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.

摘要： A high pressure boundary seal adjacent at least one of the bearings of the spindle motor. The motor itself includes a shaft, typically a fixed shaft and a rotor supported by bearings and rotating outside the shaft. The high-pressure boundary seal comprises a ring which surrounds the shaft across a small gap and is supported from and rotates with the rotor or hub. In a first embodiment, a herringbone pattern is defined on the inner surface of the ring or the outer surface of the shaft. The upper and lower sections of the herringbone pattern are substantially equal so that a zone of high pressure is established at about the center of the pattern. This high pressure boundary zone prevents the flow of any contaminants from the interior of the motor or the bearing between the shaft and the sealing ring out into the interior section of the disc drive housing where they could potentially contaminate the disc.

摘要： A fluid dynamic bearing including a sleeve and a counterplate captured within a shoulder on the sleeve and including a threaded mounting extension for mounting the assembly from a base or the like. A rotating shaft is incorporated within the sleeve; the shaft includes a thrust plate which rotates in a recess defined between the counterplate and the sleeve. To incorporate this assembly into a disc drive or the like, the threaded mounting extension only needs to be mounted within a base, with a nut screwed over the threaded mounting. The base typically includes a raised portion; the sleeve is cantilevered from this base for further stability and eliminate the possibility of vibration of the shaft and sleeve with rotation of the shaft. The end of the shaft distal from the threaded mounting supports a hub which in turn supports a backiron and magnet. The base supports a stator aligned with the magnet; energization of the stator will cause rotation of the hub and the shaft.

摘要： A disc drive includes a disc drive motor for rotating a storage disc. The motor includes a motor base which carries a wiring assembly having a plurality of electrical contacts. A rotor hub is rotatably coupled to the base and rotatably carries a storage disc. The rotor hub includes a permanent magnet. A stator assembly includes a plurality of stator windings adapted for operation with the permanent magnet of the rotor hub. A wire guide coupled to the stator assembly positions wires of the stator windings adjacent the electrical contacts of the wiring assembly. The wires are soldered to the contacts after which the wiring guide can be removed. The stator assembly can be "potted" in an adhesive to reduce problems associated with resonant frequency of the disc drive motor. The wire guide acts as a retainer for the adhesive preventing the adhesive from interfering with rotation of the rotatable hub.

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： 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.

摘要： A method for setting a gap in a hydrodynamic bearing of a disc drive spindle motors and a motor having such a bearing gap. The method comprises mounting a rotor hub having a central journal sleeve onto a shaft that has been secured to a support after having had a lower thrust bearing pressed onto the shaft in communication with said support, adding an amount of hydrodynamic fluid into the rotor hub's journal sleeve, pressing an upper thrust bearing onto the rotor shaft until contact is made with the rotor hub, and rotating the hub until axial forces balance and set the bearing gap.
