Abstract
A three-phase winding for numbers of poles 2p=4 comprises 'with' and 'counter' coil groups which are arranged asymmetrically and connected in series in such a way that there is no change of the maximum voltage present at the phase transitions, where this maximum voltage is determined for numbers of pole pairs 2p=6 by the sum of the absolute values of the adjacent potentials .vertline.U.sub.1 .vertline.+.vertline.U.sub.2 .vertline.=(3p-1) U.sub.SG with a corresponding minimum value of U.sub.1,2 =(p-1) U.sub.SG where U.sub.SG is the coil group voltage. The six winding ends (U, V, and W; X, Y and Z) are arranged physically side-by-side within a pole pair, and, in general, at most only four or six wiring connections need to be installed, only at two short respective circumference zones side-by-side.
