ABSTRACT:
A compact outer-rotor electric motor that can be used for directly driving a disk for recording and reproducing information has an axially deep, tank-form flange and a stationary shaft, upon which the mounting annulus of the flange and the ball bearings of the hub are axially displaced. The hub includes a cover disk for sealing an extremity of the ball bearings and an inverted cup shape rotor providing magnetic shielding. The flange includes a mounting rim substantially aligned with the back surface of the cup-shape rotor. The facing cup-like and tank-form shapes readily enable labyrinth seals, comprising seals of the lower bearings.
