Abstract:
1. A method for producing a bar winding ( 18 ) for a stator ( 16 ) of an electric machine, which is a claw pole alternator for motor vehicles, which includes at least four conductor segments (I through VI; 36 ) in every winding overhang ( 45 , 46 ), which are radially superposed and are to be interconnected in pairs, wherein the stator ( 16 ) has an annular-cylindrical core ( 17 ) with a machine axis ( 27 ) and wherein the core ( 17 ) has grooves ( 34 ) open radially inward toward the machine axis, wherein said conductor segments are inserted in grooves ( 34 ) of the core ( 17 ) in a direction of the machine axis ( 27 ), comprising the following steps: forming a welded connection by connecting ends ( providing at least one electrode (±E, ±E wherein after insertion of the conductor segments, an insulation (
