<p>PROBLEM TO BE SOLVED: To automatically adjust the leading current of a generator, according to load, by connecting a three-phase capacitor in parallel with three-phase winding, and self-exciting it, and further, connecting a single-phase capacitor in series between the single-phase winding and the load. SOLUTION: When a rotor 3 is driven by external force, electromotive force is induced in the single-phase winding 1 and the three-phase winding 2 of a stator by the residual magnetism of the iron core of the rotor. By this electromotive force, a leading current flows to the three-phase capacitor 4, and the generator gives rise to self exciting phenomena by the rotating magnetomotive force by this current. The single-phase winding 1 and the three-phase winding 2 of the stator are kept at terminal voltage. Here, a single-phase capacitor 5 is connected in series between the single-phase winding 1 and the single-phase load 6. Hereby, the leading current of the generator can be adjusted, according to load change.</p> |
