Journal Article 2014 03 15 Input frequency is one of the important variables in design and performance analysis of single-sided linear induction motors (SLIMs). Changing the frequency changes both the dimension of the SLIM in design process and the performance of the designed motor. The frequency influences the induced eddy currents in the secondary sheet as well as saturation level of the secondary back-iron. In this paper, the effect of the input frequency on the dimensions of the SLIM is investigated in the design process. Then, the frequency effects on the magnetic characteristics of the secondary back-iron as well as the SLIM performance are analyzed for a designed motor. Finally, the analytical results are confirmed by 2D time-stepping finite element method. https://eej.aut.ac.ir/article_90_8613985ec49eb8f757ae6439e879bb2a.pdf
