“…On the other hand, technical simulations oriented on simulation programs with integrated circuits emphasis (SPICE) [8], finite element method (FEM) [9] or method of the moments (MoM) [10] don't require sophisticated analyses of the shape of the hysteresis loops. To be useful for technological simulations, the model of the magnetic hysteresis loop should provide fast and reliable reproduction of the shape of B-H magnetization curve.…”

Recent development of SPICE, FEM and MoM software often requires the fast and reliable description of BH saturation magnetization curve. In spite of the fact that physical models of BH saturation curve are very sophisticated, for technical purposes, such curve may be modelled by simplified equations. Paper presents the quantitative assessment of the quality of four technical models of BH saturation magnetization curve performed for four modern magnetic materials: constructional corrosion resistant steel, Mn-Zn ferrite, amorphous alloy with perpendicular anisotropy as well as Finemet-type nanocrystalline magnetic material. Presented results confirm reliability of the model as well as indicate that high-speed calculation may be done using arctangent function.

“…6 shows the flux linkage vs. current relationship in the same rotor position and in the cases of sinusoidal excitation and bipolar rectangular excitation. In addition to the strong core saturation, it can clearly be seen that the flux linkage vs. current relationship is different during the rise and fall of the current due to the hysteresis of the material used in the construction of the motor [20]. Fig.7 shows the voltage and the phase current with unipolar rectangular excitation.…”

This paper analyzes the influence of excitation in the experimental determination of flux linkage vs. current vs. position relationship of a switched reluctance motor. Results of the experimental characterization of the SRM in the cases of rectangular bipolar excitation, rectangular unipolar excitation and sinusoidal excitation are compared. An equivalent model of a motor phase including magnetic flux leakage and core losses is presented and the simulation results are discussed. The component values obtained experimentally with sinusoidal excitation are maintained for both cases of rectangular excitation. The good fit between the phase current obtained experimentally and that obtained from the simulation in all three cases demonstrates the validity of the model. This enables the study of the dependence of the effects of the magnetic core on the behavior of a phase of the SRM using the same model.

“…When the diode conducts, the phase voltage is lower which can be a disadvantage for capturing this voltage if the offset of the probe has not been properly compensated, especially if this voltage has to be integrated over time to determine the flux linkage as shown in (4). Furthermore, such low voltage applied to the motor phase leads to very long demagnetization intervals.…”

This paper proposes an alternative method to obtain the experimental determination of the flux Iinkage current-position characteristics of a switched reluctance motor. Simulations are performed using different models of a phase of the motor. The results are compared with experimental measurements showing the influence of non-ideal effects associated with the magnetic core on determining the flux current-position characteristics.
