In performing electrode coil winding, the generator stator winding may be divided into a plurality of identical or different winding units by a combination of different numbers of electrodes. For example, it may be divided into different winding units, i.e. the motor stator winding structure of the variable frequency generator set is formed with a first winding structure 110, 120, 130 and a second winding structure 140, but the number of electrodes constituting the first winding structure 110, 120, 130 is not the same as the number of electrodes constituting the second winding structure 140.
