Analysis and Modeling of Acoustic Noise in the Switched Reluctance Motors with Finite Element Method

O Naderi samani, B Ganji

Abstract


Due to high importance of noise in switched reluctance motor (SRM), a coupled electromagnetic-structure simulation model is created for this motor using ANSYS finite element (FE) package. Since the main reason for producing noise and vibration in the SRM is the radial force applied to the stator pole, the radial force waveform is predicted using the 2D FE transient analysis in the developed electromagnetic model. Determination of the frequency modes and how to change the stator structure are considered in the created structure model. Applying the proposed simulation model to an 8/6 SRM, the simulation results are presented and evaluated.
