Abstract:
A coil winding (20) that consists of a number of wires (22) braided with one another and bent multiple times in opposite directions such that mutually parallel legs (28, 30) of the wires (22) which are intended to fill the slots (16) are connected by winding overhangs (32, 34) which project from the end face of the stators (10) or rotors. The winding overhangs (32, 34) each have two oblique winding overhang sections (36, 38, 40, 42) having a winding overhang tip (44, 46) in between. The wires (22) are arranged one behind the other in a longitudinal direction (L) of the coil winding (20). The winding overhangs (32, 34), which are distributed in the longitudinal direction (L) over the entire length of the coil winding, of at least one wire (22) protrude transversely to the longitudinal direction (L) beyond the winding overhang (28, 30).
