本文采用考虑涡流的棱边单元三维有限元法对直线感应电动机的推力特性进行了分析。直线电机具有结构简单、维护方便、环境污染小等优点，广泛应用于洁净室和医院的高速输送系统。然而，由于直线电机的三维形状，很难对其推力特性进行数值分析。本文采用三维有限元法计算直线电机的推力。通过计算结果与实测结果的对比，说明了三维有限元法的有效性。
This paper presents the thrust characteristics analysis of linear induction motors (LIMs) using the 3-D finite element method (3-D FEM) with edge elements taking into account eddy currents. LIMs have advantages of simple structure, easy maintenance, less environmental pollution and so on. Therefore, they are widely used for high speed transport systems in clean rooms and hospitals. However, it is difficult to analyze the thrust characteristics of LIMs numerically because of the three dimensional shape. In this paper, we calculate the thrust of a LIM using the 3-D FEM. It is clarified that the validity of the 3-D FEM by comparison of the calculated and measured results.
