Abstract :
This paper presents improvements of Enokizono and Soda (E&S) modeling of vector magnetic properties in arbitrary direction considering alternating and rotating hysteresis of grain-oriented silicon steel sheets. Reluctivities of this modeling were calculated from measurement data obtained through two-dimensional magnetic measurement. However, the measurement was done by only 50 Hz, and the influence of the frequency was not examined fully. In this paper, we examine the frequency dependence of hysteresis curve and present an improved modeling considering frequency dependence of the eddy current
