摘要： In an engine welder of the type including an output alternator having a rotor driven about a central axis with an outwardly facing, cylindrical surface and a stator with a cylindrical surface generally matching said cylindrical surface of the rotor and containing in a number of inwardly opening, circumferentially spaced, axially extending winding slots, wherein the slots include a first group adapted to receive welding current windings and a second group adapted to receive auxiliary power circuit windings. The improvement in this construction involves modifying the first group of slots to include structural means for causing a substantial increase in the flux leakage in the first group of slots, as compared to the flux leakage between the second group of slots. In this manner, the welding output of the engine welder has a substantial internal reactance and the auxiliary power circuit has a reduced internal reactance, all in the same stator. This reduces the necessity for an external reactor in the welding circuit driven by the engine welder and improves the voltage regulation of the auxiliary power circuit.
