ABSTRACT:
An apparatus and method for preforming and final forming the winding end turns of a stator. The apparatus includes an elongated arbor whose end includes a plurality of radially moveable blades and a cam. A pair of outer diameter jaws is positioned around the end turns whereby the arbor initially can move through the end turns to preform the end turns. After the arbor is moved into position, the end turns are final formed by reducing the volume of the end turn spaces defined by the outer diameter jaws. The coils are final formed by the movement of the end turn height rings into the end turn spaces defined by the outer diameter jaws.
