ABSTRACT:
The present invention concerns forming wire coils by simultaneously winding a plurality of wires onto a dynamo-electric machine component. In order to maximize the amount of wire that can be placed in the spacings of the dynamo-electric machine component, the turns of the wire coil must be regularly disposed without twisting the plurality of wires onto each other. Current winding apparatus may allow certain portions of the wire turns to unevenly accumulate and locally bulge outward from the collection of wire coils. Such bulges, especially in consideration of the limited spacings available on an dynamo-electric machine component, may interfere with or access to the spacings by a wire dispensing member during the winding process. The present invention proposes to perform multiple-wire winding processes that avoid wire twisting and improper disposition of the wires. Further, the present invention proposes to improve the ability of the wire dispensing member to traverse the spacings on the component. As a consequence, the winding processes performed with the present invention are less likely to be hindered by interference and are capable of obtaining more wire fill within the component spacings and higher winding speeds.
