摘要：Linear switched reluctance machine (LSRM) offer advantages to be used in harsh conditions and low cost applications, but subject to low force density because of the nature of force production which resemble the well-known rotary SRM. A new kind of LSRM with different structure and magnetic circuit topology is presented in this paper. The presented machine incorporates a simple concentric winding and concrete ferrite-magnetic segmentations instead of the teeth type stator. Compared to teeth type linear reluctance machine, it features unique magnetic circuit and higher thrust force density. This paper analyze the principle and evaluate the performance of the presented machine. The results show that the presented linear reluctance machine gains a favorable superiority over the teeth type linear reluctance machine in terms of high force density, high reliability and low cost. The presented machine with different structural configurations are given and their performance are evaluated and discussed.
