A study on the application of finite element method to analysis of the magnetic flux distribution characteristics of the tubular motor

Tubular motor의 자속분포 특성 해석을 위한 유한요소법 적용연구

In this paper, the finite element method is applied to find the flux distribution of the magnetic field in the end region of the tubular motor. In order to analyze two-dimensional flux distribution, the r-z domain to be analyzed is subdivided into 56 nodes, 84 elements. In the case of wt=O and .pi./2, the flux distribution is shifted to the edge with frequency (w) and time (t) increase in the edge and the air gap. It is proved that this study does fit the actual phenomena.
