LOW-PROFILE DISK DRIVE MOTOR |
摘要 |
A disk drive motor having a low profile construction and a gas-lubricated deflecting pad support usable in the disk drive motor and elsewhere includes a cup-shaped rotor having an integral cylindrical portion extending from the base of the cup; the cylindrical extension may be a shaft or a large hollow extension which encloses the stator windings. The stator can be conventional or can have a closed end and/or a cup-like portion to simplify construction and eliminate the need for a seal. A support mounted on the stator or the rotor supports the rotor for rotation relative to the stator. The support can be a deflecting pad support such as a deflecting pad hydrodynamic bearing or the plane or gas-lubricated deflecting pad support disclosed herein. The gas-lubricated deflecting pad support member includes bearing pads and a support structure which supports the bearings for strictly radial movement. A contoured surface is formed on the pad surfaces or a support surface opposing the pad surfaces or both. Relative rotation between the pad surfaces and the support surface results in the development of a pressurized gas film between the support surface and the pad surface. |
