Abstract: A vertical-axis wind rotor configured by concave-convex type airfoil profiles in the form of vertical helical protrusions, tilted towards counter-rotation and twisted around, the chord decreasing, where both ends are finished in the form of sharklets rotated towards the upper surface so as to eliminate the vortex, and distributed in a circular pattern around the rotation shaft thereof. The angular arrangement of the chord of the section of the profile with a spoke with respect to the shaft of the rotor is particular for making the profile work under lift conditions before reaching the normal under drag forces and complementing them, eliminating jerking, with the direction of rotation being indicated by the Coriolis effect and determining the radial distribution, the radius, the chord, the profile, and the number of them, which confers to the rotor the maximum terminal velocity at which it slows down, being maintained by the Magnus effect.
