Abstract


The concept of equivalent circuit representation including the end and edge effects of Linear induction motor (LIM) is mandatory to use in analyzing the performance of the machine. In this paper, conventional round rotor theory is extended to the analysis of LIM. The longitudinal end effect and transverse edge effect coefficients are derived which are included in the parameters that are mainly affecting the secondary resistance and the magnetizing reactance. The total primary is sectionalized to show the intensity of the effects at each section with respect to the position/movement of the secondary and developed a new equivalent circuit model. The effect of input frequency and the secondary sheet thickness on the thrust produced by LIM are analyzed. The physical interpretation for the performance degradation due to end, edge and saturation effects is made. Results have been formulated and validated with the existing literature.

Keywords: equivalent circuit parameters, linear induction motor (LIM), longitudinal end effect, transverse edge effect, thrust
