토크향상을 위한 마이크로 스테핑 모터의 구조에 관한 연구

Abstract

Recently, the PM type stepping motor preferred solution for many small electronics position determination devices since it is small in size. Thus, there are growing demands for permanent magnet(PM) type stepping motor that greater mechanical output, smaller size. This paper deals with a study of the miniaturization of the PM type stepping motor with claw-poles. We introduced the small-sized PM type stepping motor that has new structure and analyzed the magnetic characteristic of it versus general type model using 3-D finite element analysis(FEA).
