Analysis and modeling of different topologies for linear switched reluctance motor using finite element method

In the present paper, an electromagnetic simulation model is introduced for the conventional type of linear switched reluctance motor (LSRM) in which the dynamic characteristics of the motor are predicted precisely by carrying out 2D finite element (FE) transient analysis using ANSYS FE package. The simulation model is created totally in ANSYS parametric design language (APDL) as a parametric model and it can be used easily for different designs of the conventional LSRMs. Introducing linear switched reluctance motor with segmental translator as a new type of LSRM, performance principles and design criteria are presented for two various topologies of this motor. Carrying out 2D FE transient analysis, dynamic characteristics of these two motors are predicted and compared to those obtained for the conventional LSRM.
