چکیده
Article history: Received: 5.1.2016. Received in revised form: 15.3.2016. Accepted: 15.3.2016. With finite element method (FEM) using ANSYS finite element (FE) package, an electromagneticstructural simulation model is introduced for the switched reluctance motor (SRM). Since the main reason of noise and vibration in the SRM is a radial force applied to stator poles, the 2D FE transient analysis is carried out in electromagnetic modeling to predict the instantaneous radial force. Based on 3D FEM, the modal analysis is done in the developed structural model to determine mode shapes and natural frequencies. Using the developed simulation model and an evolutionary algorithm, a method is proposed for design optimization of the SRM to decrease noise. To evaluate the proposed method, the simulation results are presented for an 8/6 switched reluctance motor.
