MAGNETIC CORE AND TRANSFORMER Russian patent published in 2021 - IPC H01F27/245 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering. The magnetic core contains a core element formed by winding the first sheets of electric steel in the form of a ring from the side of the lateral surface and has one or more curved portions visible from the lateral surface. One or more packs of second electric steel sheets are stacked together on top of each other. The stack is located on at least one of the surfaces formed by the side surfaces of the first electric steel sheets in the curved part of the core member so that the surface formed by the side surfaces of the second electric steel sheets extends along it.

EFFECT: reducing losses.
