Abstract

The invention relates to a method for producing a stator winding (18) of an electric machine (10), in particular of an alternator, the stator winding (18) comprising at least n phase windings (120, 121, 122, 123, 124) and a phase winding (120, 121, 122, 123, 124) having several directly consecutively wound coils (82) having coil sides (88) and coil side connectors (91), the coils (82) being divided into first coils (82.1) and second coils (82.2), by means of a forming tool (100), in which grooves (105, 106; 105′, 106′) suitable for accommodating the coils (82) are provided, a first coil (82.1) being arranged in one groove (105; 105′) and a second coil (82.2) being arranged in another groove (105; 105′), characterized in that n−1 grooves (105, 106; 105′, 106′) are arranged between the first coil (82.1) and the second coil (82.2).
