“…For example, for acoustic noise analysis, which is a major challenge in SRMs, the radial forces in the airgap and their harmonic content need to be calculated. Accurate and computationally efficient modeling techniques are required to calculate the radial forces [121], [122]. Reluctance mesh technique, ANN, and ML-based techniques can be improved to calculate the radial forces.…”

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).

“…It should be noted that radial vibration mode two is not excited in all these SRM topologies. The radial vibration modes to be excited by the electromagnetic forces depend on the number of phases and the number of stator poles [6], [8], [15]. For the 12/16 ER SRM prototype, the radial vibration modes to be excited will be discussed in Section VI.…”

“…In internal-rotor (IR) SRMs, the radial vibration of the stator back iron is often the primary source of the acoustic noise [6]- [10]. Due to the solid rotor structure of the internalrotor SRMs, the acoustic noise caused by the vibration of the rotor is often negligible.…”

Compared with internal-rotor switched reluctance motors (SRMs), external-rotor (ER) SRMs can show different vibration and acoustic noise behavior due to the differences in the designs, e.g. thinner rotor back iron to achieve smaller inertia, and longer stator pole height to improve the electromagnetic performance. This paper presents the considerations in the modeling and analysis of the acoustic noise sources of an ER SRM stator and rotor. The harmonic components of the stator tangential force density and rotor radial force density are analyzed and compared. The vibration modes, the vibration behavior, and acoustic noise of the stator and rotor are also compared. A 12/16 external-rotor SRM designed for a direct-drive E-bike application is used for the modeling, analysis, and experimental validation of vibration and acoustic noise. It is concluded that both the stator tangential vibration and the rotor radial vibration can be sources of the acoustic noise in an ER SRM.

“…The natural frequency and the modal damping ratio for each vibration mode can be obtained through analytical methods [101], FEA [102] and modal tests [103], including hammer impulse test and shaker test. Taking the 3D nodal force, mode shapes and the modal damping ratio, the vibration behavior and the acoustics of electric motors can be simulated in commercial FEA software.…”
