ABSTRACT:
A winding for a .DELTA.-connected, two-layer, three phase electrical machine with at least two shunt connected sets of coils per phase wherein the winding is arranged such that two adjacent sets of coils are connected with the coils of one set being cross connected and the other set being uncrossed. The coil end overhangs of the crossed set are longer than the overhangs of the uncrossed set. The voltage difference between adjacent conductor rods of one layer thus amounts, at all phase changes, at most to one winding voltage.
