“…where T is the period, B and Bm are the instantaneous and maximum flux densities in the considered period, ΔBi is the local amplitude of the flux density that cause minor hysteresis loss, and l is the number of the minor hysteresis loops. This approach, with slight modifications, is successfully applied in a switched reluctance motor, which exhibits extremely nonsinusoidal magnetic field variation [33]. A modified version of (9) and (10) with variable coefficients can also be used to account for additional losses in PWM inverter fed motors [34].…”

“…Usually, the iron losses are computed by FEM from the magnetic field associated to each element in the mesh. However, [11] divided the core of the motor in different parts representative points are used to fast iron loss calculation and different modified factors are applied to take into account the losses due to minor loops. The temperature impact in the iron losses under different flux densities, frequencies, and DC bias flux density are investigated by Xue et al (2017) [12], where the improved iron loss model obtained by FEM have been validated by tests on a steel lamination as well as an electrical machine.…”

In this paper, an analytical approach allowing the prediction of the iron core losses in flux-modulated permanent-magnet synchronous machines (FM-PMSMs). According to the Maxwell-Fourier method (viz., the multi-layer model) and Cauchy's product theorem, the magnetic field distribution is determined in different parts of machine by considering the iron permeability on the basis of the solving both Poisson's and Laplace's equations. Next to the direct current (DC) bias flux density and the minor hysteresis loops, which are taken into account, the Bertotti's model and the flux variation locus (FVL) are employed to calculate the iron core losses under load and no-load conditions in post-processing from the magnetic field analytical calculation. Finally, in order to validate the proposed analytical method, the results are verified by the comparison with finite-element method (FEM). The comparisons show good results of the proposed model.

“…To use the model which considers the mutual saturation effect, one should only identify the design data and the motor control parameters. In the developed simulation model, a procedure is also suggested for core loss estimation because most of available core loss models have been developed for single-phase excitation [18][19][20][21], therefore they cannot be used for accurate prediction of core loss for multiphase operation. At the following, the simulation model is described in Section 2.…”

In the present paper, a comprehensive electromagnetic simulation model based on finite element method (FEM) is introduced for the switched reluctance motor (SRM) by which important electromagnetic characteristics are predicted for the multiphase excitation mode. The inputs of the model are the design data and control parameters and it considers different arrangements of the phase winding connections. The simulation model is developed totally in ANSYS parametric design language (APDL) as a parametric model and it can be used easily for different types of the SRM. Carrying out 2D finite element transient analysis in the simulation model, flux density waveforms within the motor are predicted and a procedure is developed for core loss determination of the SRM operating under multiphase excitation. Applying the introduced simulation model to an 8/6 SRM, simulation results are presented for operation with simultaneous two- phase excitation.
