“…The saturation, leakage fluxes, and mutual coupling of SRMs can be modeled considering rotation of the rotor. The challenges with the existing SRM modeling techniques can be overcome by utilizing hybrid modeling techniques [88], [89], [112][113][114]. For instance, the disadvantages of Maxwell's equation-based modeling technique and FEM can be minimized by combining both techniques.…”

“…BEM has been applied in the design and optimization of SRMs [87]. The accuracy of the BEM is as high as the FEM, and it requires lower computational burden [88]. However, its major drawback is the difficulty of considering the magnetic saturation [21] due to non-symmetric and fully populated coefficient matrices.…”

“…However, its major drawback is the difficulty of considering the magnetic saturation [21] due to non-symmetric and fully populated coefficient matrices. Therefore, BEM and FEM [88], [89] or BEM and MEC [90] are commonly combined together to model SRMs. The FEM or MEC estimates the magnetic fields in the nonlinear regions whereas the BEM solves the magnetic field in the linear regions.…”

Switched Reluctance Machines (SRMs) are gaining more attention due to their simple and rugged construction, low manufacturing cost, and high-speed operation capability. An electromagnetic model of the machine is needed in the design and analysis processes. The required accuracy level of the model depends mainly on the application. A high-fidelity model is required to achieve a good design and predict the performance accurately. However, it requires high computational cost and longer simulation time. Other fast and less-comprehensive models with less computational burden could be utilized in the design and analysis of the motor drives. This paper extensively analyzes various electromagnetic modeling techniques of SRMs. Analytical, numerical, and hybrid models are considered. The paper investigates analytical models that are based on Maxwell's equations in addition to interpolation and curve fitting techniques. Numerical techniques such as Finite Element Method (FEM) and Boundary Element Method (BEM) are presented. Moreover, Magnetic Equivalent Circuit (MEC) method is discussed. Finally, potential research areas are proposed for the electromagnetic modeling of SRMs. INDEX TERMS Analytical model, boundary element method (BEM), electromagnetic modeling, finite element method (FEM), magnetic equivalent circuit (MEC) model, numerical model, switched reluctance machine (SRM).

“…BEM doesn't see significant development in electrical machine design in the last decade [14]- [16]. Reference [15] investigated the use of BEM to handle 2D magnetostatic and 3D eddy current problems, and concluded that using BEM to solve 3D eddy current problem leads to inaccurate result and the reason is due to the poor performance of the Rao-Wilton-Gilsson basis functions at low frequency.…”

The rapidly developing wind power industry demands high power generators. Direct driven permanent magnet synchronous generator (PMSG), which has the advantages of high drive train efficiency and high reliability, is promising in wind turbine applications, especially offshore. It is known, that direct driven PMSG is heavier than its geared counterparts, which increases the cost and may bring up engineering challenges. Integrating the active parts of PMSG with the blades, hub or nacelle and sharing the carrying structures can give considerable reduction of the top head mass. Integrated design challenges the electromagnetic and thermal analysis of PMSG from the perspective of whole system and the design approach may differ from the conventional. This paper presents an overview of the modeling methods for the design of PMSG. First, the drive train technology is discussed and challenges in the design of PMSG are identified. Secondly, the electromagnetic and thermal design methods are reviewed. Finally, development of simulation software is investigated.Index Terms -Direct driven, integrated design, modeling, permanent magnet generators, wind turbines.978-1-4244-8930-5/11/$26.00 ©2011 IEEE
