摘要： A circular magnetizer is disclosed comprising circular insulating inset holding pans of axially disposed wires, each pair carrying a current oppositely directed from the adjacent pair, the insert being disposed within and facing a back iron across a circular gap of sufficient width to allow a circular magnet to be disposed therein and spaced by a gap from the insert and/or back iron. The pan's of wires are arranged to create flux lines which will establish alternating magnetic poles separated by null zones in the magnet.

摘要： This invention deals with compensating for thermal changes such that the spindle motor bearing preload remains as constant as possible throughout the disc drive operational temperature range. This is achieved by selecting a combination of materials with a composite thermal expansion that offsets the differential expansion of the steel bearing supports and the ceramic balls. The change in materials and configuration can be either that of the shaft, the hub, the support members, or any combination thereof.

摘要： Method and apparatus for providing a controlled resistance electrical path from one moving element of an electrical device to second or subsequent element. An electrically conductive media is introduced between the rotating and static element of an electrical device. The media, e.g. conductive grease, may be introduced into the bearings of the device. Alternatively, a housing may be disposed upon one of the elements. Into this housing is introduced a quantity of electrically conductive media and a contact element. The contact element is integral with, or is preloaded against, one end of the shaft of the second element, thereby forming an electrical path from the shaft, through the media to the housing and thence to the first element of the device. The contact element may be seen therefore to be floating in contact with the conductive media, thereby forming a controlled-resistance rotary electrical connector. Physical contact between the contact element and the housing may be implemented or not, as the particular application requires. This rotary connection methodology is especially applicable to the controlled grounding of the rotor of a disc drive electric motor with respect to the stator thereof.

摘要： A motor or bearing which incorporates the use of a capillary seal adjacent a bearing race between the shaft and surrounding hub or housing. The seal may take a plurality of forms, including a straight capillary seal; a seal formed between the housing and a seal ball having different radius of curvatures (preferably with the housing internal surface having a larger radius); or a centrifugal capillary seal comprising a male cone supported on a fixed or rotating shaft, and a female cone supported on a housing. The use of a capillary seal rather than ferrofluid seal should also provide a reduction in resistance across the seal gap compared to a ferrofluid seal.

摘要： A connector assembly comprising a base portion which plugs into the base of the motor shaft and a connector body having electrical interface rods along an axial face thereof. A flexible printed circuit having one end connected to the stator has dedicated connector pads on a surface thereof which line up with and are intended to be pressed against the molded body connector rods. To maintain the pads and rods in tight electrical contact, a connector snap spring assembly is snapped in place over the connector body. The snap spring assembly is assembled in two parts comprising a first U-shaped connector snap having a base and two arms, the arms being sized and adapted to snap over shoulders of the molded body; and a connector spring which is pressed in place over the body of the connector snap and includes a plurality of flexible fingers which are aligned with the flexible printed circuit pads and the molded body connector rods so that when the arms of the snap spring assembly are snapped over the shoulders of the body, the springlike fingers tightly press the pads and connector rods together. A hole is formed in the printed circuit axially displaced from the connector pads; a finger extending radially from the connector body passes through this hole to maintain the axial alignment of the flexible printed circuit with the remainder of the press fit connector.
