This paper presents the dynamic behavior of a Single Sided Linear Induction
Motor (SLIM) by changing many design parameters of a reference model of SLIM
then an optimization process is adopted to give the final equivalent circuit of the
proposed modified model. This analysis is prepared by using MATLAB package,
version 7.8 (R2009a) for optimization and enhancement evaluation. The
improvement in performance is performed by enhancing the efficiency power
factor product ( cos ) which can be regarded as the enhancement criteria for the
modified model of this motor. This factor improved from 0.23 of the reference
model to 0.66 of the optimized model.
