A novel linear switched reluctance motor : Investigation and experimental verification

Abstract

A novel stator geometry for a linear switched reluctance motor (LSRM) that improves the force profile is presented inthis paper. In the new geometry, pole shoes are affixed on the stator poles. Static characteristics for the proposed structurehave been highlighted using two dimensional (2-D) finite element analyses (FEA). A detailed sensitivity analysis of the effectof several geometrical parameters on the performance of the proposed LSRM is presented. Further, motor performance forvariable load conditions is discussed. The 2-D FEA results and the experimental results of this paper prove that LSRMs areone of the strong candidates for linear propulsion drives.
