Description

1 The invention relates to the electrical technology, particularly to electrical machines, and can be used to drive the mechanisms of industrial robots and manipulators, plotters and coordinator scanners, in the peripheral devices of electronic computers, as well as in two-orient feet of machine tools, presses and other industrial machines. . Known electric motor engines with measles with zvum systems are known for mutually perpendicular windings laid in grooves and an inductor made in the form of a multi-wired permanent magnet with chredukishmis on its diagonal; m poles P1 3 "The disadvantage of these engines is low accuracy movement. The closest to the technical essence is a two-coordinate direct current electric motor containing movable measles with two sia themes perpendicular to all MCiTQK located on opposite sides of a rectangular magnetic core, a fixed passive inductor from two magnetic cores located on both sides of the corromagnetic plates of the common mutual teeth systems on internal surfaces facing the respective windings, and a collector node for each coordinate, including schky in SEB rigidly associated with the anchor plate and the collector brushes; 2 j. The disadvantages of this cGL is an increased constructive slanting and control spontaneity. The aim of the invention is to simplify the engine and control it. The goal is achieved by the fact that the collector plates of each coordinate are made in the vice axially spaced washers separated. with electric strips, and the brushes are reinforced with an axial pitch equal to the winding of the crust of the core, placed on the inside of the cavity, formed by the holes of the washers, with the possibility of skapogluchik displacement, hollow non-winding with mounted on its KCiHuax bearing units and contact brushes sliding on non-coupled tokudyudom shim tires, the longitudinal axis of the xxxory coincides with ours), © the second coordinate. 84 In addition, each brush consists of several parts evenly spaced in a rashal direction along the inner perimeter of the washers. This implementation is two-coordinate. The DC motor allows to combine the functions of the guides providing movement in two coordinates and the collector node in the same structural elements, which allows to simplify the design of the motor to its control system. FIG. 1 shows the core magnetic core, common Vic; in fig. 2 — motor & tel, section along one of the coordinates; in fig. 3 - section of the collector site. with cylindrical washers; in fig. 4 is the same, rectangular shape} in FIG. 5 - motor with a detached plastic inductor, top view; in fig. b - collector unit with washers nilindr of the first form of gfi, making a multi-part brush, transverse section; in fig. 7 - the same, rectangular shape; in FIG. 8, a breakup. current carrying pins, option. The engine contains a movable part 1 (Fig. 1), made in the form of a magnetic circuit with slots 2 and 3 on the upper and lower surfaces. The width of the magnetic circuit along each coordinate is; 2pT where, TG is a pole target, VI 1, 2, 3 ... In the slots 2 and 3 there are two systems of specifically perpendicular windings 4 and 5 (Fig. 2). In the central part of the magnetic circuit of the movable element 1, a large groove 6 (Fig. 1) is made in which the excitation winding 7 (Fig. 2) is laid. The movable part 1 of the motor, n & the core windings .5 and 6 and the excitation winding 7, is placed between two parallel flat magnetic cores 8 and 9, having protrusions 10 and valleys 11 on the sides, which are filled with non-ferromagnetic material (4 1G. 2). The width of the protrusions 10 used to form the main magnetic flux is equal to c. (F) hertz of the coefficient of the calculated polar train, the total ishrina of the protrusion 10 and the depression 11 is equal to 2 the protrusions 10 correspond to (10-15) - (G, where the normal air gap of the machine Dp closes the main magnetic flux Fb and the constructive oebeoKHe or non-mobile ptsastin 8 and 9 into the monolithic design of the right-angle ferromagnet The t-racks 12, opposite the uggtak of the 8GG.9 magnetic cores (Fig., 2)., The Coppector tsvngatep consists of arbitrary-shaped tinocKHlt 13 washers, For an example, on Fm 3 and 4, cross sections of the coppectors with tsigashfichnye (Fig. 3) are attached and washers (fig. 4) washers. 13 washers were made with pivots of connecting the winding sections of the core windings and split with dielectric pads 14. In the central part of the collector washers 13 and pads 14 there are holes of arbitrary shape, determined by the technology of the collector and the brush holder. . Collector washers 13 and gaskets 14 are pressed into the body 15, which is made of an electrically insulating material. Brush holders 16 are made of ELISA material and have a broken section. On the brush holder, at distances equal to the TG of each friend of the ring, collector brushes 17 are placed, with the polarity of the brushes alternating. The conductor to the brushes 17 is made by two contact nodes, partially located on the fixed guides 18, and partly on the brush holder 16. Each contact node consists of a fixed busbar 19, having a length that ensures the complete working off of the coordinates, and contact brushes 20 sliding along it. The brush holders 16 are moved along the fixed guide 18 with the help of bearing units 21 (Fig. Aft) providing an unaccented entry of the brushes 17 into the collector and ensuring reliable contact with the collector plates. The general view of the engine from above is shown in Fig. 5. To reduce friction in the co-node, each brush 17 can be made from several parts, equally located on the inside overhead. washers 13 (FIGS. 6 and 7). This embodiment of collector evil reduces the contact surface of & jjx surfaces, increasing engine efficiency. To increase the mechanical strength of the brush holder, it can be metallic, in which case the brushes 17 are insulated from the brush holder 16 with non-conductive inserts , and the collector washers 13 are made of a TC. I am flat, rectangular in shape (fos. 8). The electric motor works as follows. When a power supply is applied to the winding of the excitation, a flow is generated in the motor that is closed at (Fig. 2U our current in the winding of 7 ifo power lines marked with a dotted line. If, using an electromechanical collector having a device describing, connect, for example, the main winding 5 to the supply mains so that the currents in its conductors have the same direction in areas where protrusions 10 are located, and in areas of cavities 11 - npoTimononoCHCHoe - the radiation, on the moving element 1, an electromagnetic force starts to act, directed to the right, parallel to the axis X. If the winding 6 is de-energized, then when the movement begins, the electromechanical collector. switches the winding sections 5 so that the direction of the electromagnetic force remains unchanged. Similarly, the root of the & hank 6 works by moving the movable element 1 parallel to the Y axis when the crustal winding 5 is not working. Reverse and stepless speed regulation is carried out in the manner customary for rotating DC machines.
