Abstract
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.
