Investigation of a New Topology of Hybrid-Excited Flux-Switching Machine with Static Global Winding: Experiments and Modeling

This paper presents a new structure for a hybrid excitation, flux-switching synchronous machine. The particularity of this machine is its global excitation winding component that creates a 3D excitation flux path to control the global air gap flux. A 3D finite element analysis and a comparison with experimental results are both provided. This model makes it possible to: show the excitation flux path, explore the flux-regulation capability of a new structure, and identify the influence of material characteristics. The experimental performance of this machine in a DC generator is presented and compared with simulation output.
