Abstract: An annular tool for insertion of stator coils to a stator includes a plurality of circumferentially spaced pivotally mounted cuff support fingers to facilitate separation of the tool from the stator after the coils have been inserted. The tool is in the form of an annular base member having a central opening that receives a conventional insertion tool. An annular shoulder formed in the base member supports a stator about its periphery during the coil insertion process. The cuff support fingers are biased into a position of repose where they extend radially inwardly into the central opening. When the coil insertion process is completed, the fingers pivot upwardly to allow the tool to slide downwardly with respect to the insertion tool so that the tool is separated from the stator and coils. The completed stator and coils and the tool are then removed from the insertion tool.

Abstract: Wedge feeding means for a short stroke dynamoelectric machine coil and wedge inserting apparatus of the type in which the slot wedges for an internally slotted dynamoelectric machine stator core member are inserted into the stator in a two stroke movement. The wedge feeding mechanism includes front and rear wedge pushing elements which are moved by a hydraulic ram. With each forward thrust of the hydraulic ram, the front pushing element inserts a group of wedges into the stator core member and the rear pushing element advances a second group of wedges to an intermediate position. As the hydraulic ram is retracted, the front wedge pushing element cams along the underside of the wedges located at the intermediate position in returning to its initial position. With the next stroke of the hydraulic ram, the front pusher element engages the wedges at the intermediate position and the rear pusher element engages a new group of wedges to move both groups respectively to the stator and the intermediate position.
