Abstract
A two layer cord winding for a three phase electric machine in which each of the three winding circuits comprise coils with a number of turns which fill a slot layer along with other coils which have a reduced number of turns and do not fill a whole slot layer. In slots wherein the coils with a reduced number of turns are located, the remaining space is filled by a coil with reduced turns from another of the three circuits of the three phase machine.
