Abstract

Due to the special design of the segmental translator linear switched reluctance motor (STLSRM), it has a higher power density than conventional linear switched reluctance motor (LSRM). Having enough information about the parameters affecting the motor output can help to improve its performance. In this paper, a step-by-step and integrated method is presented for the standard design of STLSRM. After obtaining the design equations, the important and effective parameters on the STLSRM performance are determined and discussed. Using sensitivity analysis, design considerations and comprehensive instructions are provided to determine the STLSRM dimensions. In order to confirm the design process, a typical STLSRM is designed for the use of electric sliding doors, and with the goal of increasing the average instantaneous thrust force and reducing the force ripple, based on the design of experiments (DOE) approach and the response surface method (RSM), the optimization of STLSRM is done. In order to validate, using the finite element method (FEM), the performance characteristics of the optimized STLSRM including flux-linkage, co-energy, static force, instantaneous thrust force waveform and instantaneous current waveform are compared with those of derived from the initial design.
