Domain structure and magnetic losses in laminated magnetic circuits upon laser treatment


Methods of optimizing the magnetic domain structure and functional characteristics of electrical-sheet anisotropic steel based on the Fe-Si alloy and the laminated magnetic circuits of transformers have been developed. The use of an efficient complex based on the local laser treatment and application of magnetically active electrically insulating coatings provided a significant reduction in the magnetic losses in the sheets of the steel (by 18–22%) and in the magnetic circuits of transformers (by 9–14%).
