This paper deals with a novel design method for low torque ripple and voltage ripple of interior permanent-magnet synchronous motors (IPMSM s) by using ferrite shells on the rotor surface. The IPMSM with ferrite shells is optimally designed with two design variables related to th e structure of the ferrite shells by using the response surface method and the finite-element method in order to minimize torque ripple and voltage ripple. In the vicinity of air gap of the IPMSM, the magneti c flux remarkably fluctuates due to flux-weakening control by the vect or inverter. Ferrite shells on the rotor surface can decrease the fluctuation of the magnetic flux effectively. For this reason, the proposed method is a good solution for the robust control of I PMSMs.
