The purpose of the invention is to expand the field of application of the winding by obtaining the number of phases for the polarity of p2t2 5. The winding is made of ten evenly displaced spools and connected in parallel with single-phase clamps for polarity pi and with additional clamps for polarity p2 from their midpoints-. The spools are connected in series in the five branches with numbers 1 and 6 in the first branch, where the minus sign means counter inclusion in the branches.

FIG. 1 shows a winding diagram with 5/2; in fig. 2 and 3 are its EMF plots for PI 5 and p2 2, respectively; in fig. 4-6 is the same as in FIG. 1-3, y

but for winding with PI / P2 5/4.

The winding (FIGS. 1 and 4) is made single-layer in 20 slots of ten coils (with numbers from 1 to 10) with a step along the slots “T2 5 for FIG. 1 and UE T | + 1 3 dl.

FIG. 4, where TI and T2 are pole delays-1 5 with pi / p2 5/2 polarity, made of for PI and p2. The coils are connected in fifty evenly mixed coils and

branches with numbers 1 and -6 for the first branch, connected in parallel branches, the beginning

and for each subsequent branch, the number and ends of which form single-phase coils alternate relatively previous for zero pi, and the additional branch with two coils spacing, 2p clamps for polarity p2 are made where the minus sign means its opposite on-off from the mid-points of the parallel branches, characterized in that, in order to expand the field of application by obtaining the number of phases for the polarity of p2t2 5, the coils are included in five branches with numbers 1 25 and -6 in the first branch, and for each subsequent branch the number of coils alternate from relative to the previous branch with interruption in the branch. The beginnings and the ends of the branches form the clamps 01-02 for pi 5, and the leads from their midpoints are the additional five-phase clamps A, B, C, D, E for polarity p2. FIG. 1 and 4, the upper row of arrows shows the directions of the single-phase current when the winding is supplied through 01–02 (PI 5), and the lower row shows the directions of the four-phase current when the winding is supplied through A, B, C, D, E. In FIG. 2 and 3, 5 and 6, the EMF vectors are assigned numbers of coils.

Scrap into two coils and their groove step is equal to pole division for P2 polarity, where a minus sign in front of the coil number means that it is included in the branches.

whence it is clear that the field with pi 5 does not induce an emf at the terminals A, B, C, D, E (see Figs. 2 and 5), and a field with a polarity of p2 does not induce an emf at the terminals 01-02 (see Fig. 3 and 6). Winding factors are: for

FIG. 1 - Cobs 0.707 and Cob2 1.0; for figs. 4 Kob5 0.707 and Kob4 0.951. Wrap-up, in contactless co-mix, dual-feed machines, etc.
