Efficiency of Local Deformation Effects on the Magnetic Structure of Core Elements

摘要

Prospects for optimizing the domain structure and reducing specific magnetic losses in Fe-Si (110) – elements of multilayer laminated transformer magnetic cores – are considered. The formation of local deformation zones by mechanical scribing decreases the domain size and the eddy-current component of magnetic losses; it directs the magnetic flux in the linear and angular portions of the magnetic cores along the easy axes. The established optimal processing conditions and the subsequent annealing in a magnetic field reduce specific magnetic losses in the magnetic cores by 10-12%.
