    摘要： Motors having a magnetic force attenuator are described. In some embodiments, the motors comprise a stationary member having a base and a stator, a rotating assembly having a magnet and a magnetic force attenuator to attenuate the magnetic attraction force between the magnet and the base; and a fluid bearing to support rotation of the rotating assembly relative to the stationary member. The magnetic force attenuator typically comprises a material of high magnetic permeability, and modulates the magnetic attraction force between the magnet and the base of the motor.

    摘要： A fluid dynamic bearing motor features a stationary assembly, a rotating assembly supported on the stationary assembly, a fluid dynamic bearing system in a gap between the stationary and rotating assemblies, a radial capillary seal defined proximate a first end of the journal gap, and at least one re-circulation hole extending from the radial capillary seal to a second end of the journal gap. A single thrust shaft end bearing which pressurizes the shaft end to create an axial thrust bearing and drive bubbles in the fluid (where the fluid is a liquid) to the outer diameter of the shaft and into the recirculation path. The journal may be supported for rotation by dual sets of grooves; the dual groove asymmetry in the journal maintains a positive pressure between the journals.

    摘要： An active fluid bearing system is provided. In one example, the active fluid bearing system includes an interface region formed between an outer surface of an inner member and an opposing inner surface of an outer member. The inner and outer members are disposed for relative rotation of the inner and outer members, and thereby form an interface region having a hydrodynamic bearing region and an active bearing region. A liquid is disposed in the interface region at the hydrodynamic bearing region, and is further disposed in the active bearing region if the inner and outer members are not relatively rotating. The bearing system is operable for evacuating at least a portion of the liquid from the active bearing region during relative rotation of the inner and outer members. The active bearing region may be a journal bearing or a thrust bearing.

    摘要： According to one example, a motor including a fluid dynamic bearing system is provided. The motor includes a first stationary member and a second member disposed for relative rotation and a fluid dynamic bearing region disposed therebetween. A stator is disposed with the first member and includes a plurality of stator teeth having a coil of wire wound thereon. A heat transfer device is further included, wherein the heat transfer device transfers heat away from the stator coils toward the bearing region. The transfer of heat may raise the temperature of the bearing fluid, thereby reducing bearing fluid viscosity. The heat transfer device may include one or more air vanes to direct air through, over, or adjacent the stator and/or thermally conductive materials or elements, and may further be incorporated into a flux shield.

    摘要： For a motor having liquid lubricated bearing surface(s), aspects include providing a column shaped Capillary Seal (CS) for storing and supply lubricating liquid to the bearing surface(s). The column shaped CS may have a cross-section substantially topologically equivalent to a circle. Aspects include disposing the column shaped CS between relatively rotational motor members or between relatively irrotational motor members. Other aspects include disposition of the column shaped CS in a spiral shape where one opening of the CS fluidicly communicates with the bearing surface and another opening vents to a gas environment. Still other aspects include disposing the column shaped CS circumferentially on surfaces of generally cylindrical shaped motor members. Such surfaces may oppose a second surface that is one of relatively rotational and relatively irrotational vis the surface. The column shaped CS may circumscribe an axis of a rotating member or may be disposed parallel to the axis of the rotating member.

    摘要： For a motor having fluid dynamic bearing(s) defined by surfaces of relatively rotatable motor members, aspects include providing a capillary reservoir between relatively irrotatable surfaces. The capillary reservoir may comprise a tapering gap that is vented to a gaseous environment through one end of the gap and is in fluidic communication with the fluid dynamic bearing(s) through another end of the gap. The gap may be axial, and the capillary reservoir may be disposed coaxially with one or more of the fluid dynamic bearing(s) about an axis of rotation. The capillary reservoir may extend from proximate a top portion of the motor to proximate a bottom portion of the motor.
