Mathematical modelling of electromagnetic forces in Linear Induction Motors

Definition of electromagnetic forces is an important stage in analysis of dynamic and static modes of linear induction motors (LIM). The report contains the mathematical model of calculation of these forces taking into account end effects and asymmetry of phase currents under different modes of LIMs. The model is characterized by decomposition of LIM into elementary motors for which the calculation is carried out on the basis of magnetic circuits' theory by taking into account the actual arrangement of phase coils along the inductor length.
