“…In simplified arc models the damping function is often assumed to be constant const S  ) (  [14][15][16]. If the static voltage-current characteristics is introduced into the formula for the dissipated power, in an analogous way as into the Mayr model, then models (23), (26) or (29) can be transformed into an equation of the following general form…”

The paper presents the Schellhase and Pentegov models utilizing static voltage-current characteristics for representing processes occurring in the electric arc. In the approximations of these characteristics variation in geometrical parameters, i.e. arc length and cross-section is taken into account. A modification of the Voronin-type models is also proposed, introducing a static voltage-current characteristic. In this way, it is possible to take into account distortions of the arc geometrical parameters of the static and dynamic character.

“…Therefore, the inductance L 11 will not depend on the frequency but only on the angle of rotation. Transforming of equations (7) and (8) and using a constant value of ν coefficient of the self inductance L 11 was determined. Using the last square method, the value of the self inductance L 11 may be determined from the relationship: In figure 10 characteristics of the self-inductance L 11 as determined from equation (14).…”

The paper deals with a mathematical model of switched reluctance motor, with stator of on induction motor. The parameters of this model were determined experimentally. The motor winding were supplied from different frequencies AC voltage source. Based on the measurements of current and voltage equivalent resistance and inductance of motor windings as a function of frequency were determined using the least squares method. The measurements for different rotation angle of the rotor were carried out. The measured resistance value was significantly higher than the value of the winding resistance because of "iron losses". The losses are modeled as the losses of a single turn wound on the rotor core, representing the eddy currents circuit. The losses are dependent on the angle of the rotor rotation relative to the stator. Based on the relationship between the equivalent inductance and resistance of the motor measured and specified of the model, the parameters were determined.Streszczenie. W pracy przedstawiano model matematyczny przełączalnego silnika reluktancyjnego wykorzystującego stojan trójfazowego silnika indukcyjnego. Parametry tego modelu określono eksperymentalnie. Uzwojenie jednej z faz silnika zasilano napięciem przemiennym o różnych częstotliwościach. Na podstawie pomiarów prądu i napięć wyznaczano zastępczą rezystancję i indukcyjność poszczególnych uzwojeń silnika wykorzystując metodę najmniejszych kwadratów dla różnych częstotliwości. Pomiary prowadzono w funkcji kąta obrotu wirnika. Otrzymana rezystancja była istotnie większa od wartości stało-prądowej rezystancji uzwojeń. Dlatego dodatkowo do modelu wprowadzono "straty w żelazie". Przedstawiono je jako straty w pojedynczym zwartym zwoju, nawiniętym na rdzeniu wirnika, reprezentującym prądy wirowe. Straty te są zależne od kąta obrotu wirnika względem stojana. Na podstawie relacji między indukcyjnością i rezystancją zastępczą silnika, zmierzoną i określoną dla przyjętego modelu wyznaczono parametry tego modelu. Przedstawiono parametry dodatkowego uzwojenia reprezentującego straty w żelazie. (Modelowanie strat w rdzeniu przełączalnego silnika reluktancyjnego).
