Figure 1 shows an electromagnet, | a general view, a section (an embodiment of implementation | for operation with two stable positions; Figure 2 is a section A-A in figure 1 in FIG. 3 an electromagnet, a general view, a section ( the variant of implementation for functioning with one stable position); in Fig. 4 and 5 the same, with the arrangement of pole pieces with the introduction of a return spring; in Fig. b - the same, with the use of a 1G-shaped shape. Electromagnet (Fig. 1) contains a coil 1 with a winding 2 wound around a coil axis 3, the fixed rm 4 covers the coil. Holds two semi-frames 4a and 4o T-shaped, which enter one another into the coil axis 3 and held together by a screw 5. The elongated holes 5a, made in one of the semi-pm, make this connection adjustable. a movable core capable of moving along the axis 3 of the coil. This core consists of a movable element that contains, on the one hand, a permanent magnet b, crackled. so that its magnetization axis 7 is perpendicular to the axis 3 of the coil, and, on the other hand, two pole tips 8 and 9, conducting magnetic flux, installed respectively from the side of each pole N and S of the magnet b perpendicular to the magnetization axis 7. Each tip 8 and 9 have two shoulders 10a and respectively On and HP,. protruding beyond the surface of the poles N and S of magnet 6. In the example described (Fig. 2, magnet 6 consists of two magnets 6a and b | with magnetization axes (7a and -7% for purely structural reasons. In the following presentation, the node of these two magnets will be denoted for convenience by the position 6. The arms of the polar parts are bent at a right angle in the direction towards the axis 3 of the coil, forming parallel ends 12 and 12S and 13a and 13b respectively. More precisely, the end 12a 121 of the pole tip 8 is located behind the ends 13a and 13W pole tip 9 with respect to the axis 7 magnetization. Thus, two localized air gap zones are formed, respectively, between parallel ends 12a-13a on one side and 12'-13b on the other. These air gap zones are located on both sides of coil 1 on both sides of the magnetization axis 7. Flat parts 14a-14b rm 4a 4b, parallel to the magnetization axis 7, are inserted into each air gap, respectively. Pole tips 8 and 9 are attached to -magnet 6 by means of plates 15, perpendicular to the axis 3 of the coils and containing tabs 16, rolled up s and pole pieces .; The guide rod D7 is connected to the movable element and is fixed along the axis 3. of the coil by supports 18 mounted on brackets 19 which are mounted on each floor 4a4b with screws. The guide rod 17 passes between the magnets ba and bb. (Fig. 2) and crosses the movable element, I will be bonded with - the latter with the help of. 20 nuts (Fig 1). The cross section of the coil 1 is essentially rectangular (Fig. 2.) and is almost filled with magnets and pole pieces. The device works as follows. When the movable element (Fig. 1) occupies its extreme lower position, the magnetic flux coming out of the permanent magnet 6 from the pole 5 side passes into the pole tip 8, shoulder 10a, bent to it, 12a and the flat part 14a of the frame 4a . From there, through the shoulders, it passes into the flat part 14 b. rma 4b, curved end 13b, polar pole 9 and plane of 5mm magnet poles Close the air gaps 12a14a and 13b and 14b create forces in the same direction that support the moving element in its lowest position. If the coil is excited in a direction that forms a magnetic flux opposite to the preceding one, then a (a procession weakens, and a pull force appears between the air gaps 13a-14a and 14b 14b, transferring the moving element to its extreme upper position. Thus, operation is ensured in two stable positions without the use of return springs and with better efficiency. To avoid shunting the air gaps 12a-14a, it is necessary ... .... to provide in the frame 4a a sufficient opening 21a around the shoulder 10a. It is also necessary to have a hole 21b for the shoulder of lOtj. These holes also facilitate assembly of the semi-rm on the coil. It is necessary to have simultaneous and complete air gaps at each extreme position in order not to significantly reduce the electromagnet performance. in the air gaps parallel to each other and the movements of the moving element are well guided and at the time of assembly of the moving element it is easy to establish identical, distances ezhdu curved ends. 12a-13a and respectively 12b-13b. For this purpose, it is sufficient to adjust the distance between the flat parts 14a and 14b rm, adjusting, for example, the connection between the semi rm. This is done with screw 5 when the electromagnet is under tension. Consider an embodiment of the invention designed to provide operation with one stable position (FIG. 3). The pole tip 9.1 contains only one lla.l shoulder, which has a curved; 13 a. 1. Parallel to the hanger of the lOb.l pole tip 8.1 added another shoulder. 1 magnetically connected to the shoulder. lOi). and having a 12c1 end bent at a right angle so that it is in a plane that the end 13 of the hanger 11 has previously defined (FIG. 1). From this, that in the upper position of the movable element, nothing changes with respect to the preceding case. In the lower position, the magnetic circuit cannot close with the pole tip 9.1, which does not have a lower shoulder, to interact with the flat part 14b.1 and to provide a magnetic connection of the parts 14a.1 and 14b.1 to the semi-pm. Under the action of the mechanical load ipi, under the action of the return spring, the movable element takes its upper position after the excitation of the coil has ceased. Thus, a functioning electromagnet occurs with one stable position. Consider the operation of the device with the input return spring (Fig. 4). The pole tip 9.2 is straight and has no curved ends, the surface in the air gaps is represented directly by the edge (or cross section) of the pins 11a, 2 and lib.2. Reducing the surface in the air gap gives a large slope depending on the stroke, which may be acceptable or necessary in some cases. . . The bent ends 12a.2 to 12b.2 of the pole tip 8.2 are bent outward with respect to the axis 3.2 of the coil. From this it follows that the forces are excited further from the axis 3.2jHo, the corresponding connection can be provided by guiding the rod 17.2. These curvatures in this direction require, from the point of view of installation, a coil frame 1.2 of two separate parts. The air gap 12a-14a (figure 1) is now replaced by an air gap. 12a.2-14a.2, flat Fate 14a, 2 half frame 4a. 2 remains at the same level as the flat part 14a (f: yg.1). In this case, the leakage of the magnetic flux between the pole tips 8.2 and 9.2 is limited and is inflamed. Installing the return spring The cylindrical compression spring 22.2 is mounted on one of the ends of the guide rod 17.2. This spring is compressed between the plate 15a, -2 and the washer 23.2, which rests on the elastic ring 24.2 inserted into the throat of the guide rod 17.2 Another elastic ring 25.2. can replace the nut 20 (Fig. 1). Bearing 18a.2 can be screwed more or less deeply into the bracket 19a.2 and behind the counter nut 26.2. The protrusion 27.2 of the support i8a; 2 serves as a fixed stop for the washer 23.2 when the latter is moved, as a result of which the beginning of the stroke can be adjusted, when the spring 22.2 applies its return pressure to the moving element. With these differences cited, the operation of the electromagnet is essentially the same as in the case shown in FIG. One of the possible options for the implementation of an electromagnet with one USSy position is shown in FIG. These arrangements are alogical arrangements / figure 3) and ensure functioning in one stable position. The bend 12a.Z of the polar part 8.3 is directed outward, and the bend 12b.Z is directed inward, as is the shoulder Yus. 3. This arrangement facilitates installation and allows the use of a monolithic coil frame. Consider a simplified version (Fig. 6) of the invention. In this embodiment, the rmo 4.4 contains only one 1G-shaped part that covers at least partially the ends of the coil 1a.4, the ends of the sides of the frame form flat parts 14a.4 and 141.4. The movable element is similar to the movable element shown in FIG. 3, with the only difference that if the pole tip 8.4 has hangers 10a.4 and 10b.4 curved in 12a.4 and 12b.4 for sides 14a.4 and 14b. 4 V-shaped frame, pole tip 9.4 straight line figure 4) and works only thanks to the edge of the hangers Na.4 And | 11b.4. The gap between the moving element and the cathode is provided to be small in order for the coil frame to serve the .T1 guide element of this element. ; . The elastic plates 28.4 of the non-magnetic material are mounted on the frame to perform the spring return relay. In this embodiment, the electromagnet operates in two stable positions. It can be made with one stable position through the modifications outlined above. The use of the Invention makes it possible to achieve a significant increase in efficiency. Thus, with a cross section of iron of 25 mm 2 and a tolgcine of a magnet of 2 mm, displacements of up to 4 mm can be obtained with a force at the end of the stroke of up to 10 N with a power of only about 1 W.
