Investigation of Fe–Si–C soft magnetic amorphous ribbon samples and their potential to replace conventional crystalline Fe–Si (electrical steel) materials

Abstract The primary aim of this study is to promote the widespread adoption of Fe–Si–C-based amorphous ribbon samples and contribute to reducing power losses in energy transmission processes by offering new practical solutions. Amorphous ribbon samples with the composition Fe 92 Si 6 C 2 were prepared. The structural and magnetic properties of these materials were studied within the framework of the Random Anisotropy Model (RAM). The obtained results were compared with those of electrical steel. The high electrical resistance, favorable magnetic properties, and corrosion resistance of the amorphous samples make them advantageous for various applications. Using the methods and processing regimes outlined in this study, contactor cores were manufactured from Fe 92 Si 6 C 2 amorphous ribbons. During the experiment, the cores of a 3SC8-A122 model alternating current contactor operating at 220 V, produced by Sassin, were replaced with new cores made from the studied Fe 92 Si 6 C 2 amorphous ribbons, and industrial trials were conducted. The trials demonstrated that the application of E-cores made from amorphous ribbons enables the production of more economically advantageous contactors.
