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.

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： In a spindle motor in which teeth portions of a stator core formed by laminating magnetic plates are bent in order to increase the number of turns of the stator windings, a gap in the teeth portions between the magnetic plates is avoided and a precise attractive force adjustment becomes possible. The stator core is bent such that its teeth portions faces a surface of a rotor magnet at right angles, and the teeth portions and salient pole arm portions around which windings are wound are substantially parallel to each other. The salient pole arm portions locate approximately halfway between a lower surface of a hub and an upper surface of a base. Further, a thickness of a magnetic plate is set to be 0.5 to 0.9 times that of other portions.
