Design of a double-stator linear switched reluctance motor for shunting railway channels

This paper presents the design and modeling of a double-stator linear switched reluctance motor for motorizing a railway channels shunting system. The magnetic behavior of this actuator is nonlinear due to the saturation and nonlinear magnetization curves of the materials used in this actuator. For this reason, the electromagnetic quantities such as force, flux linkage, and inductance are calculated with the finite element method using the Maxwell tool. The obtained results are presented and discussed. In order to elaborate some control strategies, a new model for the proposed actuator, based on the flux and force characteristics, is validated by the simulation results using MATLAB/Simulink.
