Abstract

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