Abstract:
The aim of this paper is to present a research of magnetic hysteresis loops
of a toroidal ferromagnetic core made of electrical steel. The experimental
results of induced voltage, magnetic induction and hysteresis loop obtained
at different frequencies of the sinusoidal excitation magnetic field have
been presented. The harmonic content of the induced voltage and magnetic
induction have been calculated using Fast Fourier Transformation. Observed
variation of higher harmonics with frequency has been correlated to the
mechanism of magnetic domain walls damping. A variation of harmonics of the
magnetic induction with the amplitude of the excitation magnetic field has
been analysed and a proper mathematical model has been proposed. Furthermore,
the influence of the triangularly shaped excitation magnetic field and the
distorted shape excitation that produces sinusoidal induction on the shape of
hysteresis loop and harmonic content of the induced voltage and the magnetic
induction has been analysed and discussed.
