Numerical and experimental analysis of equivalent magnetostriction forces in grain-oriented electrical steel
Source abstract
Abstract
This work investigates the vibratory behavior of single-phase magnetic cores made of grain-oriented electrical steel (GOES) through numerical and experimental approaches, focusing on magnetostrictive effects. A controlled non-shifted core configuration is studied. It prevents the magnetic flux circulation between sheets, ensuring deformations are solely attributed to magnetostriction. Modal analysis, finite element modeling, and an inverse force identification method are employed to determine equivalent magnetostrictive forces with validation through experimental measurements.
