Improving the Energy Efficiency of Electric Machines For Specialized Railway Rolling Stock

Switched reluctance motors (SRM) are increasingly used in various industries and vehicles. It is of interest to use SRM alternately in the generator and engine modes to perform various functions in vehicles. The article presents the results of research on improving the energy efficiency of SRM, which is used not only for generating electricity during the route, but also for moving to the place of loading or unloading of specialized railway rolling stock. An algorithm for determining the optimal control actions of SRM is proposed, which allows to significantly reduce the electrical losses in the winding. The calculated data on the parameters of the SRM operation in the optimal mode are presented. The optimal control problem was solved using the maximum principle. The initial conditions for auxiliary functions were determined by the Newton-Raphson method.
