PERMANENT MAGNET GENERATOR AND WIND POWER GENERATOR USING THE SAME

摘要

A permanent magnet generator is provided that is not bulky and does not impede wind capture by a wind turbine. The permanent magnet generator includes a generator shaft; at least three rotors secured with the generator shaft, each rotor including a plate-shaped structure having a permanent magnet attached thereto, each plate-shaped structure being disposed in the longitudinal direction of the generator shaft; and a stator, including a plate-shaped structure with a stator coil of a wound copper wire disposed in at least two gaps formed by the rotors and evenly-spaced apart from the generator shaft. The rotors and stators are disposed alternately in the longitudinal direction of the generator shaft, with a total of not less than five stages. Furthermore, a wind power generator obtained by installing a propeller on the shaft of this permanent magnet generator is provided.
