Design and Characterization of a Radial Flux Wound Field and Permanent Magnet Hybrid Excitation Synchronous Machine
This paper presents the design and experimental characterization of a radial flux (RF) hybrid excitation synchronous machine (HESM) topologically realized with two coaxial rotor sections, a salient pole wound field (WF) section and an interior permanent magnet section (PM). The machine design choices are analyzed with FEA simulations to predict the behavior at no-load and at nominal load. A no-load 10:1 voltage regulation and CPSR is experimentally characterized along with a partial load dynamometer mapping.
