摘要： A disk memory drive includes a brushless drive outer rotor motor having an internal space and a stator with windings. The outer rotor coaxially encircles the stator and a substantially cylindrical air gap is defined between the stator and the rotor. The rotor includes permanent magnets and a hub. A disk mounting section is provided on the hub for accommodating at least one storage disk positioned in a clean chamber, the mounting section being adapted to extend through a central aperture of the storage disk. The windings and the magnets interacting with the windings are disposed for at least half of the axial extension thereof within a space surrounded by the disk mounting section of the hub. Bearings rotatably mount the rotor and the hub.
