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).

“…The two/three-phase excitation mode achieved a larger average torque especially in the low speed range. Taking into account the advantages of the Miller model [2], Mohsen Farshad et al [4] extended it to two-phase excitation. The model can reasonably predict the flux linkage characteristics of the two-phase excited SRM.…”

Switched reluctance motor (SRM) is becoming popular due to its simple construction, low manufacturing cost, ruggedness and fault-tolerant capability. In conventional switched reluctance motor (SRM), rotor is laminated. But in solid rotor switched reluctance motor (SRM), rotor is not laminated, and it is suitable for applications where rotors are immersed in water environment. A stationary can arrangement is introduced between stator and rotor. In this research, an 8/6 solid rotor switched reluctance motor which is used in reactivity control mechanisms of nuclear reactors is considered as test motor. As solid rotor switched reluctance motor is suitable for working in water environments in nuclear reactors, rotor position estimation is the topic of interest. A new approach which adopts two-phase excitation method is presented for rotor position estimation. Four different artificial neural networks (ANNs) with 2-5-5-1 structure are trained to estimate rotor position. The main advantage of this approach is to minimize the required number of voltage and current sensors. The validity of the new approach is verified through online comparison of estimated and actual rotor position.

“…Taking into account mutual coupling between the phases, a general nonlinear magnetic equivalent circuit model is presented in [10] for multiphase excitation of the SRM. Considering the advantages of the Miller model, they have been extended in [11] to introduce an analytical model for the SRM operating under two-phase excitation. Based on FE calculations, it is also shown that the mutual coupling between the phases has a significant influence on flux-linkage especially in high levels of phase currents.…”

In the present paper, a comprehensive electromagnetic simulation model based on finite element method (FEM) is introduced for the switched reluctance motor (SRM) by which important electromagnetic characteristics are predicted for the multiphase excitation mode. The inputs of the model are the design data and control parameters and it considers different arrangements of the phase winding connections. The simulation model is developed totally in ANSYS parametric design language (APDL) as a parametric model and it can be used easily for different types of the SRM. Carrying out 2D finite element transient analysis in the simulation model, flux density waveforms within the motor are predicted and a procedure is developed for core loss determination of the SRM operating under multiphase excitation. Applying the introduced simulation model to an 8/6 SRM, simulation results are presented for operation with simultaneous two- phase excitation.
