Abstract

To reduce the vibration of a switched reluctance motor (SRM) with an amorphous alloy core, a topology optimization technology for the stator core of SRM based on the addition of negative magnetostrictive material is proposed. Firstly, the teeth of the stator of SRM are selected as the optimization regions that contain negative magnetostrictive material. Utilizing the Solid Isotropic with Material Penalization (SIMP) model, the interpolation function of the material density is used to characterize Young’s modulus and relative permeability in the optimization regions. Secondly, the magnetic-mechanical coupling topology optimization of the SRM is performed. With the elastic strain energy and static torque as constraints, and the minimization of vibration displacement as the optimization objective, the optimized lower vibration topology for a stator core filled with negative magnetostrictive material is carried out. Finally, the effectiveness of the optimized lower vibration topology is verified by simulation and experimental results. The results show that the vibration displacement of the stator of the SRM core is reduced by 21% after topology optimization.
