  "textContent": "A turbogenerator comprises a rotor over which a field winding (21) is disposed; a permanent magnet (13) disposed on said rotor; a generator for alternating-current excitation generating a current with a magnetic field produced by said permanent magnet (13) ; an exciter (4) for supplying a current to the field winding (21) of said rotor based on the current generated by said generator for alternating-current excitation; and a turbine for producing motive power to rotate said rotor. The permanent magnet (13) of said generator for alternating-current excitation is disposed between a pole shoe (12) and a rotating shaft (1) of said rotor. ( Fig. 8 )",
