A power generator is provided which, when used at an electric power generating facility such as a wind power plant, etc., would not be bulky and would not impede wind capture by a wind turbine; instead, it can raise the generated voltage without impeding wind capture. The invention provides a permanent magnet generator comprising a generator shaft; at least three rotors, which are secured with the generator shaft, constituted by a plurality of a plate-shaped structure having a permanent magnet attached thereto, and each disposed in the longitudinal direction of said generator shaft; and a stator, which is plate-shaped structures with a stator coil of a wound copper wire disposed in at least two gaps formed by said rotors, evenly-spaced apart from said generator shaft. The rotors and stators are disposed alternately in the longitudinal direction of said 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. |
