The present work deals to investigate the performance of linear switched reluctance motor designed for a sliding door application. The objective of this paper is to develop an analytical model in order to predict the dynamic behaviour of the studied motor. Firstly, the characteristics of the proposed motor in open loop operation was computed.Secondly, the effect of the load on the response of the motor was investigated. In this context, a two technoque in open loop were adopted to solve the error positioning with load and to damp the oscillation observed in the characteristics of the motor in order to obtain a smooth motion.

Abstract-In this paper, a linear switched reluctance motor is designed and investigated to be used as a sliding door drive system. A non linear two dimensions finite model is built to predict the performance of the designed motor. Thus, the static electromagnetic characteristics are investigated and analyzed. The inductance and the electromagnetic force are determined for different translator position and current intensities with consideration of magnetic saturation effects. The results of analysis prove that the magnetic behavior of this motor is non linear. Furthermore, an important asymmetry of the static and dynamic characteristics between the extreme phases and the central phase is observed in high excitation levels.
