Abstract: A stator winding is disclosed for a multiple-phase alternating current machine with several parallel winding groups (U1, V1, W1; U2, V2, W2; U3, V3, W3), each of which can be supplied with separate power sources. Locations of the winding groups can be cyclically shifted when moving from one pole to another. The number of parallel winding groups (U1, V1, W1; U2, V2 ,W2 ;U3 ,V3 , W3) can be higher than two, and the number of poles of the alternating current machine can be an even figure that is a multiple of the number of winding groups.
