摘要: A magnetic hysteresis model is developed based on the vector generalization of Jiles–Atherton (JA) combined with a simplified multiscale approach to take into account effect mechanical stress behavior. The aims at representing electrical steel behavior under any loading configuration considering field and second-order tensor. Mechanical introduced in JA through anhysteretic magnetization modified pinning parameter. main properties are shown alternating rotating applied induction, especially terms losses. differential susceptibility derived from model, implementation time-stepping finite-element method detailed. Finally, quasi-statically switched reluctance motor studied: different shrink-fitting conditions, resulting have significant both distribution global value
