Abstract

This paper presents a new non-iterative method for the determination of the equivalent circuit parameters of single–sided linear induction motors. In the proposed method, the relative permeability of the back iron is calculated by a simple function. Then using electromagnetic analysis, the parameters of the equivalent circuit are obtained. Next, a few approximations are proposed to develop an individual expression for calculation of each of the equivalent circuit parameters. The obtained expressions show the relation between the parameters and different features of motors such as pole pitch, input current, and slip
