    05 1 The invention relates to electrical engineering, in particular to a three-phase coil of alternating current of an inductor of a linear electric motor. The three-phase winding of an alternating current of a linear electric motor, the motor, having separate branches formed of three cables by laying them into the slots of the inductor Cl 3 is known. This winding is characterized by inadequate operating reliability due to the presence of high longitudinal stresses. The closest to the technical essence of the invention is the three-phase winding of an alternating current of a linear motor inductor, having separate branches, bonded to each other, formed from three separate cables by preliminary shaping on the model corresponding to the inductor, by laying them into the grooves of the layout, bending it ends with the formation of frontal parts, and which in parallel sections have a constant distance corresponding to the distance of the grooves from each other C2L This technical resolution is characterized by insufficient reliability in operation due to the presence of high longitudinal stresses. The purpose of the invention is to increase the reliability of operation by eliminating high longitudinal stresses. The goal is achieved by the fact that in a three-phase winding of an alternating current of an inductor of a linear electric motor, having separate branches, fastened to each other, formed from three separate cables by preliminary formation on the layout corresponding to the inductor, by bending them into the grooves of the layout, bending around its ends with the formation of frontal parts, and which on parallel sections have a constant distance corresponding to the distance of the slots from each other, the winding cables have an outer sheath of electrically conductive material, the winding is wife at least one metallic uninsulated conductor disposed in the zone of winding heads along the inductor and electrically connected to the cable sheath wet wei winding, wherein said meta-crystal uninsulated conductor is grounded. 6 In FIG. 1 shows a linear electric motor inductor with a three-phase AC winding; in fig. 2 - connection of the winding branches with a metal non-insulated conductor; in fig. 1 is a cross section of an electrical cable. The three-phase AC winding branches are formed by three cables 1,2 and 3 by pre-shaping on the layout. The finished winding is laid in the slots of the inductor 4, while the winding branches in parallel sections have a constant distance corresponding to the distance of the slots from each other. The winding is provided with at least one metallic non-insulated conductor 5 located in the zone of the winding frontal parts along the inductor. The winding can also be provided with a second non-insulated conductor 6, also placed in the area of the frontal parts and fastened to the cables with the clips 7. I The electric cable that can be used for winding has the structure shown in FIG. 3. An inner conductive layer 9 is applied to the conductor 8 to align the conductivity. Around this inner conductive layer is an insulator 10 surrounded by an outer conductive layer 11. The outer conductive layer has, for example, a resistance value of 400 ohms / m. On the outer conductive layer is an outer sheath 12 of electrically conductive material. Conductors 5 and 6 are electrically connected to the sheath of 12 cables and grounded. Conductor 8 can be made of copper or aluminum. Here we can talk about a massive conductor (vein), a sectoral conductor or a stranded conductor. All that matters is that the cable should lower the possibility of light forming in the winding branch, and then retain its shape. Insulator 10 may, for example, consist of ethylene-propylene rubber. For example, polyvinyl chloride or polyurethane, made electrically conductive by mixing carbon black, graphite or metal powder, can be used as a material for the wall covering. The shell should have a resistance value of about 100 ohms / m.
    Since the cables must be laid in grooves with sharp edges of the inductor 4 and in the area of the frontal parts, the winding after laying is not specially protected, a protection consisting of mechanically solid insulating material can still be applied to the outer jacket. This protection can, for example, be made in the form of tapes, which are wound around the cable with gaps so that sheath 12 remains available for contact with branches 5 and 6. However, sheathing can also be made into sheath material 12.
