one end surface of the micro Rm rum bearing.
