“…For decades, the saturation effect can be overcame by using a nonlinear MEC. In this type of modeling, we notice that the iron losses are estimated with the aid of models such as Steinmetz [33][34][35][36][37][38], Bertotti [39][40][41][42][43] and others [44], established for the magnetic material constituting the device. Nowadays, there are no bibliographic data available in the literature dealing with the evaluation of the iron losses by using a precise hysteresis model based on the magnetic flux density waveforms resulting from a MEC.…”

Abstract:In this paper, an original approach allowing the determination of the iron losses in the electromagnetic devices is presented. This new approach exploits the Loss Surface (LS) hysteresis model and the magnetic flux density waveforms resulting from a generalized nonlinear adaptive magnetic equivalent circuit (MEC) using a mesh-based formulation in two-dimensional (2-D) or quasi three-dimensional (3-D). The model coupling has been applied to a 18-slots/16-poles radial-flux interior permanent-magnet (PM) synchronous machine (PMSM) dedicated to automotive applications, mainly for electric/hybrid/fuel cell vehicles (EVs/HEVs/FCVs). The obtained results have been compared with those made retrospectively in the 2-D transient finite-element (FE) Flux TM . The influence of the MEC discretization on the iron loss calculation and the electromagnetic performances has been analyzed. The computation time is divided by 3/2 with an error less than 7 %.

“…The Fourier modeling is extensively discussed by Gysen [9], while the mesh-based MEC modeling is known from [18][19][20]. The combination of a mesh-based MEC modeling with harmonic modeling methods is proposed in [21][22][23][24]. Where Ouagued [21], Barakat [22] and Laoubi [23] only connect the mesh-based modeling to the harmonic modeling on one side, this paper applies a bidirectional coupling on both sides of the MEC-region.…”

Hybrid Analytical Modeling: Fourier Modeling Combined With Mesh-Based Magnetic Equivalent Circuits

2015

View full text Add to dashboard Cite

This paper presents a hybrid analytical modeling method which integrates a mesh-based magnetic equivalent circuit model with the Fourier modeling approach. This hybrid analytical modeling is capable of correctly predicting the electromagnetic field distributions for various two-dimensional geometries. The generalized approach of the presented hybrid modeling concept, makes the modeling technique applicable to a wide range of electromagnetic devices. By only meshing the parts of the domain in the vicinity of the high permeable materials, the increase in computational effort is limited compared to the sole use of Fourier modeling. The proposed hybrid analytical modeling method predicts the force in the geometry with ≥ 97 [%] accuracy with respect to finite element analysis.

“…Hybrid models (the local/global saturation): The analytical solution can be combined with numerical methods [54][55][56][57] or (non)linear MEC [58][59][60][61][62][63][64][65][66][67]. Usually, the analytical solution is established in uniform regions of very low permeability (e.g., air-gap, and magnets) and other methods are sought in regions where magnetic saturation cannot be neglected (i.e., the stator and/or rotor iron cores).…”

Abstract:The most significant assumptions in the subdomain technique (i.e., based on the formal resolution of Maxwell's equations applied in subdomain) is defined by: The iron parts (i.e., the teeth and the back-iron are considered to be infinitely permeable, i.e., µ iron → +∞, so that the saturation effect is neglected. In this paper, the authors present a new scientific contribution on improving of this method in two-dimensional (2-D) and in Cartesian coordinates by focusing on the consideration of iron. The subdomains connection is carried out in the two directions (i.e., x-and y-edges). For example, the improvement was performed by solving magnetostatic Maxwell's equations for an air-or iron-cored coil supplied by a direct current. To evaluate the efficacy of the proposed technique, the magnetic flux density distributions have been compared with those obtained by the 2-D finite-element analysis (FEA). The semi-analytical results are in quite satisfying agreement with those obtained by the 2-D FEA, considering both amplitude and waveform.
