ABSTRACT:
An improved, simplified spindle motor design for use in a disc drive is provided, which utilizes a two-piece shaft and provides a central connector in the bottom section of the shaft which can be easily connected through the base to a power source for the motor. The improved spindle motor has a stator and motor connector which can be easily assembled into the spindle motor before the bearings and other elements are installed so that the cleaning and soldering of the stator and motor connector can be efficiently achieved. Further, the spindle and motor connector design incorporates an effective electrical grounding path between the stator and the central shaft of the spindle motor.
