Abstract:
A deeper understanding of materials characterization under rotational magnetization conditions phenomena enables the engineers to optimize the overall volume, mass and performance of devices of electrical machines in industry. These directions can be obtained through destructives tests as the Epstein frame method and the Single Sheet Tester (SST) measurements in the irreversible domains region of the magnetization. At the present work, a proposed system is applied to the experimental evaluation of magnetic anisotropy in steels. The proposed approach is considered nondestructive and showed to be able to determine the easy directions. Samples of rolled SAF 2205 steel are submitted to an induced magnetic field in the reversibility region of magnetic domains, to detect the easy magnetic direction. These magnetic fields were applied to circular samples which have different thickness and the application angle varied from 0° to 360° with step of 45.
