    The stator of a linear motor is assembled by separately assembling the windings as a uniform configuration, using a dummy to place cables into requisite positions and tieing the resulting coil ends together by end elements. The dummy is of an endless belt variety and is used to assemble the stator winding configuration in endless type fashion. The resulting assembly is placed into the stator core or cores which have been placed along the contemplated track part along which the motor is to move a vehicle or the like, carrying the armature of the motor.

    (54) THE METHOD OF MANUFACTURING THE THREE-PHASE LINEAR AC MOTOR INDUCTOR AND WINDING
    The invention relates to electrical engineering and can be used in the manufacture of inductors of linear electric motors. A known method of manufacturing a core of an electric machine consists in prefabricating a winding by bending the conductor and forming a rigid interconnected structure, which is then fixed on the surface of the core tl. The closest to the present invention is a method of manufacturing a three-phase linear alternating current inductor with an alternating current motor, in which the separate phases of the winding are placed in the slots of the inductor, bending the ends of the core / M to form the frontal parts, and fasten. The disadvantages of this method are the large labor costs associated with the manufacture of the inductor, which increases with the increase in the size of the inductors, and the work associated with laying the conductors into the grooves of the inductor is only performed by a highly qualified specialist. The purpose of the invention is to simplify the preparation and increase the accuracy . The goal is achieved by the fact that when manufacturing an inductor of a three-phase AC linear motor with a winding, prior to laying the winding into the grooves of the inductor, it is molded on a model that corresponds to the inductor and consists of an endless ribbon with grooves and two walls separated from it by notches In the layout at the location of the frontal parts, the lower fastening elements are placed in the grooves of the layout of the winding phase, made of isolated electrical oscillations, placed on the frontal parts. The parts of the upper fasteners and connect the upper and lower fasteners among themselves, after which the winding is removed from the layout. In addition, the winding after it is formed on the layout and superimposed on the frontal parts of the fasteners is removed from the layout and wound on the drum. FIG. 1 schematically shows a linear motor; in fig. 2 linear motor inductor J
    view from above; in fig. 3 - formed winding with fastening elements superimposed on the frontal parts.
    The inductor 1 of a linear electric motor is made of a ferromagnetic material, in the slots 2 of which winding 3 is placed, creating a traveling magnetic field. The mobile part 4 separated from the inductor 1 by an air gap is placed in a weave that can move during engine operation, for example, in the direction of arrow A. The movable part 4 is filled, for example, from copper or aluminum or permanently magnetized material and can be fixed to the vehicle in order to move in a given direction.
    Winding 3 consists of three phases 5-7. These phases of the winding consist, for example, of medium or low voltage cables and have a phase conductor made of copper or aluminum flux. On top of this phase conductor is a leveling layer and, in addition, a suitable insulation of heat-resistant plastic. Above this plastic layer, if necessary, another conductive layer can be placed.
    In the manufacture of winding 3, first of all, all three separate cables are laid as phases 5-7 of the winding into layout 8, reproducing u, the stator 1 with its grooves. This layout consists of an endless chain on which the blocks 9 are placed, separated from each other by gaps corresponding to the dimensions of the grooves 2 in the stator 1. The endless ribbon of the layout 8 can pass between the walls through two rollers and thereby separate phases of the winding are placed in the top between the blocks 9, the gaps are reliably connected to each other in the frontal parts of the winding and then continuously withdrawn from the moving further breadboard 9, at the same time new coils are placed into the next gaps between the blocks 9.
    According to FIG. 2, in this case, phase 7 is first laid out, then phase 6 is laid in the gap between blocks 9, and provided for it.
    When laying individual winding turns, the frontal parts 10, which are located outside the grooves, are laid as tightly so that they do not protrude far away from the injector 1 in the finished electric motor. Since the frontal parts of the winding 10, due to the elasticity of the cables used, cannot retain the shape shown in FIG. 2, they are rigidly connected to each other by special auxiliary means. These special tools are shaped parts 11 of mechanically strong material, construc. The hands of which are shown in FIG. 3. Parts 11 are laid into the grooves between the blocks 9 and the walls of the layout 8. Since the shaped parts for matching the frontal parts of the winding 10 are provided with rounded guides, C1 air channels are formed C1, consisting of the gaps between the blocks 9 and and the guides. B. These channels are stacked in phase 5-7 of the winding. The shaped parts 11, which respectively cover the two frontal parts 10, both of which are simultaneously fixed and mechanically protected. After laying the phases of the winding, the fittings are closed with catch / extra / ha parts 12, which are shown in fig. 3 are shown as separate parts. FIG. 2, the shaped parts 11 are shown still open at the top, and in FIG. 3, the structure is already depicted with the shaped parts 11, closed by protective parts 12, which not only overlap the parts 11, but also are rigidly connected to them, for example by gluing or soldering.
    After the winding phases are laid in the layout in the manner described, the layout moves further in the direction of arrow B, and the ready parts of the winding are removed from the layout and thereafter other turns can be laid in the next intervals between blocks 9 and the following fittings 11. Thus, in a continuous process, a very long preformed three-phase winding of a preformed shape is obtained, the length of which is determined only by the length I1 1: that is in the cable arrangement or by the capacity of the drum to which the winding should be wound. The implementation of this winding process does not interfere with shaped and LIA 11, which serve to stabilize and protect, since they cover respectively only two frontal winding parts, and thus a device is obtained which can be compared with a link chain.
    The finished winding after completion / manufacture can be either directly placed in the slots 2 of inductor 1, as shown in FIG. 3, or in the case of a very large length, it can be wound on a baraba.n. From this drum, the winding can be removed again and then in place in the grooves of inductor 1,
    The advantage of the proposed method lies in the fact that, due to the use of a prefabricated and prefabricated winding, the production of an inductor motor is made incomparably simpler. This job can be done by any trained utility.
