Abstract

Method for producing a stator winding (18) of an electric machine (10), in particular an AC generator, wherein the stator winding (18) has at least n phase windings (120, 121, 122, 123, 124), and one phase winding (120, 121, 122, 123, 124) has a plurality of directly successive wound coils (82) with coil sides (88) and coil side connectors (91), wherein the coils (82) are divided into first coils (82.1) and second coils (82.2), with a forming tool (100), in which slots (105, 106; 105′, 106′) are provided which are suitable for accommodating the coils (82), wherein a first coil (82.1) is arranged in a slot (105; 105′), and a second coil (82.2) is arranged in another slot (105; 105′), characterized in that n−1 slots (105, 106; 105′, 106′) are arranged between the first coil (82.1) and the second coil (82.2).
