In another aspect, fluid containment structures are molded into the motor component, reducing the number of components as compared with machined metal components. In a further aspect, bearing structures such as grooves are molded into the motor component, thereby eliminating processes such as electrochemical machining.

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： 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.

摘要： A single thrust bearing fluid dynamic bearing (FDB) design, including a typical dynamic bearing design which has a ring-shaped or circular thrust plate mounted at or near the end of a shaft, wherein the shaft defines together with the surrounding sleeve a journal bearing by providing grooves on one of the two surfaces facing the gap between the shaft and sleeve. On the thrust plate, only one of the two surfaces is grooved to establish an active thrust bearing. The rotor is then biased against the single active thrust bearing with a constant force generated by a magnetic circuit.

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.
