FIELD: electrical engineering.
SUBSTANCE: invention relates to electrical engineering, in particular to multiphase magnetic systems of electrical equipment. Technical result is achieved by the fact that the three-phase spatial laminated star-type magnetic core contains three identical U-shaped segments, wherein every U-shaped segment consists of sheet flat elements and features ellipse-like cross-section of the rod, each flat sheet element repeats the shape of the U-shaped segment and has dimensions described by a certain parametric dependence.
EFFECT: minimization of magnetic conductor weight.
