This paper investigates the influence of various stator pole shapes and yoke structures in switched reluctance motors (SRMs) on the mechanical behavior caused by the electromagnetic force. The stator part in SRM produces most vibration. The geometric design of the stator is therefore necessary to reduce the vibration. Based on electromagnetic and structural finite element method (FEM), the free and forced vibrations for the various structures of SRM with 6/4 poles are analyzed. Then a less vibration stator structure is proposed. Some of numerical computations for a prototype motor are verified by experimental results. Index Terms-Electromagnetic force, finite element method (FEM), forced vibration, switched reluctance motor (SRM).

“…These sources are affected by the control strategy used and are characterized by complex wave patterns. The odd harmonics of these waves excite more vibrations and noise than the even harmonics [5]. It is due to this complexity that proper analytical as well as 2D/3D finite element electromagnetic and structural analysis are required.…”

“…It is due to this complexity that proper analytical as well as 2D/3D finite element electromagnetic and structural analysis are required. However, in a comparative finite element analysis of modes and frequencies of 2D and 3D SRM stator structures, it was shown that 2D finite element analysis of vibrations and noise in the stator structures is adequate, and that the error is only about 15% [5].…”

-Vibrations and acoustic noise are some of the fundamental problems in the design and exploitation of switched reluctance motors (SRM). Adequate experimental and analysis methods may help to resolve these problems. This paper presents a theoretical analysis of the magnetic force distribution in switched reluctance motors and a procedure for calculating the magnetic forces and the resulting vibrations based on the 2D finite element method. Magnetic field and force computations and a structural analysis of the stator have been carried out in order to compute the frequency spectrum of the generalized forces and displacements of the most relevant vibration modes. It is shown that for these vibration modes, the frequency spectrum can be predicted analytically.The theoretical and the numerical analyses have been applied to a 6/4 SRM and an experimental validation is presented.
