WIND POWER GENERATOR

Wind power generator (WPG) comprising a stator, rotor with a shaft connectable to wind turbine and a stationary superconducting coil for magnetizing the wind power generator rotor, the WPG stator comprising a multi-phase winding for producing electricity. The WPG is a synchronous generator, and the superconducting coil comprises end portions arranged to be magnetized with opposing polarities by a superconducting coil, the rotor comprises poles extending in the surface of the rotor in the direction of the shaft of the generator, the poles arranged to be magnetized using the superconducting coil, each rotor pole extends inwardly at one end of the pole such that the inwardly extended end is arranged in the vicinity of an end portion of the superconducting coil for magnetizing the rotor pole and the rotor poles comprises pole shoes formed to provide sinusoidally varying air gap flux in the air gap between stator and rotor.
