ABSTRACT:
A spindle motor incorporates a hollow shaft and a prewound stator having an interconnect ring attached to one end of the stator assembly. The interconnect ring is preferably a printed circuit or flexible printed circuit; it is bonded to the stator stack before the coils are wound, and the start and finish of each phase winding is terminated to the interconnect ring. Once the stator is assembled onto the shaft, connector wires can be fed up through the shaft and terminated at the interconnect ring. Traces on the interconnect ring join the wires to the proper phases and to the commons to control motor operation.
