    The invention relates to manufacturing equipment for the manufacture of electrical machines and can be used in electrical engineering. . A well-known installation for soldering the winding to the collector of an electric machine, containing a device for gripping, moving and fixing the core with the collector, a bath with molten solder, a single-phase magnetohydrodynamic pump with a supercharger positioned completely relative to the hollow cylindrical magic of the ground wire that has a bevel on the upper end, and heaters . The soldering of the ends of the wires of the windings to the collector plates is carried out by the flow of fused solder in the annular channel formed between the upper part of the supercharger and the beveled part of the magnet wire of the magnetohydrodynamic pump. The known device can be used to solder the winding to collectors of a limited diameter range, which limits its technological capabilities (Zimin V.Is and others. Windings of electrical machines. State Energy Publishing House, 1961, p. 398-400). The aim of the invention is the expansion of technological capabilities. The goal is to achieve that the installation for soldering the winding to the collector of the electric machine, containing a device for gripping,. displacement and fixation of the core with a collector, a single-phase magnetohydrodynamic pump with a supercharger and a bath with molten solder and heaters, equipped with a sleeve made in the form of a hollow cylinder with a conical bottom and a central orifice installed at the bottom of the bath and rigidly connected with it, and a replaceable striz device, consisting of two rigidly interconnected parts — an outer and an inner; the outer part is made in the form of a hollow cylinder located inside the sleeve and pressed to its bottom with a locking joint, the upper The hollow cylinder is bent at an angle to the axis of the device and provided with a visor located above the end surface of the liner with its overlap, and the inner part is made in the form of a hollow cylinder with a conical bottom and a bevel on the outer surface of the upper end of its parallel unbent inner surface of the outer part and located in such a way that, together with the bent inner surface of the outer part, it forms an annular channel located at an angle to the collector axis, and the lower end of the inner part of the replaceable jet mouth oystva and bottom sleeve form a converging tube wherein the supercharger is located under the tub, a magnetic circuit of a magnetohydrodynamic pump is mounted in the plenum, the plenum is connected to the input of the bath bottom, and an output - to the sleeve. In addition, the supercharger has a horizontal section, and a single-phase magnetohydrodynamic pump magnetic circuit is located in this section, the lock connection is bayonet-shaped, the external cylindrical visor of the replaceable jet device is angled to its axis, the end of the magnetic circuit located in the supercharger is streamlined and the inlet of the supercharger is made with a gradually decreasing cross section. The drawing schematically shows the proposed installation. Under the bath 1 with resistive heaters 2 there is a single-phase magnetohydrodynamic pump with a winding 3 and a magnetic core 4 located inside the blower 5 installed under the bath 1. The entrance of the blower 5 is connected to the bottom of the bath 1, and its output through the wheel 6 on which resistive the heaters 7 are connected to the sleeve 8 rigidly attached to the bottom of the bath. The sleeve 8 is made in the form of a hollow cylinder with a conical bottom and a central hole. A removable jet device 10 consisting of two rigidly interconnected parts — an outer and an inner — is clamped to the bottom of the sleeve 8 by means of a locking connection, for example, a bayonet. The outer part is made in the form of a hollow cylinder 11 located inside the sleeve, the upper end of the tube is bent inward at an angle to the axis of the device and provided with a visor located above the end surface of the sleeve 8 with its overlap. The collector 12 is located in the inner part of the replaceable jet device.
    made in the form of a hollow cylinder 13 with a conical bottom and a bevel on the outer surface of the upper end, parallel to the bent inner surface of the lower part.
    The lower end of the inner part of the replaceable jet device 10 and the bottom of the sleeve 8 form a confuser 14. The bevel on the outer surface of the upper end of the cylinder 13 is arranged so that, together with the bent inner surface of the outer part, they form an annular channel 15 located at an angle to the collector axis 12. Bath 1 is filled with molten solder 16. At the collector 12, a technological stop 17 is made to fit it closely to the cylinder 13. The supercharger 5 has a horizontal section. The magnetic circuit 4 magnetohydrodynamic pump is located on this site and the end of the magnetic circuit is made of a streamlined shape. The outer visor is cylindrical part of a replaceable jet device is located at an angle to its axis. The inlet of the supercharger 5 is made with a gradually decreasing section.
    The installation works as follows.
    The melting of the solder in the bath 1 and the knee 6 is carried out respectively by resistive heaters 2 and 7, and in the supercharger 5 - by thermal energy
    induction by single-phase magnetohydrodynamic pump. When the single-phase magnetohydrodynamic pump is turned off using a device for gripping, moving and fixing (not shown), the rotor with the collector 12 is vertically inserted into the hollow cylinder 13 of the replaceable jet device 10 to its working position. Include single-phase magnetohydrodynamic pump. The molten solder 16 is aspirated from the bottom of the bath 1, passes through the blower 5, elbow 6, confuser 14, flows out of the annular channel 15, simultaneously pours all the collector plates, enters the slots, in which the winding ends are pre-packed and the ends of the winding are soldered to the collector plates, and the excess solder is returned to bath 1. Then the single-phase magnetohydrodynamic pump is turned off, the next rotor is inserted and the cycle is repeated. When changing the diameter of the collector, the replaceable jet device is removed and inserted another one, the dimensions of the cylinder 13 correspond to the diameter of the soldering collector.
    It is recognized as an invention according to the results of the examination carried out by the Office for Invention of the People’s Republic of Bulgaria.
