Abstract
In order to obtain any number of poles in the ratio p.sub.1 : p.sub.2 = 3m : 2n in a pole changeable three phase winding having nine base winding branches and only six connecting points with a simple, symmetrical, low harmonic content winding, three equiphasal induced coil sides belonging to the same phase of the winding are arranged such that for a pole pair number p.sub.2 they are located in three respective slots appearing as vectors with the same direction in the p.sub.2 pole pair slot-vector star or, in the case of at least two coils being arranged in each slot layer, two of every three such equiphasal induced coils belonging to the same phase for a pole number p.sub.2 are accommodated in a common slot with the third in a second slot appearing as a vector with the same direction in the p.sub.2 -pole pair slot-vector star.
