Abstract:
1. A rotating electrical machine, comprising: an induction machine which includes a stator having a stator conductor capable of producing a rotating magnetic field and a first rotor having a first rotor conductor capable of producing a rotating magnetic field, and produces an induction current in one of the stator conductor and the first rotor conductor by a rotating magnetic field generated in the other of the stator conductor and the first rotor conductor, thereby exerting a torque between the stator and the first rotor; and a synchronous machine which includes a second rotor coupled to the first rotor and having a second rotor conductor connected to the first rotor conductor and capable of generating a rotating magnetic field, and a third rotor having a magnetic pole for generating field flux and rotatable independent of the second rotor, and exerts a torque between the second rotor and the third rotor by the interaction between the rotating magnetic field generated by the second rotor conductor and the field flux generated by the magnetic pole, wherein the first rotor conductor and the second rotor conductor are connected to cause the rotating magnetic fields, generated when electric current flows through the first rotor conductor and the second rotor conductor, to be in opposite directions between the first rotor conductor and the second rotor conductor, so that a torque exerted to the first rotor and a torque exerted to the second rotor are in the same direction.
