The invention relates to windings of electric machines of alternating current with two opposite-pole fields in a common magnetic core.

The purpose of the invention is to expand the field of application of the winding by obtaining 16 ± 6 with the phase numbers m, / m, 1/4.

does not induce an emf at terminals A (see FIG. 2), and a field with p leads for emf at terminals 01-02 i.e. opposite-pole igniters are electromagnetically independent, a balancing current flows. Its winding cables are equal for P, 16 - K „5

FIG. 1 shows a diagram of the winding Q for p - 6 - K OB $ 0.906.

ki in FIG. 2 is an emf diagram for polarity p, 16; FIG. 3 - the same for p polarities, 6.

The winding (fig. 1) is single-layered in 32 slots of 16 coils (with numbers from 1 to 16) with a step along the slots of 3 C, 3, where -C, 32/32 1 pole division for p, 16 It is connected in four branches with numbers sequentially according to the included katuk NIS 1,4,13,16 in the first 3,6,15,2 in the second 5,8,9,12 in the third 7,10,11,14 in the fourth branches. The beginnings and the ends of the branch form a single-phase clamps 01-02 for polarity p 16, and the leads from their midpoints are additional four-phase clamps A, B, C, D for p, j 6. In FIG. 1, the upper row of arrows shows the directions of single-phase current when powering the winding through clamps 01-02 (p, 16), and the lower row shows voltage 4-phase current when feeding the winding through clamps A, B, C; -D ( Rg 6). FIG. 2 and 3 EMF vectors are assigned numbers of coils shifted by angles: for p, 16 - (360/16) 16 for p 6- (360 / 1b) 6 360/8) 3 °, which is on the EMF diagram for p, j - 6 provides alternation

phases in the sequence A-B-C-D to JQ tripled pole division for clockwise. A field with an RA of 16 poles of p.

does not induce EMF at terminals A, B, C, D (see FIG. 2), and the field with p 6 does not induce EMF at terminals 01-02 (see Fig. 3) i.e. opposite-pole ignition windings are electromagnetically independent and, therefore, equalizing currents in it do not flow. Its winding coefficients are equal for Р, 16 - К „5, 1.0,

for p - 6 - OIL $ 0.906.
