Explicitness of Parameters Identification in Anhysteretic Curve of Magnetic Materials with Strong Perpendicular Anisotropy

Abstract

Paper presents the results of verification of the explicitness of determination of parameters for anhysteretic loop in Jiles-Atherton model of magnetic characteristics of strongly anisotropic material. For the experiments the VitroVac 6150F, cobalt-based amorphous alloy with strong perpendicular anisotropy was used. The results indicated, that anhysteretic curve very well represents the shape of magnetic hysteresis loop of such alloys. Moreover, results confirmed the explicitness of model parameters. As a result, anhysteretic curve may represent the shape of magnetic hysteresis loop during the development and optimisation of current transformers based on VitroVac 6150F amorphous alloy.
