An alternating current generator of the invention has three armature windings, which are wound from a winding start end connected to a neutral point to winding finish ends, and a stator that is connected to the neutral point in Y-connection at a phase difference of 120 degrees, respectively, and configures a three-phase power source, wherein the generator comprises two taps provided at predetermined positions from the winding start end to the winding finish ends of two armature windings out of the three armature windings, and wherein one terminals of the two armature windings are connected to relevant ones of the two taps and the other terminals of the two armature windings are made single-phase output terminals.

Alternating current generator

A series-exciting device for a synchronous generator characterized in that armature windings at the side of the armature are wound using concentrated full-pitch winding or a winding method similar to the concentrated full-pitch winding; an exciting winding which is magnetically coupled to magnetic poles in a quantity odd times greater than the quantity of the poles of the said armature windings, and a rectifier which converts the electromotive force of the exciting winding into a DC are provided at the side of the field system; and a DC output terminal of the rectifier is connected to a field winding having poles in the same quantity as the quantity of the poles of the said armature windings.
