Abstract
A method for producing a conductor bar including transposed stranded conductors for a large, rotating electric machine. The method includes a first step of cabling a plurality of electrically insulated individual wires to form a plurality of identical stranded conductors having an essentially circular cross section. In a second step the stranded conductors are helically wound around a winding spindle in the manner of a Roebel transposition so as to form a conductor loop, wherein the winding has a profile adapted to a final cross sectional shape of the conductor bar. In a third step, the winding spindle removed from the conductor loop. In a fourth step, the conductor loop undergoes a press-forming procedure that gives it the final cross sectional shape, especially, for example, a rectangular shape.
