Abstract: Embodiments of the present disclosure may include producing a stator of a dynamo-electric machine. The method may include moving along a predetermined rectilinear trajectory a train of pole members arranged according to a predetermined starting spatial orientation. At a predetermined passage position, a first pole member and one or more intermediate pole members may pass from the rectilinear trajectory to a circular trajectory having a centre. In some embodiments, the method may include positioning a last pole member of the train along the circular trajectory adjacent to the first pole member and to the last intermediate pole member changing, at a change position its spatial orientation from the predetermined starting spatial orientation to a final spatial orientation in which it is radially oriented with respect to the centre of the circular trajectory.

Abstract: The present invention discloses methods and apparatus for winding wire onto the slots on armature lamination stacks. More specifically, the present invention is directed to methods and apparatus for increasing time the winding components are operating on an armature winding system. The invention includes a loading/unloading unit and a holding unit that may be operated independently under most circumstances. The independent operation enables the winders of the present invention to operate at increased duty cycles, thereby increasing throughput. Additionally, the apparatus of the present invention increases the likelihood that armatures remain properly indexed during the loading transfer process to further increase system efficiency.

Abstract: Sensor arrangements are provided to detect whether initial and final wire leads were properly terminated to tang terminals of dynamo-electric machine components. The sensor arrangements may detect whether excess wire from the termination of the initial wire lead is present on a first side of a wire gripper. The sensor arrangements may detect whether excess wire from the termination of the final wire lead is present on a second side of a wire gripper. The sensor arrangements can include two sensors or a single sensor to detect the presence of the excess wire. Beam sensors, vision sensors, or tactile sensors may be used to detect the presence of the excess wire. A plunger device is provided to facilitate the tearing of thin initial and final wire leads to a tang terminal of a commutator.

Abstract: A method of winding a core having slots of different angular distances from one another and/or different shapes is provided. The method includes using a flyer winder to wind turns of wire into a first portion of the slots having a uniform distance from one another, and then using a different flyer winder to wind turns of wire into a second portion of the slots having a uniform distance from another. In addition, back-up members may be used to evenly distribute the wire in the slots during winding. Specifically, concerning slots that have walls that diverge as they approach the center of the core, back-up members that also diverge as the slots are wound are provided.
