In this paper, we propose a novel rotor structure of claw-pole motor (CPM) to reduce harmonic iron loss. In order to realize this low iron loss structure, a magnetomotive force-based a simulation method is presented to clarify the cause of harmonic iron loss. As the proposed method is based on mathematical theory, the rotor structure can be evaluated with a low computational cost. To validate its effectiveness, conventional and the proposed model are analyzed using the finite element method. The results indicate that the harmonic loss of the developed rotor is lower than that of the conventional rotor.
