Abstract
Linear machines have been characterized as promising candidates for direct-drive applications such as wave energy conversion and railway traction. This is owing to the elimination of the rotary to linear mechanical interfaces which results in a very simple structure and reduced maintenance cost. In this paper, a novel partitioned stator (PS) linear wound field Vernier (LWFV) (PS-LWFV) machine is presented based on the concept of partitioned stator variable flux reluctance machine (PS-VFRM) and the magnetic gearing effect. The proposed PS-LWFV machine adopts an upper stator and a lower stator in which the armature and field windings are separately located respectively. Compared with the existing single stator LWFV machine, the proposed machine exhibits higher thrust force density and higher efficiency due to the more utilization of inner space and enlarged slot areas. The Genetic Algorithm (GA) is utilized to optimize the machine parameters for maximum thrust force based on a finite element analysis (FEA).
