ことを特徴とする交流出力併合溶接発電機。 In an engine-driven AC output combined welding generator equipped with a stator wound with two windings, a welding winding and a single-phase AC output winding, and a convex-pole field rotor, the stator side In this case, among the group of slots in which the single-phase AC output winding is to be wound, a large number of conductors of the single-phase AC output winding are concentrated in the slot occupying the central part of the slot group. ,
The winding structure is such that the number of conductors to be inserted decreases as the distance from the slot in the center increases, and on the convex pole type field rotor side, the field winding is not wound around the rotor. In addition to providing a commutating pole, the commutating pole is a rotor having a structure in which the field winding wound around the magnetic poles on both sides becomes a magnetic pole with a polarity different from that of the magnetic poles on both sides when no load is applied. When welding current flows through the winding, the polarity of the above-mentioned complementary pole is reversed due to the armature reaction of the welding winding, improving the voltage fluctuation of the single-phase AC output winding during welding, and improving the single-phase AC output waveform. An AC output combined welding generator characterized by improving distortion of the AC output.
