Vertical wind turbine comprising rotor blade-supporting pitch motor, as well as kit for same, and method for operating same

Abstract

The present invention relates to a vertical wind turbine ( 1 ) with a plurality of vertical blades ( 7 ), which are each supported such that they are motor-driven pivotable around a respective blade rotation axis (C 7 ) independently of one another, and are rotatable on a common circular path (K) around a vertical rotor rotation axis (C 2 ), and to a method for operating the vertical wind turbine ( 1 ), wherein angular positions of vertical blades ( 7 ) of the vertical wind turbine ( 1 ), which are each supported such that they are rotatable around a respective vertical rotor rotation axis (C 2 ) and are motor-driven pivotable around a respective blade rotation axis (C 7 ) independently of one another, are being predetermined. According to the invention, the vertical wind turbine ( 1 ) is operated in a particularly efficient and material-protecting way in that the angular positions of the blades ( 7 ) are each predetermined by means of at least one pitch motor ( 27 ) at least partially supporting the respective blade ( 7 ).
