Optimization of driving force of linear switched reluctance motor

In this paper various configurations of linear switched reluctance motor (LSRM) with permanent magnet (PM) are studied in order to obtain the high driving force construction. The 3-D Finite Element Method (FEM) is used to evaluate LSRM parameters. By comparing the maximum driving force the optimal construction has been determined. Its average driving force is increased 27%. The analysis presents that in the optimal structure the permanent magnet is applied in middle of pole surfaces.
