Claw Pole Type 영구자석형 스테핑 모터의 정토크 특성 향상에 관한 연구

초록

This paper analyzed the characteristics of the claw pole PM stepping motor by using 3D FEM. As the magnetization occurs along the z-axis of the motor, it is necessary to apply 3D FEM for analysis of the claw pole PM stepping motor. Considering the computation time, reducing the number of the analysis model is effective method of the methods of the reducing analysis time. By using the “Design Of Experiments (DOE)”, efficient analysis was able to be done. To see the effects of the design factors, the 3D FEM is applied only to the selected models. As the design factors, the teeth selected models, the number of turns and the permanent magnet overhang was selected.
