Wind wheel has a zone arc of the stator 1, the side members of the magnetic circuit 2, sailing plumage 3, U-shaped bracket 4, the rim 5, the Itza 6, the hub 7. The u-shaped element includes a vertical side 8, a horizontal shelf 9, the mounting rails are made with nuts 10, U-shaped brackets have holes for fastening to the rim 11 and the mounting holes of the side members 12 and openings 13 for contact with the outer edges of the rim. Fastening a U-shaped element to the rim is carried out by means of bolts 14, and between the side members 2 spanned sailing plumage 3 made in the form of a cylindrical surface.

Wheel works as follows. At clash of the wind flow is the rotation of the wind turbine due to the deviation of the flow caused by the inclined position of the blades. While periodically opens and closes the magnetic circuit: the stator - side member is U-shaped element of the second spar is the stator. As a result, in the stator element of the induced EMF, which is then passed to the consumer.

Technical and economic advantage of the claimed device is the ability to use the spar of the blade at the same time as structural elements and magnetic segment generator that reduces capital costs, and also allows the use of having the smallest value on the date of sailing of feathers.
