Abstract

Single-sided linear induction motor (SLIM) is widely used in transportation and other field in need of linear drive for their simple, firm structure and linear motion feature without the translation mechanism. But end effect in SLIM deteriorate the performance for the discontinuous magnetic circuit. This paper analyzes 2-D transient electromagnetic field of SLIM by finite element method (FEM). The electromagnetic field-motion coupling problem was handled by the interpolation linear movement interface method. The torque was calculated by nodal force method. The variation and correlation of eddy current and electromagnetic force with respective frequency is studied in detail as well as flux density. The changing trend of longitudinal end effect in SLIM whole operation process and the influence to dynamic characteristics of SLIM is presented. The conclusions presented in this paper can give good theoretical guidance to the control and design of linear induction motor.
