Abstract: The present invention is concerned with the driving mechanism of winding needles which dispense wire to form the wire coils of a dynamo-electric machine component. Generally, such wire winding is achieved by providing translational, rotational, and radial motions to the winding needle relative to a reference structure of the component. The present invention provides wire winding solutions for causing the winding needles to accomplish predetermined motions with respect to the component so that wire is predictably positioned on the component to form the wire coils. In particular, the present invention provides a driving mechanism with coaxial hollow shafts that impart the necessary motions to the winding needle. In one aspect of the invention, the inner shaft is able to mirror the rotation of the outer shaft to provide rotational motion to the winding needle.

The same holding members that are used to hold the portions during winding may be used to hold the portions during assembly of the portions into machine components.
