Abstract

A spindle motor assembly adapted for rotationally supporting a load about a base includes a rotor rotatably mounted on the base with its outer periphery capable of supporting a load, a stator and a plurality of magnets mounted on the outer periphery of the rotor. The stator includes a plurality of stator laminations with selective portions of the stator laminations forming stator cores. A plurality of magnets are mounted on the outer periphery of the rotor in an operating relationship with the stator cores. A plurality of conductors are wound on the stator cores. The stator includes a resilient covering located around the plurality of laminations and further having a routing means to route the conductors between the stator cores, an attaching means to attach the stator to the base and a connecting means. The connecting means includes a first connector block with a plurality of first conductor pads, with a first end and a second end. Ends of the conductors are connected to the first end of the conductor pads. A second connector block is mounted on the base, with the second connector block having a plurality of second conductor pads. The second end of the first conductor pads are connected to the second conductor pads of the second connector block.

Claims
