Abstract
A conductor bar for a large, rotating electric machine includes a press-formed conductor loop having a rectangular cross-sectional shape. The conductor loop includes a plurality of identical, helically wound, Roebel transposed, stranded conductors. Each of the stranded conductors includes a cable including a plurality of electrically insulated individual wires, wherein the cross-sectional shape is constant along a length of the conductor bar.
