摘要

Tubular linear switched reluctance actuator (TLSRA) with transverse flux has several advantages of simple structure, low cost and high force density, but it still suffers from relatively high force ripple that prevent it from many applications. In this paper, a novel multi-stages configuration of translator poles is proposed to reduce the force ripple of TLSRA. Based on the transversal flux distribution from finite element analysis (FEA), the original ring-shape translator pole is divided into two or three groups by considering the symmetry of radial force, and each group is shifted with certain displacement in the longitudinal direction. The thrust force distribution of TLSRA is then investigated after the force characteristic by a phase is obtained by three-dimensional FEA. Finally, the sensitivity analysis of displacement between adjacent stages on force ripple is carried out, and the reduction in force ripple factors at different displacement are presented for design optimization. Furthermore, the proposed method has no change in electromagnetic design process, and there is no additional coils or permanent magnets, which makes the method more cost effective.
