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 invention relates to a method for producing a bar winding (18) for the stator (16) of an electric machine, especially of a claw pole generator for motor vehicles. Said stator has at least four conducting segments (36) in every coil head (45, 46) which are radially superposed and interconnected in pairs. In this manner, a resistance welding method can be used, the welding current (I) being guided through the ends (42) of the conductor pairs in a partially radial and in a partially axial manner in relation to the rotor axis (27) in the fusion zones (40).
