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

摘要

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 three-dimensional (3-D) excitation flux path to control the global air gap flux. Both 3-D finite-element analysis and a comparison with experimental results are 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.
