According to the figure 1 circuit vosmipolosnoy stator winding induction generator contains 24 reel group (1...24) with the output 25 from the United 1 start and end of the 6 coil groups, with the output 26 from the combined end 2 and start 3 coil groups, with the output 27 of the combined end 4 and early 5 reel groups, with the output 28 from the United late 19th and early 20th coil groups, with the output 29 from the joint end 21 and the beginning 22 of coil groups, with the output 30 from the combined end 23 and the beginning of the reel 24 groups, while the end of the 1 coil group is connected with the beginning of the reel 7 group, beginning 2 end 8, the end of the 3 - since the beginning of 9, top 4 - with the end of 10, the end of the 5th - beginning of the 11th, the start of the 6 - with the end of the reel 12 group, late 7th - early 13th, beginning 8 with the end 14, the end of the 9th - beginning of the 15th, the beginning of the 10 - with the end 16, the end of the 11th - beginning of the 17th, the beginning of the 12 - end 18, the end of the 13th - beginning of the 19th, beginning of the 14 - end 20, the end of the 15th - beginning of the 21st, the beginning of the 16 - end 22, the end of the 17th - beginning 23, beginning 18 reel group is s with the end 24 of the coil group.

According to figure 2, the excitation capacitors 31, 32, 33 are included in the conclusions 25, 26 and 27. At idle generator magnetic flux from the magnetizing currents (figure 5) iµA, iµB, iµCinduces the conclusions (25 and 26) and (28 and 29), for example, the phase winding And the same magnitude of the EMF E25-26and E28-29offset at an angle of 60° (figure 4). In figure 3 the sides of the coils of phase a are indicated by squares, phase triangles and phase With circles (marked and the location of the conclusions). As the conclusions 25 and 26, and the conclusions 28 and 29 phase zone is 120 electrical degrees.

According to figures 6-8 enabling active load 34 on the conclusions 28, 29, 30 vector sum of the currents of excitation and load parts of the phase winding (for example, phase a) are different values. At diametrically the spacing of the sides of the coils of the parts of the phase windings, with big and small currents in the same grooves allows the coil parts of the winding wire of different cross-section, which to a certain level load level (50-60%) contributes to considerable reduction of losses in the stator windings.

Asynchronous generator with vosmipolosnoy stator winding operates as follows. When the rotor of the asynchronous generator with a speed higher than the speed of rotation of the magnetic field due to the residual namini the air traffic management and excitation capacitors 31, 32, 33 is in the process of self-excitation of induction generator.

At idle asynchronous generator stator windings flows capacitive magnetizing current iµA, iµB, iµC. This current creates a magnetic flux that induces the conclusions (25 and 26) and (28 and 29), for example, the phase winding And the same magnitude of the EMF E25-26and E28-29offset at an angle of 60°.

When turning on the load, for example, to conclusions 28, 29, 30 in addition to the magnetizing current iµA, iµB, iµCyou receive the load current iA, iB, iC(figure 6 and 7).

The load current and the excitation current in parts of the phase winding are different values (figure 8). This allows the coil parts of the winding wire of different cross-section, which to a certain level load level (50-60%) contributes to considerable reduction of losses in the stator windings.
