Abstract: The invention refers to a wind generator of electrical current production with a vertical axle and inhibition over-speed laps. the wind generator is setted on a steady duct on the upper place of which there is a thrust bearing. There are three (internal) laps mounted on the generator and under the thrust bearing. These flaps are totally the same. They are setted in 120 degrees corner among them. Three other laps (external) are fixed on these flaps. The external flaps are constructed with aerodynamic cross section. These laps have special ribs and housings for edge support while a wire rope mounted to the internal of the laps prevents the spreading in case of fracture. According to the invention we have internal and external flaps. Because of the rotation speed increasement the external flaps gradually change place so the incidence angle of the wind changes and the flaps resist to the wind flow keeping the rotation speed steady.
