Abstract :
This paper analyzed the characteristics of the permanent magnet (PM) type claw-pole stepping motor by using 3-D finite-element analysis (FEA). As the magnetization occurs along the z-axis of the motor, it is necessary to apply 3-D FEA for analysis of the PM type claw-pole stepping motor. Considering the computation time, however, the number of the analysis model is minimized by using the "design of experiments (DOE)". By using the DOE, efficient analysis was able to be done. To see the effects of the design factors, the 3-D FEA is applied only to the selected models. As the design factors, the teeth shape, the number of turns, and the PM overhang was selected
