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.
