The invention relates to electric machines, structures of stators and rotors of AC machines. This invention can be used in the design and manufacture of the windings of the stator and rotor induction machines, armature windings of the synchronous machine windings and armature brushless motors. Applicable mainly for low-voltage electrical machines or machines with a large number of poles. Known wave rod winding of electrical machines (Waldek A.I. Electric cars, L., 1978, s - 409). These include rods, located in the upper part of the slots of the core, forming the top layer of the winding and the terminals located in the lower parts of the slots of the core, forming the bottom layer of the coil and the conductors windshields parts located at the ends of the core. The latter include the conductors between the terminals of winding turns, United in winding group, and conductors for connecting winding groups, as well as the conductors of the findings of the phase winding. The end windings are hard and do not have a special turn-to-turn insulation. However, the departure of end parts of the winding is very large. Known winding of the electric machine (rotor) (patent RF №2152117, EN BIPM No. 18, 27.06.2000), containing in the slots of the core is electrically insulated conductors - cores connected short rings - lobby and parts of the winding, made of elementary short rings. The invention reduces the electrical losses in squirrel-cage winding of the rotor from the higher time harmonics voltage when machine power from the source of non-sinusoidal voltage. The disadvantage of this coil is that it can be used only in machines with squirrel-cage rotor. Also known winding of the electric machine (Lytkin CENTURY Way of organizing windshields parts of electrical machines with minimum axial flight. Journal USTU No. 5 (25), Ekaterinburg, 2003. s - 193). It includes rods, located in the upper part of the slots of the core, forming the top layer of the winding and the terminals located in the lower parts of the slots of the core, forming the bottom layer of the winding, and the conductors windshields parts located at the ends of the core, including the conductors between the terminals of winding turns connected in a coil group, and the conductors for the connection of coil groups, and the conductors of the findings of the phase winding. To reduce the departure end parts of the winding is done bending rods at the exit from the slots in the plane perpendicular to the axis of rotation, along the radius direction to the outer diameter of the stator core (stator winding) or to the axis of rotation (phase winding of the rotor). Each winding rod, leaving the PA is and at some distance from the end face of the stator core (rotor) determined by voltage class, double-bent on a line running at an angle of 45 degrees to the axis of the rod along its wide side. Due to the fact that the rod is bent at its wide side, the likelihood of damaging the insulation of the terminals of the winding is substantially lower than in bending rods on the edge, as it occurs in the coils of conventional design in the transition from the top of the rod to the bottom. After the second bend of the rod is in the plane perpendicular to the axis of rotation, and is located along the radial line. The distance between the fold lines is selected so that after two bends the rod passed under the rod, located in the adjacent groove. After that, the rod is bent flatwise or in an arc of a circle or in a straight line, and forms the frontal part winding. Then after two such curves, going in reverse order, the rod moves in the corresponding step of the winding groove. For rods, the conductors which are in a horizontal position, the front part is formed already after two bends. The disadvantage of this winding is a significant departure windshields parts, complex technology of its manufacture, the possibility of making only concentric windings. Also known winding of the electric machine (patent RF №2275729, EN BIPM No. 12, 27.04.2006) closest to PR is delaunoy. This winding of an electric machine, includes rods, located in the upper part of the slots of the core closer to the sockets of the surface of the core, forming the top layer of the winding and the terminals located in the lower parts of the slots of the core closer to the back of the core, forming the bottom layer of the winding, the conductors windshields parts located above the end surfaces of the core, made in the form of frontal jumpers and including a short jumper between terminals forming the coils of the phase winding connected in the winding group, the jumper to connect winding groups located above the front surface of the backrest (yoke) of the core, and the conductors of the findings of the phases connected to the terminals. The sectional area of the front of the jumper, at least in their majority, in connection with rods less averaged over the length of the groove space of cross-sections of connected terminals, and the connections, the front of the jumper to the pins of the upper layer coil located on the side facing the sockets surface of the core, and the joints, the front of the jumper to the pins of the lower layer windings are located on the side of the backrest (yoke) of the core. The location of the connection end of the jumper to the pins at the upper and lower sides of the slots allows you to make space for the placement of the main parts of the winding jumpers on the whole, the Central portions of the grooves and make the connections between the terminals of coils for almost the shortest distance. However, when this jumper for connection of the winding of the winding groups are displaced in the area of the backrest (yoke) of the core. Therefore, the disadvantage of this winding is of considerable length jumper for connection of the winding of the winding groups, and their significant inductive and active resistance, which leads to an increase in the mass of copper winding losses increase and decrease the torque of the electric machine. The technical result is the reduced mass of copper windings, reduce losses and increase the maximum torque of the electric machine. The technical result is achieved by the fact that the winding of the electric machine, including rods, located in the upper part of the slots of the core closer to the sockets of the surface of the core, forming the top layer of the winding and the terminals located in the lower parts of the slots of the core closer to the back of the core, forming the bottom layer of the winding, the conductors windshields parts located above the end surfaces of the core, at least most of them made in the form of frontal jumpers, including a short jumper between terminals forming the coils of the phase winding connected in the winding group, the jumper to connect winding groups and the conductors of the findings of the phases connected to the rods, square section at least most of them in the hundred of their connection with rods less averaged over the length of the groove space of cross-sections of connected terminals of the winding, made so that the windshield jumper to connect winding groups are located above the end surface of the sockets of the core zone with the part of the slots where the layer winding, the terminals of which they connect, joints winding windshields jumper from terminals in layer windings, which are frontal jumper for connection of the winding groups are from the centers of the slots of the core, and the connections of at least a majority of the other end of the jumper to the pins of the upper layer coil located on the side facing the sockets surface of the core, and the connections of these windshields jumpers to the pins of the lower layer coil located on the side of the back core. A specific example of the invention is illustrated by the design of the active part of the stator three-phase electrical machine is presented in figure 1, 2, 3, 4. Figure 1 shows the conceptual layout of the active part of the stator 1 of an electric machine, which includes the core 2 with the slots 3. The core has a backrest 4, subsoul zone 5 with the sockets surface 6 and the end surfaces 7 and 8 of the sockets zone. In the slots of the core is a three-phase winding 9 with conductors of the findings of phase 10, made in accordance with the proposed technical solution. Figure 2 shows the scheme of the three-phase winding 9, sootvetstvuyshee conceptual layout, presented in figure 1. Indicate on the diagram correspond to the technical literature, for example - Waldek A.I. Electric cars, L., 1978, s-499. As can be seen, the stator core has twelve slots that are numbered in the centre of the figure in the direction of phase rotation. Solid lines in the slots marked the rods 11 of the upper layer of the winding, and the dashed - rods 12 of the lower layer. Figure 2 shows also short windshield jumper 13 connecting the separate cores of the coils 14, and also shows a frontal jumper 15 (thick dashed lines)connecting the winding group. The findings of the 10 phases of the stator winding shall have the following legend: the beginning and the end of the first phase, denoted by U1U2, the beginning and the end of the V1V2third - W1, W2. This scheme corresponds to the four-pole three-phase wave rod winding with diametrically step. Figure 3 shows the active part of the stator 1 with the proposed winding 9 (figure 1) from the findings of phase 10 of this winding. The grooves 3 are numbered in a circle, depicting the inner surface of the core 2. Shows a cross section of rectangular shape 16 of the slots 3. In the upper part of these grooves, closer to the sockets surface 6 of the core 2, are the rods 11, the upper layer of the winding 9, and the bottom parts of the grooves 3 of the core 2, the closer to the back 4 of the core 2,are the rods 12, forming a lower layer of the winding 9. The frontal part of the individual phases is highlighted by shades of gray. Figure 3. shown front short jumper 13 connecting the terminals of the coils, as well as windshield jumper 15 connecting the winding group phase located above the end surface 7 of the sockets zone 5 of the core 2. Cross-sectional frontal jumpers 13 and 15 in connection with the rods 12 of the lower layer coil in half the space of cross-sections of connected terminals, and the sectional area of the front of the jumper 13 in connection with the rods of the upper layer 11 is equal to the squares of the cross-sections of connected terminals. Each of the conductors of the findings of phase 10, for example the conductor end phase U2, has the cross-sectional area 17, for example, in connection with the rod located in the upper layer of the fourth groove, two times the smaller cross-sectional area of the rod with which it is connected. In the case of joining the conductors of the findings of the phase 10 to the terminals of the upper layer 11, as shown in figure 3, the connections short windshields jumpers 13, with the rods 12 of the lower layer winding, over which are frontal jumper 15 for connection of the winding groups are from the centers of the slots of the core. In the case of joining the conductors of the findings of the phase 10 to the terminals of the lower layer 12, the connections short windshields AC the cheque 13, with the rods 11 of the upper layer of the winding, over which will be a head-jumper 15 for connection of the winding groups, will also be located from the centers of the slots of the core. I.e. joints winding windshields jumper with 13 terminals or 12 And the layer windings, which are frontal jumper 15 for connection of the winding groups are from the centers of the slots 3 of the core 2, regardless of the layer winding, is connected to the conductors of the findings of phase 10. Figure 4. shows the active part of the stator 1 of an electric machine with the proposed winding 9 (figure 1) from the end, where there are no findings of phase 10. The numbering of the slots 3 along the inner circumference corresponding to the sockets of the surface 6 of the core 2, made in accordance with figure 2, 3. Shows short windshield jumper 18 phase U, short windshield jumper 19 phase V and short windshield jumper 20 phase W, located on the end surface of the sockets zone 8 of the core 2. The sectional area of the front of the jumper 18, 19, 20 in connection with the rods 12 and 13 of the winding 9 in half the space of cross-sections of connected terminals. Joints winding windshields jumpers 18, 19, 20 with the terminals of the upper layer of the winding 11 are from the sockets surface 6 of the core 2. Joints windshields jumpers 18, 19, 20 with the terminals 12 of the lower layer on ODI 9 are located on the side of the backrest 4 of the core 2. Works proposed winding 9 in the active part of the stator 1 three-phase electric machine as follows. Phase winding 9 connected in star (unite conclusions U2V2, W2.), or in the triangle (connect U2V1V2with W1, W2with U1). Motoring on the findings of the phase winding 9 serves a three-phase voltage source AC. In phases U, V, W winding 9 occurs three-phase system of currents, which forms a rotating magnetic field in the core 2, as the axis of the phase windings 9 are shifted in space by 120 electrical degrees (see figure 2). If inside the active part of the stator 1 with the proposed winding 9 is the rotor, for example, a squirrel cage winding, the core also occurs rotating magnetic field, and it will start to rotate under the action of electromagnetic torque created by the interaction of a rotating magnetic field and currents in the rotor winding. Possible operation of the electrical machine with the proposed winding 9 in the generator mode. In this case, the rotation of the magnetic field in the magnetic core of the electric machine, for example, created by the rotation of the electric machine rotor with permanent magnets, will lead to the formation of the proposed winding three-phase EMF. When connecting to the leads of the winding system is coy machine consumers of electricity, AC, mechanical energy is supplied to the shaft of the electric machine is converted into electrical energy that is transmitted to these consumers. Thus, the proposal is workable in motor and generator mode of the electric machine, allows to reduce the length of the front of the jumper for connection of the winding groups of the winding of the electric machine, which reduces the mass of the copper winding. Reduced resistance of these jumpers, and, therefore, reduces the loss in the winding. Also reduced and inductive resistance of conductors for connection of the winding groups due to the fact that these wires are located above the end surface of the sockets of the core zone having a lower average magnetic permeability. The decrease in magnetic permeability of the surface, on which are located windshield jumper to connect winding groups, leads to the reduction of their inductance. The reduction of active and inductive resistance of the stator winding leads to an increase in maximum torque, for example asynchronous machine (Waldek A.I. Electric cars, L., 1978, s). Thus, the proposed winding of the electric machine allows you to perform the connection between the terminals of the shortest distance between them, allowing to reduce the mass of the IU and winding, reduction of power losses in the winding and increase the maximum torque of the electric machine. The winding of the electric machine, including rods, located in the upper part of the slots of the core closer to the sockets of the surface of the core, forming the top layer of the winding and the terminals located in the lower parts of the slots of the core closer to the back of the core, forming the bottom layer of the winding, the conductors windshields parts located above the end surfaces of the core, at least most of them made in the form of frontal jumpers, including a short jumper between terminals forming the coils of the phase winding connected in the winding group, the jumper to connect winding groups and the conductors of the findings of the phases connected to the rods, the cross-sectional area of at least most of them in connection with rods less averaged over the length of the groove space of cross-sections of connected terminals of the winding, characterized in that the frontal jumper for connection of the winding groups are located above the end surface of the sockets of the core zone with the part of the slots where the layer winding, the terminals of which they connect, joints winding windshields jumper from terminals in layer windings, which are frontal jumper to connect winding groups, whic is ogeny from the centers of the slots of the core, moreover, junctions, at least a majority of the other end of the jumper to the pins of the upper layer coil located on the side facing the sockets surface of the core, and the connections of these windshields jumpers to the pins of the lower layer coil is situated towards the back of the core.
