Abstract

The magnetic levitation technology has advantage according to flawless, high-speed and no dust, because it is non-contact. The electro dynamic suspension (EDS) is used for JR-Maglev and transportation of non-magnetic conductor. In EDS, it is important to obtain the characteristic about lift force. By the existing analysis technique, it is difficult to consider the influence of the skin effect within a conductor and electromagnetic force between gaps. The analysis that considers these is possible by the use of a three-dimensional finite element method. However, a long calculation time is needed. In this paper, the rectifying method used for the existing analysis technique is proposed. The validity is verified from examination of an experiment result and an analysis result.
