Behaviour of electrical steels under rotational magnetization and high temperatures
Résumé
Rotational characterization on samples of electrical steels (FeSi GO and NO) are made for temperatures between 50°C and 200°C. The losses decrease with temperature as dictated by the theory, as does the observed anisotropy; quantitative data of both phenomena are shown. In addition, the necessary magnetic field to reach the same circular flux density raises considerably with heat
