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： 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： A method for setting one or more hydrodynamic bearing gaps in a disc drive spindle motor is provided. In one embodiment, a method setting one or more hydrodynamic bearing gaps in a disc drive spindle motor includes disposing a rotary member against one or more working surfaces such that substantially no gap exists therebetween and inducing creep between the rotary member and the working surfaces. The creep creates a bearing gap therebetween the rotary member and at least one of the working surfaces. The creep may be induced by thermally cycling the motor components or applying a force to a tool coupled to a member having at least one of the working surfaces disposed thereon.

摘要： The tooth saturation level is improved and electromagnetic harmonics reduced by reducing the path cross-section of area in the tooth with a geometrical means such as punched holes through the stator laminations. The punched holes alter the magnetic flux pattern by forcing the flux to go around the holes, providing a greater concentration of the flux within regions of the teeth, as well as, depending on the position of the hole along the long axis of the tooth, redistributing the flux density in the air gap. This redistributed flux density will also reduce the harmonics to improve the electromechanical device electromagnetic performance.
摘要翻译：通过减少齿中的区域的路径横截面，通过几何装置（例如通过定子叠片的穿孔），改善了齿饱和度并减小了电磁谐波。冲孔通过迫使助熔剂绕过孔而改变磁通量图形，在齿的区域内提供更大浓度的助焊剂，以及根据孔沿着牙齿长轴的位置，重新分配气隙中的通量密度。这种重新分布的磁通密度也将降低谐波，从而改善机电装置的电磁性能。

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： Part gap spacers that are disposed between parts in a fluid dynamic bearing motor or hard disk assembly are provided herein. Part gap spacers are designed to off-set adjacent parts such that part-to-part spacing has less variation in tolerance accumulation. Part gap spacers also allow for greater control of bond line thickness of adhesives, and control of gap distances for bearing fluids, and allows for electrical conductivity across bonded parts.
