Abstract: Provided is a hydrodynamic bearing motor with an improved structure to stably prevent oil leakage from a bearing unit due to the centrifugal force generated during the rotation of the motor. The motor includes an oil gap formed between a rotor and a fixing body to form a hydrodynamic bearing to rotatably support the rotor. The fixing body includes a base to which a stator is fixed; and a hollow sleeve which is fixed at a center of the sleeve and in which a flange is formed in the upper portion thereof. The rotor includes a shaft, a hub to which the rotor is fixed, and a seal cover. Also, the motor includes a first taper seal which is gradually thinner in the direction of the centrifugal force to be linearly connected with the thrust bearingand formed between the bottom surface of a flange and the upper surface of the seal cover. Thus, oil leakage can be effectively prevented since oil in the taper seal is moved in the direction of the centrifugal force during the rotation of the hub and directed toward a thrust bearing.

Abstract: A disk drive unit for a disk, e.g. for use in a mobile device, comprises a spindle (1) positioned within the disk drive unit and adapted to support the disk rotatably in an operating position. An electric motor (2) is operatively coupled to the spindle (1) to rotate it. An auxiliary electric motor (3) is connectable to the spindle to accelerate the spindle during start-up. This auxiliary motor can be selected to work efficiently at zero speed. The electric motor may be a low-power motor, resulting in a reduced power consumption.
