(54; THE INDUCTOR FOR THE MAGNETIZING OF NON-STANDING

MAGNETS

 one . The invention relates to electrical engineering, in particular, to devices that ensure the creation of magnetic fields of a given configuration when magnetizing the permanent magnets contained in the closed magnetic circuit of the product.

It is known a device for magnetizing a carapace type electromagnet, made with a horizontal pole axis position, pole cores, Q made of electrical steel and moved by a screw system equipped with a MANUCHNM control. Such an electromagnet allows separate permanent magnets to be magnetized.

The disadvantages of such a device are high power consumption and bulkiness, as well as the impossibility of magnetizing different pairs of permanent magnets as part of a closed magnetic circuit of the product assembly.

The closest in technical essence to the present invention is an inductor for magnetizing permanent magnets, comprising curved plates made of a material with high electrical conductivity, fixed in a dielectric block, and terminals l.

The disadvantage of this inductor is the impossibility of simultaneous magnetization of two pairs of opposite-polar magnets in the composition of the closed magnetic circuit of the product assembly, which leads to a decrease in labor productivity in the manufacture of the product, as well as to an excess cost of electricity when magnetizing the permanent magnets.

The purpose of the invention is to increase the production. efficiency and magnetization efficiency of magnets in the system.

The goal is achieved by the fact that an inductor containing curved plates made of a material with high electrical conductivity, fixed in a dielectric block, and conclusions, is made in the form of two identical U-shaped plates arranged symmetrically with a gap and facing each other by side ridge surfaces The hooks of the Igo base of the plates lie in the same SCHOSKOSGI, n jumpers, one of the jumpers located on the outer side of the bases of the U-shaped plates in their central part and on the lateral surfaces , and two other shafts connect the external face ones. the surfaces of the respective sides of the sides so that they form with the bases of the U-shaped plates a gap corresponding to the size of the magnetized magnet, while in the central part of the outer side the above two bridges are connected to the terminals. FIG. I shows the proposed inductor; Fig. 2 shows a magnetic circuit of a product with four permanent magnets that have alternating polarity. magnetization. The inductor consists of curved plates that form four rectangular avugranny angles 1. Protrusive faces 2 and 3, as well as 4 and 5 opposite pvigranyh angles are interconnected in a plane perpendicular to the direction of the magnetization axes, jumpers b and 7, which transition into conclusions: current lead 8 and current return -9, with: than jumper 6 (.7) udylen from the edge of the dihedral angle to the distance E, which corresponds to the size of the magnetisable magnet h. Other faces 10-13 d & The angles i are connected to the corresponding faces of the connected corners also by jumpers 14 and 15. The inductor works as follows. The product assembly with magnets is introduced into the working zone of the inductor. The source current, flowing through the conduit 8, passes through the curved inductor plates in such a way that it creates a magnetic field of alternating polarity in the dihedral angles, and then returns through the current output 9 to the source. In addition, the product magnets are also magnetized with alternating polarity. The polarity of the flow of current through the inductor, you can submagnetize the magnets to the desired level, not removing them from the product itself and not opening the magnetic circuit. This allows you to adjust the output parameters of the product. Compared with the prototype, an inductor allows simultaneously magnetising two opposite polar pairs of permanent magnets as part of an assembled magnetic circuit of the product, which results in a significant increase in labor productivity in the manufacture of products and energy savings. Claims of the invention An inductor for magnetizing permanent magnets, comprising bent plates made of a material with high electrical conductivity, fixed in a dielectric block, and conclusions, characterized in that, with a purpose. increasing the performance and efficiency of magnetization of the magnets in the system, it is made in the form of two identical U-shaped plates arranged symmetrically with a gap — facing the other side end surfaces so that the bases of the plates lie in one plane, and jumpers, one of the jumpers are located on the outer side of the bases of the U-shaped plates in their central part and parallel to the side surfaces, and the other two jumpers connect the outer end surfaces of the respective sides so that comfort with bases of U-shaped plates gap corresponding to the size of the magnetisable magnet, wherein the center of its outer side hour yew zotom nugye two jumper connected to the terminations.
