Sensorless evaluation of asymmetric hysteresis loops of ferromagnetic materials / L. Cristaldi, A. Ferrero, M. Lazzaroni, A. Morando. - In: IEEE TRANSACTIONS ON INSTRUMENTATION AND MEASUREMENT. - ISSN 0018-9456. - 52:3(2003 Jun), pp. 846-851.
Abstract:
The sensorless determination of the dynamic hysteresis loop of magnetic materials, and in particular those of
magnetic plates, can be obtained under ac symmetric conditions in a relatively simple way. This paper proposes a new digital method and instrument for the sensorless evaluation of the dynamic
hysteresis loop under ac asymmetric conditions, in the presence of a dc polarization of the magnetic flux. The method is based on the determination of the parameters of a simplified linear model of the magnetic circuit, which preserve the energy equivalence. The
results of some experimental work are given in order to validate the proposed method.
