Abstract
Being exceptionally innovative, the development and research on high-speed magnetic levitation transport (MLT) has received much attention worldwide. The literature review shows an increased activity in this field in Russia over the last two decades. Regular research are conducted in Russian University of Transport, Saint-Petersburg and Rostov State Transport Universities. The status of MLT development makes it possible to employ Linear Induction Motor (LIM) for the traction of the maglev vehicles. The systems of high-speed MLT with tractive LIM use conductive bus bars as an anchor called secondary element (SE). The currents in the three-phase winding of the LIM inductor create a traveling magnetic field intersecting the SE conductive part and inducing the electromotive force (EMF), which in turn causes the flow of secondary currents. The interaction of the traveling magnetic field with the induced SE current will give rise to LIM traction. Finding the current in the LIM inductor is crucial for determining the tractive effort. The paper focuses on linear induction motor with transverse magnetic flux (LIMTMF). The conducted research was aimed at considering and solving the problem of defining the inductor current in the middle and frontal parts of the LIMTMF winding. The obtained results made it possible to increase the reliability and precision of the tractive effort calculations.
