Linear induction motor has found many applications, from slow moving sliding doors to high-speed ground transportation around the world. Although various methods have been developed for the analysis of linear induction motor, only few verifiable comparisons between these methods have been done in literature. These methods solve the Maxwell’s equations in and around the geometry of the machine and take care of the physical dimensions of the machine. These methods which are proved accurate are based on Fourier transform, Fourier series and Space harmonic techniques. Out of different methods of analysis, only few methods have been reported into the literatures which are capable of taking care of topological changes in Linear induction motor. Here in this work different computer programs have been developed which are based on the above techniques. These computer programs have been validated using the published results. These have been predicting the single sided and double sided Linear induction motors. A comparison of these methods has been reported for finding their suitability for the use of these methods for predicting the characteristics of LIM under different operating conditions.
