“…This pre-defined path enables the usage of flux-tubes to simplify the geometry, and therewith, enables the calculation the magnetic field. To apply the MEC modeling to more complex geometries, the modeling can be extended with the Tooth Contour Method [12] or a conformal mapping technique [13]. The extension enables the calculation of the non-arbitrary couplings between, for instance, the stator and the rotor.…”

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.

High efficiency, low cost and high reliable electrical machines are designed to meet very demanding specifications for a wide range of applications. The SynchRM (Synchronous Reluctance Motor) has very interesting properties and features. One of the main advantages is that the motor can be designed without rare earth materials permanent magnets. In this article, a modelling method of such machines using the MEC (Magnetic Equivalent Circuit) is proposed. The main challenges are to obtain a very accurate parametric model in order to calculate torque variations and to make possible geometric optimizations in future work.

“…In the hybrid analytical-numerical model the value of these parameters is given by (1), and although in (12), (13) and (15) it is possible to use values of AR g and AR M not bound to each other by (1), the fit and effectiveness of the model is still constrained by it. A model that accounts for all combinations of stator tooth width, magnet height and backiron thickness would be much more complex task resembling the development of models like those presented in [4] to [9].…”

“…The construction principle of the machine makes a performance prediction based solely on the power equation and machine dimensions not possible without the assistance of complex MEC models or FEM calculations. There are three main reasons for this: First, the double saliency of the machine makes the accurate description of the flux paths and airgap permeances a critical factor in any analysis based on MEC ([4]- [9]). Second, the nonlinear characteristic of electrical steel or any other core material used and, third, the flux concentration and partial saturation in back-iron and stator teeth make any linear approximation automatically inaccurate.…”

Flux switching permanent magnet machines are a strong contender for applications where a high torque-to-weight ratio, power density and efficiency are required. This is the case for potential future applications in aerospace propulsion where an increasing trend to investigate the feasibility of more electrical solutions can be observed. Nevertheless, its doubly salient structure and the nonlinear characteristics of ferromagnetic materials, together with the flux concentration typical of these machines make a quick and proper appraisal of this machine's capabilities or a sizing study for a specific application a nontrivial task. This paper addresses this gap and introduces a very practical and easy approach for solving this problem for FSPM machines based on the accuracy provided by input data from the finite element method (FEM), and taking advantage of the analytical simplicity of magnetic equivalent circuit (MEC) models.
