PROBLEM TO BE SOLVED: To eliminate the own gravity resistance of the generating magnet structure of a generator or the own gravity of a wind driven part such as propeller, rotor shaft or the like in a wind generator to utilize natural energy such wind force or hydraulic power to the full. SOLUTION: In a wind generating device of the type of supporting a rotor 12 having a horizontal propeller 13 by a shaft 1, for example, upper and lower magnet repellent substrates 3, 6 with bearings in the lower parts are fixed on a housing tower 2 in opposition to an upper magnet repellent board 4 and a lower shaft retaining magnetic force repellent disc 7 so that the magnetic poles are mutually coincident to provide a magnetic repellent levitation force, and a generating magnet 9 is installed to the middle of the shaft 1 to constitute a generator 8 with a coil stationarily installed to a generating housing 4 in the middle part of the housing tower 2. A magnet integrated stopper bearing 22 is provided on the bottom end part of the shaft 1 to utilize the magnetic levitation force by the different pole magnetic force on the opposed surface of the lower magnet repelling substrate 6. |
