Impedance Analysis of Solid Iron Conductors

Popis výsledku v původním jazyce

Impedance analyses of a number of solid iron conductors at 400 Hz and 1000 Hz is presented in this paper. The impedance of solid nonmagnetic conductors is well documented. However, there have been fewer studies of solid magnetic conductors, because of complications caused by strong nonlinearity. Nevertheless, some industrial applications require ferromagnetic conductors, and a simple method for expressing their impedance is desirable. Solid iron conductors of various shapes are considered here. Analytical methods are developed that take into the account the eddy currents in the solid iron and its magnetic nonlinearity. Magnetization curves of solid iron conductors were measured using the yoke method and using a permeameter. The nonlinear time harmonic finite element method is used for impedance calculations of solid iron conductors. The impedance measurement results are compared with the analytical method and with finite element calculations. Hysteresis effects on resistance and inductance are also taken into consideration. The calculated results are compared with measurements at different currents and frequencies.
