Sensitivity Analysis of Geometrical Parameters on a Double-Sided Linear Switched Reluctance Motor

This paper presents a detailed sensitivity analysis ofthe effect of several geometrical parameters on the performanceof a double-sided linear switched reluctance motor (LSRM). Theanalysis was conducted in two dimensions using finite-elementmethod and takes into account only one part of the LSRM.This paper first investigates the powerful influence of stator- andtranslator-pole widths on force profiles. It then shows how theseperformance parameters are influenced by stator-pole length,translator-pole length, stack length, yoke length, and air gap. Experimentalresults confirm that the 2-D finite-element sensitivityanalysis proposed in this paper may prove to be a useful tool foroptimizing the geometry of a double-sided LSRM
