Метод определения параметров петли гистерезиса по экспериментальным данным

Abstract

A method of approximation of hysteretic loop in an electromagnet ferromagnetic core is proposed based on representation the loop as the sum of a magnetization curve and ellipsoidal closed curve. Rations for coefficients of Fourier decomposition of the reserved curve are offered. The method allows increasing exactness of approximation of the loop at designing of an electromagnet with ferromagnetic core.
