Transverse-Flux-Type Cylindrical Linear Synchronous Motor Using Generic Armature Cores for Rotary Machinery

This paper presents the design and analysis of a transverse-flux-type cylindrical linear synchronous motor using generic armature cores for rotary machinery that can address the problem of complex structures in conventional transverse-fluxtype topologies. First, the operational principle and structural advantages of the proposed model are explained. The thrust density and cogging force are investigated during the initial design stage using an application in which large thrust density and low cogging force are required. The proposed model is both theoretically and numerically designed by using a magnetic-circuit method and a 3-D finite-element method, respectively. Finally, the results and efficacy of our structural concept are experimentally validated.
