Abstract
A winding tool for forming wire coils in a stator stack for a dynamoelectric machine including a base structure having a cylindrical wall and forming members for forming wire located in the stator stack during the winding operation. The winding tool includes wire apertures for feeding wire into the slots of a stator stack during a winding operation, and the forming members include forming blades for extending into the slots of the stator stack to push the wires positioned therein radially outwardly. In addition, end formers are provided at longitudinal ends of the forming blades for extending across the end faces of the stator stack to position the end turns of the wire coils radially outwardly. An actuator structure is provided for actuating the forming blades and end formers simultaneously at predetermined times throughout a winding operation to thereby form the wire coils radially outwardly and create greater slot fill densities.
