Design aspects of a high thrust density dual stator yokeless Linear Switched Reluctance Machine for harsh conditions

Abstract

This paper presents a new modular design of a yokeless Linear Switch Reluctance Machine (LSRM), the stator of which is consisted of soft ferro-magnetic segments, and the mover includes separated cores wound by a simple annular winding. The mover cores have different width while the larger one are wound by the coils, leaving the smaller one unwound. A standard design procedure is developed. 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.
