The present invention comprises a mechanism for controlling a wind mechanism best known as aerogenerator. Said mechanism protects the aerogenerator systems when it is subjected to a wind speed higher than the design speed. The control is performed by increasing the attack angle by means of the individual rotation of the rotor blades, thus causing the detachment of the wind flow over the blades, which is also known as Stall. This mechanism is simple, since the pitch angle is modified according to the pitch moment of the blade, the maximum rotation to the Stall is controlled so as to generate induced vibrations.
