  • Spindle motor having a deep-drawn baseplate
    Patent number: 7791833
    Abstract: The invention relates to a spindle motor having a deep-drawn baseplate and an aperture to receive and secure a bearing system to rotatably support a rotor. To avoid having to machine the bearing receiving portion of the baseplate in a complex process, the invention provides for a separate bush to be disposed in the aperture in the baseplate to receive and secure the bearing system. Compared to the baseplate, this bush can be worked in a simpler and more cost-saving process.
