PROBLEM TO BE SOLVED: To improve energy efficiency by taking out torque and much energy from the shaft of a wind power rotor. SOLUTION: The angle of attack of a blade suitable for a wind speed is set, thereby taking out much energy. A rotating shaft 5 is perpendicularly provided, and a bearing 1 rotatably retaining a horizontal rotating shaft is provided with a generator 2 and a rotating shaft 3. Also in this wind power rotor, a plurality of rows of rotating blades 6, 7, 8 having different angle of attack are provided around the rotating shaft 3. Thereby, the blade suitable for the wind speed is rotated by receiving the highest energy. COPYRIGHT: (C)2011,JPO&INPIT |
