摘要： A magnetic disk drive apparatus including: a hub being rotatably supported by bearings mounted on a center fixed shaft and driving magnetic disks while having the magnetic disks attached to the outer circumferential surface thereof; a drive magnet fixedly secured to the hub; and a stator core fixed on a frame portion so as to confront the drive magnet. A clamp cap portion on a distal end portion of the hub is arranged for closing a center hole of the hub, and a tap hole is formed at the center of the clamp cap portion so that a disk clamp for clamping the magnetic disks can be screwed.

摘要： A magnetic disc driving motor comprises a hub for mounting a magnetic disc thereon, a motor stator for driving the hub rotationally, and a motor rotor formed in the hub and arranged to face the stator at a predetermined gap. A support is provided for supporting a bearing member for bearing the hub rotatably. A stator supporting portion is formed integrally with the support for supporting the stator. A motor frame is formed to cover the stator and the rotor. The motor frame is formed of a thin sheet. The motor frame is fixed to the motor frame by a mechanical device or an adhesive. Another similar motor arrangement includes a hub with a rotatable central shaft. In this arrangement, the frame, stator support and bottom seal for the bearings are formed of a thin sheet. The stator support is a U-shape which is force fit into a recess between the bearing holder and coil of the motor.
