Grain oriented electrical steel consists of a Silicon iron alloy with a body-centered cubic lattice. The cube edge of the crystals are the direction of the easiest magnetization and the lowest core loss. |
The concept of orienting grains in magnetically favourable direction was discovered by N.P.Goss. The corresponding texture (110), <001> is referred as Goss texture, also called Cube-on-Edge (COE) |
CRGO steels are produced under carefully controlled conditions to develop optimum magnetic properties in the rolling direction. CRGO steel develops low core loss at high induction levels when used as a core material in designs with flux path parallel to rolling direction. This contributes to low core loss in the transformers. |
