Abstract
Linear switched reluctance motor (LSRM) has proven its suitability in transit applications due to the advantages of direct drive, low cost and simple mechanical structure. In evolution of LSRM, its force performance is the prime concern for the manufacturers. This factor is mainly governed by its physical design. Force characteristics are quite important for obtaining precise design of the LSRM. Because of its nonlinear characteristics, quantitative measurement method for measuring various parameters of the LSRM has not been generalized. This paper discusses finite element analysis-based design considerations for measuring various performance parameters of the LSRM. The paper incorporates the design studies of the LSRM as per analytical expressions and validated using finite element method (FEM)-based ANSYS/Maxwell software. Finite element analysis includes measurement of force, flux and inductance characteristics of the LSRM. Further, it optimizes the motor parameters for maximizing the thrust force of the motor. The proposed study is crucial in estimating various performance parameters of the LSRM using FEM and propagating the traceability chain in parameter estimation of LSRM using three-dimensional FEM-based model of the motor.
