VERTICAL-AXIAL WIND UNIT Russian patent published in 2015 - IPC F03D3/00 F03D3/06 

FIELD: power industry.

SUBSTANCE: vertical-axial wind unit contains a hub rigidly secured in space, located in centre of rotation, where electric generator and rotor are arranged. The rotor contains a cylindrical shaft, from it radially in horizontal plane the power cross-arms exit, they are closed in aerodynamic fairings, at their ends there are vertical blades. The cylindrical shaft with possibility of rotation passes through the guide sleeve rigidly secured at end of the vertical mast. The electric generator contains casing, in its plane the laminated core secured to hub is installed, it has slots in which the winding coils are located. In stator cylindrical cavity the electric generator rotor is located with possibility of rotation. The rotor contains inductor made with possibility of Halbach magnetic circuit creation or with possibility of radial or tangential magnetizing. The electric generator casing is equipped with the first and second shields made with possibility of rigid engagement with the appropriate end edges of the electric generator casing.

EFFECT: invention use results in increased service life and operation reliability of the wind unit and its electric generator due to significant friction decreasing in bearings, increased generator efficiency, reduced weight of the rotating parts, increased rotational speed of the electric generator inductor.
