Production of Plate Magnet Cores in Modern Transformers

The article considers two constructions of modern magnet cores – plate cores made of electrical steel and twisted cores made of amorphous steel. The production technologies of magnet cores with straight plate joints, oblique joints (at an angle of 45°) and on the “Step-lap” configuration are considered. The production process of a magnetic core without upper yoke is detailed. The features of the amorphous steel magnetic core assembly are given.
