    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 laminations. 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 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.

A first gasket retention groove is formed in one of the plurality of parallel surfaces that is proximate a top cover. A second gasket retention groove is formed in one of the plurality of parallel surfaces and at least partially surrounds a motor mounting aperture. A third gasket retention groove is formed in one of the plurality of parallel surfaces and at least partially surrounds a connector mounting aperture. A first cured-in-place elastomer is formed on the base plate and is confined by the first gasket retention groove. A second cured-in-place elastomer is formed on the base plate and is confined by the second gasket retention groove. A third cured-in-place elastomer is formed on the base plate and is confined by the third gasket retention groove.

    摘要: A base deck is formed by a method of forming the base deck for use in a data storage device. The data storage device includes a motor assembly rotating a disc into a data exchange relationship with a read/write head, in which the motor assembly is supported by the base deck formed by steps for forming the base deck. The base deck includes a base plate upon which a formed-in-place top cover gasket, a formed-in-place motor mount gasket, a formed-in-place connector gasket, a formed-in-place bottom pole damper and a plurality of formed-in-place impact dissipation members are secured to the base plate after the base plate undergoes an application and curing of formed-in-place gasket material. Upon assembly of the data storage device, the cured formed-in-place gaskets provide seals, which preclude contaminants external to the data storage device from migrating into an internal environment of the data storage device.

    摘要: A fluid dynamic bearing motor and method are provided for use with various disc drive memory device products differently rated by operational rotational speed. The operational speeds are those speeds measured during reading and writing memory operations to the memory device. In an aspect, the present invention meets full operating requirements, including stiffness and power requirements, at multiple rated speeds for use with either standard or high-end performance disc drive products. Costs associated with a dedicated manufacturing line for high-end products are substantially reduced. A single manufacturing line can serve both standard and high-end disc drive memory device products. The present invention is especially useful in reducing costs of 2.5 inch notebook products that are typically marketed in two levels of performance, namely, 5400 RPM standard performance products and 7200 RPM high performance products.

    摘要: An apparatus and method for balancing a disc stack assembly of a disc drive where a clamp is used as a counter-balance as well as for securing a disc to the disc stack assembly. The clamp and spindle motor are configured for positive engagement and alignment with the use of a minimal number of parts. The clamp includes a cavity through which a protrusion or a shaft of the spindle motor hub may extend. The clamp may be further secured in a desired orientation by the use of a single fastener.
