ABSTRACT:
A method and apparatus for shaping the winding end turns of a stator assembly wherein the outside diameter of the end turns is first engaged by a set of alternate segments in a circular array and is thereafter engaged by a set of intervening segments of the array while the first set remains engaged. The motion and configuration of the segments avoids the risk of pinching a wire of the winding by eliminating relative circumferential closing movement between adjacent segments. The inside diameter of the end turns is shaped by an expandable mandrel assembly that includes interengaged shoes that have a sliding movement in expansion and contraction that also avoids the risk of pinching strands of the winding.
