A Novel Linear Switched Reluctance Machine: Analysis and Experimental Verification

Abstract

The important problems to be solved in Linear Switched Reluctance Machines (LSRMs) are: (1) to design the shape and size of poles in stator and translator cores; (2) to optimize their geometrical configuration. A novel stator geometry for LSRMs that improved the force profile was presented in this study. In the new geometry, pole shoes were affixed on the stator poles. Static and dynamic characteristics for the proposed structure had been highlighted using Two Dimensional (2-D) Finite Element Analyses (FEA). Motor performance for variable load conditions was discussed. The finite element analyses and the experimental results of this study proved that, LSRMs were one of the strong candidates for linear propulsion drives.
