This article considers the issue of wide implementation in various branches of the national economy caused the intensive growth of electric machines production. Due to the high specific consumption of magnetic materials in the production of electric machines, a very promising direction is the development of waste-free technology of manufacture of magnetic cores and cores by methods of powder metallurgy. The use of powder metallurgy allows reducing losses of electrical steel and eliminating many labor-intensive operations, using powder metallurgy for electrical production, it is possible to obtain sufficiently high efficiency values and reduce hysteresis losses.

The article discusses the methods of using composite magnetic alloys for elements of electrical engineering. The main methods of obtaining soft magnetic composite materials have been studied in order to obtain high-performance MMC particles, as it should be subjected to electrically insulated powder to obtain high-density parts. High densities generally improve magnetic properties, both to keep hysteresis losses low and to obtain high flux density. These give an effect when used for the cores of electric motors based on magnetically soft composite materials.
