Design and optimization of high-speed switched reluctance motor using soft magnetic composite material

In this paper, an optimal design of a high-speed switched reluctance motor (SRM) with lower torque ripple using the Taguchi method for household appliances has been presented. To enhance the efficiency and reduce the manufacture processes of the proposed high-speed double-salient SRM, the soft magnetic composite (SMC) material is adopted. Moreover, to decrease noise and vibration of the double-salient SRM, torque ripple must be reduced; thus, the best SRM geometry should be found. To find the best geometric parameters, the Taguchi method and the finite element method (FEM) has been employed to achieve the target in this paper. The experimental results have shown that the proposed SRM can achieve the design goal for lower torque ripple and higher efficiency which is suitable for application to household electric power blenders and food processors.
