ABSTRACT:
A disc drive assembly includes a brushless direct current drive motor having a stationary shaft and a hub rotatably mounted about the stationary shaft by upper and lower bearings. The hub includes an interior space for housing a stator which has magnetically active parts for magnetic interaction with a permanent magnet mounted on an inner surface of the hub. The brushless drive motor is releasably mounted on a disc drive base member having a centrally located boss. The boss cooperates with a lower surface of a stator support for maintaining the stator of the drive motor in spaced relation with respect to the disc drive base member so that a printed circuit connector may be disposed between the stator and the disc drive base member proximate the stator winding. The subject invention also includes a labyrinth seal in combination with a ferrofluidic seal to prevent contaminant particles generated by the bearings and other internal parts of the drive motor from escaping into a contaminant-free disc storage environment.
