    • A fluid dynamic bearing motor and method are described, wherein motor components, including complex shaped motor components, are molded of plastic. The molding ensures form control and dimensional control thereby accomplishing design requirements, and eliminating or reducing component costs and component machining. The mold can be shaped to form various motor geometries, thereby eliminating the need for multiple component assembly and related assembly costs. In an aspect, a plastic integral motor hub is formed by injection molding. Alternatively, a plastic motor hub is affixed to a metal sleeve. 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. In yet a further aspect, a plastic hub faces a thrustplate, reducing expensive sleeve machining.

    • A different-diameter clearance of high accuracy is created at low cost, thereby improving the bearing performance and the sealing capability. An inner periphery 5a of a molded part 5 having a step from an inner periphery 4a of an electroformed part 4 is molded to a nonconductive coating 9 which covers the surface of a master 8. When the nonconductive coating 9 is removed, a radial clearance 7 having a diameter greater than that of a bearing clearance 6 is created between the inner periphery 5a of the molded part 5, which is exposed to the interior, and an outer periphery 2a of a shaft member 2. A bearing member 3 which forms this bearing clearance 6 and the radial clearance 7 with the shaft member 2 is manufactured by: performing electroforming on the master 8 with the nonconductive coating 9 formed on part of the surface of the master 8, thereby forming the electroformed part 4; then injection molding the bearing member 3 with the electroformed part 4 and the nonconductive coating 9 on the surface of the master 8 inserted into a cavity 15; and then removing the nonconductive coating 9 from the bearing member 3.
