摘要： A disk drive includes a disk drive base, a spindle motor, a first disk and a disk clamp. The rotary hub of the spindle motor includes a generally cylindrically-shaped hub wall and a hub flange including an inner annular surface adjacent to the hub wall, an outer annular surface and a flange land portion integrally formed with the hub flange. The land portion is positioned between the annular surfaces and defines a disk contact surface projecting above the annular surfaces, the disk contact surface being substantially centered on the hub flange. The first disk is supported by the disk contact surface to form a clearance between the annular surfaces and the first disk. A second disk may be coupled to the spindle motor and an annular disk spacer may be positioned between the disks. The annular disk spacer includes a first spacer surface facing the first disk and a second spacer surface facing the second disk. The first and second spacer surfaces each comprise an inner annular spacer surface adjacent to the hub wall, an outer annular spacer and a spacer land portion integrally formed with the spacer and positioned between the annular spacer surfaces to define a spacer-to-disk contact surface that projects from the annular spacer surfaces to form a clearance between a respective disk and respective annular surfaces. The disk clamp for applies a clamping force to the first and second disks that is substantially centered on each spacer-to-disk contact surface and on the disk contact surface.

摘要： A brushless permanent-magnet direct current motor has a permanent magnet which is magnetized to create an offset angle between detent and mutual torques for providing sufficient starting torque for all relative orientations between the stator and the rotor of the motor. This is accomplished by providing a permanent magnet in which the global magnetization of the magnet has been disrupted by the application of a local magnetic field to a portion of the magnet, thereby to provide a magnetic anomaly in the global magnetization. Also, a method of magnetization of the magnet is described.

The stator base assembly is extended toward the first magnetized region to provide axial pre-load for the motor. The electromagnet poles further include a steel bobbin for increased flux density and added axial stiffness. Finally, eddy current generation means are disposed between the stator base and the like aligned single pole for improved dampening characteristics.
