ABSTRACT:
An apparatus is provided for forming field coils on a stator stack including a plurality of slots defined by stator teeth. The apparatus includes a stator nest for holding a stator stack and a winding tool extending through the stator nest for locating wire in the stator stack. The winding tool includes a wire feed aperture for feeding wire into slots of the stator stack. A drifting tool is supported on the winding tool and includes radially extending drift blades for extending into the slots of the stator stack for forming or shaping wire coils that are wound on the stator teeth by the winding tool. Longitudinal movement of the winding tool causes the drifting tool to move into and out of engagement with the stator stack.
