Disclosed in a wind rotor ( 1 ) comprising one or more blades ( 3 ) rotating around a vertical, central axis ( 4 ) within a main bearing ( 5 ), said blades being parallel to said vertical axis ( 4 ), said blades being connected via crossbars ( 6 ), said blades being disposed freely rotatably in bearings ( 7 ), and said blades being orientable by means of a wind vane ( 9 ). Said blades ( 3 ) comprise a symmetrical aerodynamic profile ( 8 ) over their entire cross-section. Said rotor comprises a primary control mechanism ( 11 ), which is controlled by said wind vane ( 9 ) and aligns said profiles ( 8 ) of said blade(s) ( 3 ) along the wind direction ( 10 ) at each point of their trajectory ( 13 ) around the central vertical axis ( 4 ), said blades being disposed on said crossbars ( 6 ), and a secondary control mechanism ( 12 ), which aligns the longitudinal axes of said profiles ( 8 ) of said blade(s) ( 3 ) to the wind ( 10 ) at each point of their trajectory ( 13 ) around the central vertical axis ( 4 ) so as to produce an optimum aerodynamic force depending on the rotation angle of the crossbars ( 6 ) with respect to the wind vane ( 9 ) and the rotation velocity of the crossbars ( 6 ).
