Helix-like winding with increased field advantage

It is specified with a magnetic pole number p, a stator (3) for an electric alternating current machine (1), wherein the stator (3) having a central axis A, wherein the stator (3) has a stator winding (4) having a plurality of turns of conductor (13j) which each have at least in a partial section (L) (A) extend with respect to the central axis helically wherein the individual conductor turns (13y) to a total of n electrical strands (u1, u2, w4 to w3) are grouped, characterized in that the number n of the strands is greater than three, in particular an integer multiple of three. Furthermore, an electrical machine (1) having such a stator (3) is specified.
