The topology optimization of a switched reluctance motor (SRM) excited by magnetic forces is an important issue to minimize the noise and vibration level. In this paper, the magnetic force is computed using the Maxwell stress method and the optimization problem is formulated to minimize the frequency response based on the homogenization design method (HDM). The developed method is applied to the stator of an SRM to minimize the deformation caused by the magnetic harmonic excitation. Numerical simulation shows that this method successfully decrease the vibration level of an SRM.
