SPATIAL TAPE MAGNETIC CIRCUIT Russian patent published in 2021 - IPC H01F3/04 H01F27/25 

Abstract RU 2753190 C1

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering and can be used as a multiphase magnetic system for electrical equipment, the material of manufacture whereof is an electrical alloy in form of a tape. The spatial tape magnetic circuit is made by winding from a tape in form of a single continuous welded spatial structure containing an upper and a lower yokes and three rods located between said yokes at an angle of 120 degrees to each other. The rods have a circular cross-section, and the magnetic circuit winding tape has rectangular windows of variable length with a constant width and a geometric shape described by a parametric dependence. The upper and lower yokes can be made triangular in cross-section, wherein the rods are located between the corresponding corner parts of the upper and lower yokes.

EFFECT: technical result is increased efficiency and minimised weight and size parameters with maintained resource reliability during operation.
