<p>This present invention relates to a wind rotor with a vertical shaft, formed by means of a vertical shaft (1), two horizontal end supports (3, 3') and a plurality of blades (4, 4') arranged between said supports. The features of the invention are centered on the fact that the blades (4, 4') are of two types, in an alternating arrangement, blades (4) prepared and configured for forming drag elements and blades (4') prepared for forming lift elements, with the additional particularity that the latter stall when they exceed a pre-established wind speed, causing a braking effect in the rotor. This structure eliminates many of the drawbacks of the known wind rotors with a vertical shaft, such that it does not require an important starting torque, a braking system with strong winds, or the orientation and reorientation with respect to the dominant winds. Nor is it limited to being used with laminar winds, and it does not require being arranged at great heights, being able to be installed on a short support post (2) in optimal operating conditions.</p> |
