摘要： A hydrodynamic bearing device which realizes power saving, reduction of a time period necessary for stabilizing rotation, and enhancement in durability to startup and halting of the motor at the same time by accelerating circulation of a lubricant in the vicinity of a flange with torque loss being kept low is provided. A flange (3) is fixed to one end of a shaft (2). On an inner surface of one of openings of a sleeve (1), a step portion (1C) is provided. When the shaft (2) is inserted into the sleeve (1), the flange (3) is in close vicinity to the step portion (1C). An inner diameter of the step portion (1C) is smaller in end portions in an axial direction than in a central portion. Thus, a gap between an outer surface (3C) of the flange (3) and a surface of the step portion (1C) which opposes the outer surface (3C) is narrow in the vicinity of boundaries of the outer surface (3C) of the flange (3) than in the vicinity the central portion.

摘要： A magnet (13) for trapping abraded powder is disposed in a connecting passage between an opening of a sleeve and an opening of a hydrodynamic bearing motor, and a shaft (3), a sleeve (4), a thrust flange (7), and a thrust main plate (5) are made of an austenitic stainless. With this configuration, since the austenitic stainless acting as a nonmagnetic substance is used, it is possible to increase a degree of cleaning. Further, abraded powder of the austenitic stainless is transformed into a magnetic substance, and thus a flow of the abraded powder to the outside can be prevented by providing the magnet for trapping abraded powder in the connecting passage between an opening of a bearing and the outside of the motor.

摘要： A gas dynamic bearing motor is provided that is capable of setting a bearing radius to a large value to obtain a sufficient radial stiffness, and preventing lock of the bearing and scattering of wear powder outside the bearing. An annular groove 11 is provided on a lower end surface 87 of a hub 3 to thereby enable a deformation of an inner circumferential surface 82 of the hub 3 when recording disks 9 are loaded on the hub 3 to be suppressed to a small value, thereby enabling partial contact in the radial bearing to be suppressed and lock of the bearing to be prevented. Further, a protrusion 12 is provided on a base 7 in a circumferential direction and fitted in the annular groove 11 to construct a labyrinth seal, thereby enabling scattering of wear powder generated on bearing surfaces outside the bearing to be prevented.
