Abstract

Mathematical models for reconstruction of the principal magnetization curve of sheet electrical steel from the measured weber-ampere characteristic are designed. Samples of steel 3408 taken by parallel shears and by laser cutting are studied with the help of a device for rapid control of magnetic characteristics of sheet electrical steels. The error of the determination of the magnetization curve with the use of the models does not exceed ± 5%. The results obtained make it possible to raise the efficiency of monitoring of magnetic properties of sheet steels under the conditions of large-scale production of magnetic cores of electrical devices.
