    摘要： The invention relates to the spindle motor for driving a hard disk drive, comprising: a stationary motor component (10, 12, 16, 18), a rotary motor component (14) rotatably mounted relative to the stationary motor component using a fluid dynamic bearing system, a bearing gap (20) disposed between the stationary motor component and the rotary motor component and filled with a bearing fluid, having at least one open end, at least one sealing gap (34) for sealing the open end, at least one cover cap (30) for covering the sealing gap, which is secured to the rotatable motor component, a disk clamp (44) for attachment of at least one magnetic storage disk (48) on the rotatable motor member and an electromagnetic drive system (40, 42) to drive the rotatable motor member. The disk clamp (44, 156) is centered on a peripheral surface of the cover cap (30, 118).

    摘要： A spindle motor includes a recording disk and a clamper. A cylindrical portion includes a first screw portion positioned in an outer circumferential portion of the cylindrical portion. The clamper includes an annular raised portion configured to be fitted in a through hole of the recording disk. An inner circumferential portion of the clamper includes a second screw portion configured to be screwed to the first screw portion. At least a portion of the second screw portion is positioned in an inner circumferential portion of the annular raised portion. Each of the first screw portion and the second screw portion includes at least one of a screw groove and a screw thread. An axial position of at least a portion of the second screw portion overlaps with an axial position of the recording disk.
