“…It is clearly apparent that simplified iron loss models, assuming sinusoidal variation of flux density at fundamental stator frequency, would underestimate the iron loss in the stator steel laminations. Advanced time or frequency domain methods, described in [11], must be used for accurate loss computation. It is also worth noting that at most operating points frequency of the parasitic harmonic is not multiple of the stator fundamental frequency.…”

“…In the proposed method, the d-q axis current with magnetic saturation can be determined by the modified motor model. However, the saturation effect is not considered in the conventional model; the d-q axis current is solved by Equations (1)- (4). By using park inverse transformation, the armature current can be obtained.…”

“…This core loss is a main contributing factor that decreases the power density [1,2]. Currently, core loss under the pulse width modulation control has been studied extensively [3][4][5], but relatively little has been discussed regarding core loss under SVPWM excitation. In particular, different control systems play different roles in core loss [6].…”

Abstract:Core loss is one of the significant factors affecting the high power density of permanent magnet machines; thus, it is necessary to consider core loss in machine design. This paper presents a novel method for calculating the core loss of permanent magnet synchronous machines under space vector pulse width modulation (SVPWM) excitation, taking magnetic saturation and cross coupling into account. In order to accurately obtain the direct and quadrature (d-q) axis, current in the given load condition, the permanent magnet motor model under SVPWM excitation has been modified, so as to consider the influence of magnetic saturation and cross coupling effects on the d-q axis flux-linkage. Based on the magnetic field distribution caused by permanent magnet and armature reactions, the stator core loss can be calculated with the core loss analytical model, corresponding to the rotational magnetic field. In this study, the method has been applied to analyze core loss in an interior permanent magnet synchronous machine, and has been validated by the experimental results. The influence of pole/slot number combinations on core loss in the same on-load condition is also investigated. This study provides a potential method to guide motor design optimization.

“…The effect of rotor lamination material on total core losses has been studied through measuring and simulating the machine with three prototype rotors [17]. In another valuable work, a comparison of frequency and time domain iron and magnet loss has been presented, where the focus is on recognizing the significance of including the analysis of higher harmonics in the electromagnetic loss calculation [18].…”

The paper presents an advanced quasi-FEA technique on the iron losses prediction using Bertotti's iron loss separation models, in which a curve fitting is taken into account for coefficients calculation of each model. Moreover, the skin effect and saturation consideration are applied in order to check the accuracy through the relative error distribution in the frequency domain of each model from low up to high frequencies 50 to 700 (Hz). Additionally, this comparative study presents a torquespeed-flux density computation that is discussed and presented. The iron loss characteristics of a radial flux permanent magnet synchronous machine (PMSM) with closed-slots and outer rotor topology are also discussed. The quasi-finite-element (FE) analysis was performed using a 2-D and 3-D FEA, where the employed quasi-2-D FEA is proposed and compared with 3-D FEA, and along with experimental verifications. Finally, all the iron-loss models under realistic and non-ideal magnetization conditions are verified experimentally on a surface-mounted PMSG for wind generation application.
