PROBLEM TO BE SOLVED: To provide a spindle motor for reducing the number of components by directly installing a suction magnet on a rotor cover, enhancing an yield, and preventing oil within a bearing from flowing to the outside without additional components by adjacently installing the suction magnet above the bearing. SOLUTION: The spindle motor 100 includes a rotating shaft 111, the rotor cover 121 coupled to the rotating shaft 111 and rotating the rotating shaft 111, the bearing 115 for rotatably supporting the rotating shaft 111, a holder 125 for supporting the bearing 115, and the suction magnet 141 directly installed on the inner wall of the rotor cover 121. The suction magnet 141 is installed and positioned above the bearing 115 so as to prevent the oil within the bearing 115 from flowing to the outside. COPYRIGHT: (C)2007,JPO&INPIT
