    摘要： A base of a data storage system includes a motor assembly. The motor assembly s includes a rotor that extends through an aperture in the base. The aperture extends from an inner surface to an outer surface of the base. The motor assembly also includes a motor stator mounted on the outer surface of the base. The motor stator includes a plurality of stator teeth radially and symmetrically arranged about the aperture in the base which are configured to support stator wires.

    摘要： Stator and base plate interface alignment is provided for a spindle motor, meeting design specifications such that motor performance is maintained. A portion of a surface of the stator is separated from the base plate. Accurate stator z-height, parallelism and concentricity are provided for use with a low profile disc drive memory system. In an aspect, laminations are formed about a stator and the bottom layer laminations are formed with a smaller diameter than the top layer lamination. The stator bottom layer laminations seat on a flat base plate machined surface, avoiding a base plate corner radius. Precise machining of a small corner interface of the base plate where a stator is typically seated and aligned with the base plate is made unnecessary. Component machining costs, wear and tear to machining systems, and machining process cycle times are reduced.

    摘要： A base plate of a disc storage system including an interior and an exterior surface, an entrance hole passes between the two surfaces and a groove surrounds the entrance hole and reduces the passage of air along an interface between the exterior and the interior surfaces. The groove may be in the shape of a circle or other alternative shapes such as a rectangle, as considered within the plane of the interior surface. An overmold is molded to the base plate and fills the groove. The plate is generally made of a plastic. The groove is amenable to the stamping process as well.

    摘要： A base plate for a spindle motor is provided defining a minimal axial gap with a relatively rotatable magnet. In an example, a surface of the base plate is positioned at 0.1 mm from an adjacent surface of a relatively rotatable magnet. The base plate is comprised of a composite material such that stiffness is improved and acoustic vibration is reduced, while maintaining low power consumption and a fast start-up time. A first material, being a nonmagnetic material is employed adjacent to a motor magnet, and a second material having a preferred stiffness is employed at a greater radial distance from the magnet than the radial distance between a stator and the magnet.

    摘要： An apparatus and associated method for making a base for a data storage device. The base has a plurality of raised pads defining coplanar supporting surfaces. The surfaces are adapted for supportingly engaging intermittent portions of a component supported by the base so that the base clearingly disengages other portions of the component between the pads.

    摘要： The invention includes techniques for mounting a printed circuit board (PCB) on a housing for an electronic device. The housing includes a top cover that combines with a base to form an internal space within the housing. The PCB has at least one tab that extends from it and fits within a recess formed by the base to secure the PCB on a side of the base opposite to the internal space. The electronic device may additionally include a shield such that the PCB fits between the shield and the base and the shield assists in securing the PCB to the base. The housing may also include a locking mechanism to constrain the PCB tab to the base. Embodiments of the invention allow for a PCB to be mounted to an electronic device housing without the use of screws.
