摘要： In a method for manufacturing a bar winding for the stator of an electric machine, in particular of a claw pole alternator for motor vehicles, resistance welding is used to form mechanically and electrically reliable and permanent connections in the winding overhang of the stator even with winding configurations that include four or more superposed conductor segments, and even with the very small amount of working space that remains for the necessary connections, using a minimum of production-related outlay. With a design, in particular, of four radially superposed conductor segments in the winding overhang, particularly advantageous configurations result in terms of the placement of the bar ends and in terms of the design of the welding electrodes.

摘要： The method for making a stator includes making individual strip-shaped laminas (15) for it; stacking the laminas (15) to form a stator core (13) with grooves (18) on one side extending through the core; producing a subassembly by inserting a stator winding (17) into the grooves (18); bending the subassembly to form a cylindrical cavity so that the grooves (18) end in the cavity and connecting two ends (23) of the stator core (13) to each other by a welding seam (20) to maintain this configuration. To produce a welding seam of sufficient strength which does not exert excessive influence on magnetic properties, the welding seam depth (TS) is given by TS=0.5 mm*(Hyoke/mm−1)±ΔTS, wherein Hyoke is yoke height and ΔTS is a tolerance value. An electric machine including the stator made by this method is also described.
