An apparatus and method for performing and final forming the winding end turns of a stator. The apparatus includes an elongated arbor on the end of which 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 an end turn heights ring into the end turn spaces defined by the outer diameter jaws.

Method and apparatus for preforming and final forming of stator coil end

An apparatus for inserting coils and wedges into a dynamoelectric machine stator core.The apparatus includes a housing and an array of circumferentially spaced elongated wedge guides mounted on the housing for guiding wedges during insertion thereof into a stator core. Ends of the wedge guides are disposed adjacent the stator core. A plurality of elongated blades cooperate with the wedge guide array for axial movement relative to the wedge guides. A stripper is operatively mounted within the plurality of blades for axial movement relative to the blades. A wedge support is associated with the stripper and the wedge guides for supporting wedges at points intermediate the stripper and the ends of the wedge guides. The wedge support is a disk with a cylindrical outer surface from which a plurality of fins extend radially outwardly for contacting the wedges at intermediate points between the stripper and the ends of the wedge guides.

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.
