EFFICIENCY OF LOCAL DEFORMATION EFFECTS ON THE MAGNETIC STRUCTURE OF CORE ELEMENTS

DOI: 10.17804/2410-9908.2018.6.165-172

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%.

Acknowledgments: The work was performed within the state assignment on the subjects of Magnet (No. AAAA-A18-118020290129-5) and Diagnostics (No. AAAA-A18-118020690196-3) and supported by UB RAS project No. 18-10-2-8.

Keywords: transformer steels, stacked core, structure, domains, scribing, thermomagnetic treatment, core losses
