The invention relates to the field of wind energy.

Known wind power generators [1, 2] with the stators of the traditional type, including those containing T-shaped and W-shaped yokes and coils, as well as fastening elements.

Of all known analogues closest to the claimed combination of essential features is the stator wind power [3], segment type, which is based on the magnetic system of the machine DC or universal, and includes a base, a coil, a source of magnetic field and magnetic circuits. Two rotor - propeller installed with the possibility of magnetic contact with the core.

The disadvantage of this stator is that it is adapted to work only with pre-cut diameter inducer, which complicates the manufacturing technology that increases weight.

The invention is aimed at improving the manufacturability and reliability.

This is achieved in that the stator wind power synchronous type, containing a base, fasteners, T-shaped and W-shaped yokes and coils, according to the invention the stator is made in the form of two parallel T-shaped cores, the ends of which are connected W-shaped magnetic core in such a way that the edge of its Gori is ostalnoe jumpers connected to the ends of the vertical posts of the T-shaped magnetic circuits, and vertical racks W-shaped magnetic core covered by additional coils.

The invention is illustrated in the drawing, in which figure 1 shows the claimed stator, front view, figure 2 - side view.

The stator wind power synchronous type comprises a base 1, W-shaped magnetic core, which consists of vertical and horizontal struts 2 jumper 3, two T-shaped magnetic circuits, each of which consists of vertical posts 4 and the horizontal part 5. The stator is in contact with the rotary element, which consists of corner pole pieces 6 and the source of the magnetic field 7 (for example, a permanent magnet). A rotor element mounted on the end of the blade 8. The stator is provided with a main coil 9, covering the vertical posts 4 T-shaped magnetic circuits. The ends of these bars 10 by means of bolts 11 are fixed to the base 1 so that the horizontal crosspiece 3 is above the vertical posts 2. Rack 2, in turn, covered by the coil 12. The stator and rotor are separated by an air gap 13.

The stator operates as follows: when the rotation of the windwheels rotary elements that are attached to the blades periodically enter into magnetic contact with the adjacent strip-magnetic - horizontal sections 5 of the T-shaped magnetic circuits. In d is the query result in the coils 9 induced EMF, which is passed on to the consumer. The magnetic flux is closed through the circuit: - right corner of the magnetic core 6, an air gap, the right horizontal section 5, vertical posts 4, the horizontal crosspieces 3, again vertical posts 4, the T-shaped magnetic core (left), the left horizontal section 5, the air gap, the left corner of the magnetic core, the source of the magnetic field 7.

A feature of this stator is that in addition to the main flow through the uprights 2 and the coil 12 can use ripple flux arising from the closure and opening of the magnetic circuit and caused the fall of the magnetic potential on the horizontal crosspieces 3.

Feasibility advantage of the stator is its high technology based on the use of windings of the coil type, as well as on the use of common T-shaped and W-shaped yokes. In addition, instead of the W-shaped magnetic core is permissible to use the U-shape, i.e. the same W-shaped without vertical middle rack, or one wide T-shaped, i.e. the same W-shaped without the two outer uprights, however, the number of additional coils 12 is reduced.
