Title
(EN) WIND POWER GENERATOR
(FR) GENERATEUR D'ENERGIE EOLIENNE
Abstract
(EN)
A wind turbine. Front and rear rotors are provided to rotate in opposite directions. First and second shafts arranged in a rotator are constructed to rotate in opposite directions and are rotatably connected to a coil and a magnetic element of a generator. A stator having a contact terminal to be brought into sliding contact with an output terminal is formed adjacent to the rear end of the generator. Since the coil and magnetic element of the generator are rotated in opposite directions, power generation efficiency is significantly improved. Because the construction of the wind turbine is simplified, productivity is improved, a fabrication cost is reduced, and operation noise is decreased. Due to the fact that susceptibility to a change in wind direction is remarkably improved, high power generation efficiency can be kept even at a place where a wind direction frequently changes.

L'invention concerne une éolienne comprenant: des rotors avant et arrière disposés de sorte à pivoter dans des directions opposées; des premier et deuxième arbres disposés dans un rotateur, conçus pour pivoter dans des directions opposées et reliés rotatifs à une bobine et à un élément magnétique d'un générateur; un stator pourvu d'une borne de contact à mettre en contact coulissant avec une borne de sortie, formé adjacent à l'extrémité arrière du générateur. Comme la bobine et l'élément magnétique du générateur pivotent dans des directions opposées, l'efficacité de production d'énergie est considérablement améliorée. La simplification de la structure de l'éolienne permet d'obtenir une productivité améliorée, un coût de fabrication réduit et un bruit de fonctionnement diminué. Comme la sensibilité aux changements de direction du vent est remarquablement réduite, une efficacité de production d'énergie élevée peut être maintenue même dans un endroit où la direction du vent change fréquemment.
