Known microelectroporation [RF Patent №2211951 / A. M. Litvinenko - Microelectrochemistry installation, publ. BI No. 25 dated 10.09.2003, application No. 20011359 46/06 from 27.12.2001, IPC F03D 9/00], in which the rotor part microelectroporation installation, includes a permanent magnet mounted in the middle of the C-shaped brackets with the help of a band of non-magnetic wire. Also known segmental rotor patent (RU 2270360 C1, F03D 9/00, 20.02.2006), which contains as the base rim.

The disadvantage of these rotors is that they cannot be used with induction generator and the complexity of attachment associated with the use of a non-magnetic binder, increased weight.

Known analogues closest to the claimed combination of essential features for a rotor of a wind power [RF Patent №2270363 / A. M. Litvinenko - Rotor wind power, publ. BI 5 from 20.02.2006, application No. 20041286 76/06 from 27.09.2004, IPC F03D 9/00].

The technical result from the use of this rotor is to reduce the weight and size of the rotor segment ferroelectromagnetic while minimizing its cost by simplifying the manufacturing technology and is ensured by the fact that magnetor the water rotor ferroelectromagnetic made in the form of ferromagnetic bodies, which are interconnected by means of bolts and non-magnetic U-shaped brackets and installed on the curved elements. Thus, the rotor includes a hub, blades, spokes, rim and the ferromagnetic body.

The disadvantage of this rotor is that its structure is difficult to use widespread tubular elements as circular and square cross-sections.

The invention is directed to reducing the weight and size of the rotor ferroelectromagnetic while minimizing its cost by simplifying the manufacturing technology.

This is achieved in that the rotor segment ferroelectromagnetic containing the hub, the blades, the rim and the ferromagnetic body and non-magnetic elements connected to one another and mounted on the rim according to the invention the ferromagnetic body is made in the form of segments of pipe, inside of which is installed fasteners, made of non-magnetic elements, in the form of segments of bars with holes for fastening bolts.

The invention is illustrated by drawings, where Fig.1 shows a General view of the rotor of Fig.2 - cross on the non-magnetic elements, Fig.3 is a cross section of the ferromagnetic bodies in Fig.4 is a General side view of ferroelectromagnetic.

The rotor of wind power segment includes the wheel hub 1, the blade 2, spokes 3, the rim 4, the ferromagnetic tela, non-magnetic elements 6, screed 7, representing the two retaining element respectively to the right or left-handed, United nut is also provided with right and left threads. The rotor also includes bars 8 couplers 7 and the fastening bolts 9. Thus, fasteners, made of non-magnetic elements are bars with holes for fastening bolts. In addition, the necessary elements are screed 7, also made of nonmagnetic segments of the bars 8 and the non-magnetic rods with nuts.

The rotor operates as follows: when there is wind flow, which exerts pressure on the spokes (the blades), the rotor starts to rotate. Ferromagnetic cores modulate the magnetic flux of the stator. The stator is mounted on the lower end of traverse, which is attached to the moving (rotating) the basis on which also strengthened the bearing and the tail wind power. The stator, like all stators induction generators, constitutes a magnetic circuit, in which, in addition to the magnetic circuit includes the source of the magnetic field of the permanent magnet or the excitation coil and the working coil which senses changes in flow caused by its modulation by the rotor. The induced voltage is then fed to the control unit and then to the load. Nonmagnetic e the cops 6 represent bars, made for example from plastic, provided with holes for the passage of fastening bolts.

Technical and economic advantage of the rotor is that the technology of its implementation implies the existence of such common elements as pieces of pipes.

The rotor segment ferroelectromagnetic containing the hub, the blades, the rim and the ferromagnetic body and non-magnetic elements connected to one another and mounted on the rim, wherein the ferromagnetic body is made in the form of segments of pipe, inside of which is installed fasteners, made of non-magnetic elements, in the form of segments of bars with holes for fastening bolts.
