International audienceThis 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
In this paper, a finite elements analysis and experimental results of a hybrid excited flux switching 3kW DCalternator are presented. The studied machine is presented and its flux control capability is calculated. The short-circuit current is explored by mean of two different methods. One of them cancels all harmonic components of the flux. The second part presents the alternator connected to a diode bridge rectifier with a DC controlled bus. The performances of the studied machine are evaluated by the model and compared to experimental results. Finally, we compared the experimental performance of the studied machine with NdFeB magnets, ferrite magnets and without magnet.
