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.

A winding for a multi-phase alternating current machine having a plurality of poles, comprising:
- a plurality of parallel winding groups (U1, V1, W1;
- U2, V2, W2;
- U3, V3, W3), each configured to be supplied by separate power sources, wherein locations of the winding groups are cyclically shifted from one pole to another, and wherein a number of the parallel winding groups (U1, V1, W1;
- U2, V2, W2;
- U3, V3, W3) is higher than two, and is selected such that a number of poles of the alternating current machine will be an even number that is a multiple of the number of parallel winding groups.
