Vertical-axis wind driven generator with double layers of wind wheels and method thereof for speeding up rotation of wind wheel

The invention discloses a vertical-axis wind driven generator with double layers of wind wheels and a method thereof for speeding up the rotation of the wind wheel. The vertical-axis wind driven generator is characterized in that: the outer surface of a stator is closely attached to the inner surface of an outer sleeve of the stator; a rotor is arranged in a central hole of the stator; the upper and lower ends of the rotor are connected with the stator through rotor bearings; the upper layer of wind wheel is fixedly connected with the outer surface of the rotor; the lower layer of wind wheel is fixedly connected with the outer surface of the outer sleeve of the stator; and vanes of the upper and lower layers of wind wheels are fixedly connected around axle centers of the wind wheels in the same direction respectively, and rotate in opposite directions. The vertical-axis wind driven generator has the advantages that: the relative rotation speed of a stator coil in a magnetic field of a rotor permanent magnet is obviously increased to greatly improve the output power of power generation because the rotation directions of the vanes of the upper and lower layers of wind wheels are opposite to each other; and due to the design of the bent curved surface of the vanes, wind from any direction can be received, the rotation directions of the wind wheels are kept constant and the utilization ratio of wind energy is high.
