Abstract

In this paper, a ladder linear induction machine is modelled in five subdomains to extract the performance parameters of the machine with high accuracy. The rotor slots, rotor slot opening, airgap, stator slot opening, and the stator slots are five investigated subdomains in this analytical model. The magnetic vector potentials (MVPs) of each region are obtained by solving the Maxwell equations in each subdomain. The continuity of the magnetic flux density and Ampere's law are the applied boundary conditions to find the MVPs. The inductances of the electric equivalent circuit (EEC), including leakage and magnetizing inductances, are obtained from the MVPs. A method for prediction of the saturation level in the iron parts using SDM model is proposed. It estimates the saturation level by consideration of an ampere loop at no-load condition. The EEC is used to predict the performance of the machine. The accuracy of the model is validated via 2D finite element analysis. The results demonstrate the reliability and accuracy of the developed model in the performance prediction of the ladder linear induction motor.
