  A field-winding type claw-pole motor has a three-dimensional complicated structure. In addition, its characteristics depend on not only an armature current but also a field-current. Therefore, to estimate the characteristics of the field-winding type claw-pole motor, three-dimensional electromagnetic field analysis combined with its drive circuit is required. In a previous paper, three-dimensional relcutance network anaysis (RNA) model of the claw-pole motor was proposed and the validity of the proposed model is proved by comparing with the results of torque characteristics obtained from finite element method (FEM). This paper presents a method for calculating eddy current loss on the rotor surface of the claw-pole motor based on RNA.
