The purpose of this paper is to study the end effects in a double-sided linear switched reluctance motor (LSRM). Switched reluctance motors (SRM) and by extension their linear counterpart, LSRM, have been widely studied using two-dimensional finite element analysis (2D FEA). End effects are not included in 2D FEA, even though these effects considerably increase unaligned inductance. This paper describes a procedure that takes into account the end effects in flux linkage, inductance and force profiles on LSRM. It is based on 2D FEA corrected by the inclusion of end-winding inductance and several empirical coefficients. The results of this approach closely coincide with experimental measurements.
