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.

In this paper, a method to calculate the winding factor by only considering stator parameters without the rotor ones is developed. This is interesting because it allows the separation of the stator and rotor design, unlike the existing methods in the literature. A general method based on the matrix representation of a winding is presented. This approach requires the knowledge of four parameters : i) slots number, ii) phases number, iii) layers number, and iv) single-phase spatial distribution. A new feature of the multi-layer windings is introduced, it is called false-zero windings, which is divided into two categories: i) α-windings (i.e., odd false-zero windings), and ii) β-windings (i.e., even false-zero windings). The windings having no false-zero are categorized as γ-windings. The calculations are applied for single and multi-phase/-layer windings. The results of the comparison are satisfactory. The code used for the calculation is given in Appendix.

This paper presents a two-dimensional (2-D) exact subdomain technique in polar coordinates considering the iron relative permeability in 6/4 conventional switched reluctance machine (SRM) supplied by sinusoidal waveform of current. The general solutions of magnetic vector potential are obtained by applying the interfaces conditions (ICs) in both directions (i.e., r-and -edge ICs). The magnetic field is used to predict the iron core losses by using an analytical approach based on the Bertotti's model and the flux variation locus (FVL). Finally, the electromagnetic performances results have been performed and compared with the 2-D finite-element (FE) method (FEM). The comparisons with FEM show good results of the proposed approach.
