A Study on the Vibration Reduction of Small DC Motor
소형 DC 모터의 저진동 기술에 관한 연구
Abstract
In this paper, described is a research on the modal analysis of small dc motor by finite element method for the vibration reduction. An impact test is performed to obtain the natural frequencies and modal shapes of dc motor, which valuate the usefulness of the finite element analysis. From the study, we show that this finite element model can be applicable for designing a new motor with improvement in vibration characteristics. As an example, a new motor shape is suggested and its vibration characteristics is discussed in comparison with those of original shape.
