摘要： A rotating shaft is required to have an overhang for the mounting of a generator for an AC-exciter, the shaft length being increased correspondingly. The overhang may become the cause of generating shaft vibrations. A turbogenerator has a rotor over which a field winding is disposed, a coupling co-cut from a rotor shaft, an AC exciter for supplying a DC current to the field winding through a rectifier, and a generator for the AC-exciter, the generator including a permanent magnet as a field generator and supplying a DC current to a field winding of the AC exciter through the rectifier. The AC exciter and the generator are disposed over the rotor shaft. The rotor is rotated through engagement between a turbine and the coupling. The generator for the AC-exciter is mounted in a position on the side nearer to the turbine than a stator of the turbogenerator.
