The invention relates to electrical engineering, in particular to magnetic systems on permanent magnates, and can be widely used in load handling devices and magnetic plates,

The purpose of the invention is to increase the power of gi.

FIG. 1 shows a schematic design of a magnetic system: FIG. 2-5 shows the elementary magnetic systems of one of the units.

The magnetic system contains fixed and movable blocks arranged one above the other, made in the form of a series of elementary systems fastened together, containing a permanent magnet and a magnetic core made of two parts, one of the blocks having one more elementary system

The outer part of the magnetic circuit of the elementary system of the upper block is made in the form of a rectangular cup 1 in which a magnet is placed, also made in the form of a solid cup 2 of a rectangular shape, the inner surface of which includes the lateral surface and the bottom surface has one polarity and the outer surface , which also includes the side surface and the bottom surface - the opposite polarity, the second part of the magnetic core is placed inside the magnet cup 2, for example in the form of a rectangular rod 3, and tsovye magnetic part and a magnet provided on one level of the upper block adjacent elementary systems are separated from each other plates 4 of a non-ferromagnetic material and their glasses magnets have opposite polarity on the same surfaces.

The elementary systems of the lower block are made as a continuation of the elementary systems of the upper block. In this case, one part of the magnetic circuit of the elementary system of the lower block is made in the form of a rectangular cup 5 without a bottom, the magnet 6 is also made in the shape of a rectangular cup without a bottom and is magnetized perpendicular to the walls, and the rod 7 has the same shape and section as the core 3. The magnetic system is in the Enabled state, in which the product 8 can be captured by it in the load gripping device.

In the absence of technological equipment for continuous magnets 2 and 6 of a complex shape, they can be made of individual magnetic tiles, positioning them as shown in Fig.2-5

In figure 2, the magnetic tiles 10 and 11 are equal in length to the depth of the glass of the magnetic circuit. Magnetic plate 9 is located between the tiles 10 and 11.

In fig.Z the length of the tiles 10 and 11 is equal to

the length of the rod 3, and the entire space above the tiles 10 and 11 and the rod 3 is occupied by tile 9.

4, the magnetic tiles are made

with beveled edges in contact at an angle of approximately 45 °

In Fig. 5, the magnetic tiles 10 and 11 have areas of poles equal to the surfaces of the rod 3 with which they come into contact,

5 The remaining space 12 may be filled with adhesives.

The magnetic system works as follows.

In the initial position, the system is installed on the part 8 and is in the position shown in Fig. 1 (the On state). In this position, the magnets of each elementary magnetic system of the upper block are connected to a parallel

5 tons with magnets of elementary systems of the lower unit and magnetic flux lines of both units are closed through part 8. Under the action of a magnetic field, part 8 is attracted to the system.

The role of the non-ferromagnetic plates 4 is reduced to the separation of the elementary systems in each block from each other in order to more evenly distribute the magnetic flux through the parts of the magnetic circuit in each elementary system. Otherwise, in the absence of plates 4, the adjacent magnetic systems in both blocks will have an adjacent wall, in which, due to the action of the adjacent magnets, there will be no

0 magnetic flux directed to the part 8. At the same time there will be an increase in magnetic fluxes through the rods 3 and 7, which is undesirable because it can lead to saturation. Thus, in the absence of

5 plates 4, the total end surface of the magnetic cores, transferring the magnetic flux of the part 8, will decrease.

To release part 8, the upper block should be shifted to the right by the width

0 one elementary system. In this case, the magnets of the upper and lower elementary systems, located one above the other, are turned on with respect to each other, their magnetic flux

5 closes, as in the known magnetic systems, inside the system, and the item 8 is released (the state is turned off).

The proposed magnetic system differs from the known ones in that it allows to direct almost the entire magnetic flux into one

side and thereby increase the power of ti gi. It allows the fragile microns to be surrounded by ferromagnetic armor, to increase the bone and strength of the blocks of the system, to make it necessary to use magnetic plates of a non-ferromagnetic body.
