The spindle motor is provided to reduce the surface vibration of disc by removing the rotary deviation of the radial direction of the axis of rotation. The spindle motor comprises the bearing housing(120). The bearing(130) is fixed to the bearing housing. The axis of rotation(140) is inserted into the bearing. The stator(150) is arranged near the bearing housing. The rotor(160) is fixed to the axis of rotation. The rotor rotates with the stator. The skidding preventing means suppresses the axis of rotation aroung the inner surface of bearing. The resonance preventing means is the first aspiration magnet(171) fixed to the bearing housing. The first aspiration magnet inhales the axis of rotation to one side of bearing.
