Abstract

The invention relates to electrical engineering, in particular to magnetic core designs and methods for their manufacture. The purpose of the invention is to provide savings for electrical steel and reduce the labor intensity of manufacturing the magnetic core. The magnetic core consists of outer cores 1 and 2 and inner core 3. The twisted layers 5 of the magnetic core of electrical steel are located on the inner side of the outer cores 1 and 2 and in the middle of the inner core 3. In the manufacture of the magnetic core, first the core is made of two parts. Two ellipsoids, wound from electrical steel, are placed in one of the parts, after which both parts are connected in some way and cut along the transverse axis of the ellipsoids. 2 s.a. f-ly, 5 ill.

The invention relates to the electrical industry, in particular to the design of magnetic conductors (Electrical apparatuses and methods for their production.

: The purpose of the invention is to save electrical steel and reduce the labor intensity of manufacturing.

FIG. 1 shows a magnetic circuit, a cross section} in FIG. On the second, top view in FIG. 3 - magnetic conductor in the manufacturing process. I The magnetic circuit of the electric apparata contains outer cores 1 and 2, inner core 3 with a circular cross section under the winding and connecting them, 4, 4. The magnetic core is made of a layer of electrical steel 5 wound in the form of ellipsoids and of layers 6 of a magnetically soft material in the form of a core. Moreover, the twisted layers 5 electrical steel located on the inner edge of the outer cores 1 and 2 and in the middle of the inner core 3

A method of manufacturing a magnetic circuit for electrical apparatus is as follows.

Layers 5 of electrical steel are wound onto a template in the form of an ellipsoid (FIG. 3) and placed into one part of the prefabricated soft material magnet 6, for example, by pressing, sintering or casting. Then, one part of the shaft 6 is trimmed with another part of the core and fastened, for example, by welding. After that, the preform of the magnetic circuit is cut into two similar parts along the section line A-A, with the section plane A-A parallel to rm 4 (Fig. 1 and 3), thus obtaining two

magnetic circuit of one electric apparatus.
