Performance Comparison of Different Winding Configurations of a Novel Wound-Field Flux-Switching Linear Machine

This paper presents a study on a novel design of a Wound- Field Flux -Switching Linear Machine. Inspired by the rotating Wound-Field Switched Flux machine 18/10 topology, the concept has never been explotied in the case of a linear motor. Different armature winding configurations (double-layer and simple-layer configurations) are studied and compared with regards to open-circuit flux-linkage, force and force ripple. A non-linear Magnetic Equivalent Circuit model founded on Mesh Based Reluctance Network is developed with the purpose of addressing pre-design studies. The mesh based generated reluctance network model gives the possibility to make rapid changes in model proprieties and winding configurations. This semi-analytical model is validated using 2D Finite Element Analysis.
