<p>PROBLEM TO BE SOLVED: To provide a generator which can supply not only three-phase power but also both the three-phase power and a single phase three-line power simultaneously. SOLUTION: Three-phase armature coils 1-7 are star-connected to a neutral O1, and both a three-phase power and a single phase three-line power can be outputted by switching. Two phases among three phases have respectively two armature coils 1, 4 and 3, 7 with the identical number of turns, and the other phase has one armature coil 2 with the identical number of turns as those of the two phases and armature coils 5 and 6 with a half the number of turns of the previous one. A switching means 23, by which a mode where only the three-phase power is supplied and a mode where both the three-phase power and the single phase three-line power are supplied are switched, is provided.</p> |
