ELECTROMAGNETIC APPARATUS WITH ORTHOGONAL MAGNETIC FIELDS Russian patent published in 1997 - IPC

FIELD: electrical engineering; static energy converters. SUBSTANCE: apparatus has rectangular-section box-shaped hollow spatial magnetic core in the form of regular hollow polygon built up of sets 1 of electric steel and provided with inserts 2,3 in the form of regular hollow polygons wound of electric steel strips reducing leakage loss in joints. One magnetic core may mount two electromagnetically isolated single-phase transformers. One pair of windings 4,5 is placed inside box-shaped magnetic core and other pair of windings 6,7 is wound on box-shaped magnetic core. EFFECT: reduced size and mass, enlarged functional capabilities, reduced leakage loss. 8 dwg
