The invention seeks to simplify manufacturing and increase use of active materials, while reducing input of insulating materials and coefficient of differential scattering σd% m=3-phase 2p1=6·k- and 2p2=8·k- pole lap windings of a stator in z=144·k slots. The essence of the invention lies in that, the double-winding stator of an asynchronous motor has m=3-phase 2p1=6·k- and 2p2=8·k-pole lap windings in z=144·k slots, each of which is made symmetrical from m=6-zone from equally spaced coils, put into the slots in two layers. According to this invention: from K=z coils with numbers from 1K to (z)K, the 2p1 pole winding relates to K/2 coils with odd numbers 1K, 3K,…(z-1)K, containing wK1 turns and connected into 6p1 coil semi-groups with q'1=4 neighbouring coils in each. The 2p2 pole winding relates to K/2 coils with even numbers 2K, 4K,…,(z)K, containing wk2 turns and connected into 6p2 coil semi-groups with q'2=3 neighbouring coils in each. All coils have uneven spacing in the slots, equal to yk=19, or yk=21, where k=1, 2 given q'1=z/12p1 and q'2=z/12p2.

The invention relates to three-phase windings of the stator of a two-speed AD (asynchronous motors with squirrel-cage rotor.

Known symmetric loop two-layer (single-layer) m=3-phase 2P-pole winding is performed in the z grooves of the m p of coil groups (semigroups) in increments of their coils in the slots of thetoclose to the pole division τp=z/2p, the number of slots per pole and phase q=z/m p and phase zones on a couple of poles m'=6 (zones A, Z, B, X, C, Y) [Waldek A.I. of the Electric machine. L.: Energy, 1978, s]. When integers q each coil group contains q adjacent coils, and when the fractional q=z/m p=N/d=b+c/d (for numbers d not divisible by m). the number of coils in groups correspond to the grouping of the winding in the form of a numerical range defined by the fractional part of s/d number q [Livshits-Garik M Winding AC machines / Lane. from English. HP: SEI, 1959, s].

On the two-speed stator HELL when the ratio of speeds 3:2, 4:3, etc. are usually two separate opposite-pole three-phase winding is performed in a conventional two-layer loop-forming after laying four slot layer, which increases the flow of insulating materials and increases the slot scattering winding placed at the bottom of the slot layers. Both windings can be performed similarly to the single-layer chain at the location of their groove and windshields parts in two layers [Sergeev Psi other Proektirova is their electric cars. M: Energy, 1970, s-453].

The invention seeks to simplify manufacturing and improve the use of active materials while reducing the consumption of insulating materials, grooving and differential σd%, scattering m=3-phase 2p1=6·k - 2P2=8·k-loop pole windings at z=144·k the slots.

The solution of this problem is achieved by the fact that for the stator with m=3-phase 2p1=6·k - 2P2=8·k-loop pole windings in the z=144·k slots, each of which is made symmetric m'=6-zone of uniformly interleaved coils placed in the slots in two layers: K=z coils with numbers from 1 K to (z)K 2P1-pole winding refer To/2 coils with odd numbers 1K,3K,...,(z-l)K, with wK1coils and connected in 6p1reel semigroups with q1'=4 adjacent its coils in each, and to 2P2-pole winding refer To/2 coils even numbered 2K,4K,...,(z)K, with wK2coils and connected in 6R2reel semigroups with q2'=3 its neighboring coils in each, all coils have an odd step grooves equal into=19 or yto=21, where k=l, 2 if q1'=z/12p1and q2'=z/12p2.

Figure 1 shows the scan-lock layers of the proposed two-winding winding stator at z=144(k=l), yto=19 z/2=72 slots with the numbers of the slots 1...72 SNES is, coils 1K,2K,... top with phase zones A-Z-B-X-C-Y layers for 2P1=6-pole winding with q1=8 (the odd-numbered coil), A'-Z'-B'-X'-C'-Y' for 2P1=8-pole winding with q2=6 (even-numbered coil) and the top shows the frontal part of the coils 1K and 2K, in figure 2 the phase alternations zones 1, a triangular grid (at her side in two units of length) constructed polygons MDS for 2p1=6 (outer), 2P2=8 (internal) with the numbering of the first q1=z/6p1=8, q2=z/6p2=slot 6 points with unit vectors of currents zones A-Z-B-X-C-Y center; figure 3, like figure 2, constructed polygons MDS for step coils Into=21. When k=2, the winding has 2p1=12 and 2P2=16 poles at z=288 grooves.

Winding of figure 1 are connected to the usual m'=6-slice winding way, i.e. semigroups zones X, Y, Z are included in the phase counterpart of semigroups zones a, b, C, and phase must match the star. Side coils take on 1 half of each slot, but can have a large section for one and correspondingly smaller for the other windings with different numbers of turns wtoand conductor cross-sections of their coils. Such winding, such a chain of single-layer, obtained as if embedded in one another when the two layers for grooving and windshields parts, which reduces the flow of insulating materials and grooving reduces scattering. For large Adaudience coils heteropolar parts can be run on opposite sides of the stator.

The differential scattering coefficient σd%is determined from the polygon MDS winding using a triangular mesh [Popov V.I. Determination and optimization of parameters of three-phase windings on their polygons MDS)//Elektrichestvo, 1997, No. 9, p.53-55] ratios

where R2d- the square of the average radius for j=1...N=q·d slot points one recurring part of the polygon; R2jdetermined by the law of cosines.

2P1=6-pole winding 1 when q1=z/6p1=8, τp=24, yto=19 has the coefficients: shortening coils Ky=sin(90°19/24)=sin(71,25°), distribution To thep=0,5/4sin7,5° and winding Toabout=KyTop=0,90684. On the outer polygon MDS figure 2: R2j=3·82=192 for (j=1; R2j=102+62+10·6=196 for j=2,8; R2j=122+42+12·4=208 for j=3,7 R2j=122+22+12·2=172 for j=4,6; R2j=142=196 for j=5, R2d=ΣR2j/8=192.5 kg (1), Ro=144·0,90684/3π and σd%=0,274. For 2P2=8 if q2=z/6p2=6, τp=18 for internal polygon MDS figure 2: Ky=sin95°, Kp=0,5/3sin10°, Kabout=0,95614 and R2d=ΣR2j/3=724/6, Ro=144·0,95614/4π and σd%=0,517. Similarly for yto=21 Magog is linkam MDS figure 3: 2p 1-Kabout=0,93926, Rd2=206,5 and σd%=0,269;

2P2-Kabout=0,9271, R2d=680/6 and σd%=0,415, i.e. the choice of the step into=19 or yto=21 is determined by the design and capacity two-speed HELL.

The application of the proposed windings on the stator HELL with two-speed squirrel-cage rotor can simplify manufacturing, reduce consumption, insulating materials, to improve the electromagnetic parameters of the windings due to the reduction of their groove and differential scattering in comparison with the conventional separate opposite-pole single - and double-layer windings.
