Özet

Air gap flux of Hybrid Excitation Synchronous Machine (HESM) is provided by a combination of permanent magnet and excitation winding MMFs. Thus flux weakening or flux boosting can easily be achieved. HESM can be series or parallel double excited. Many models have been proposed for radial flux HESM structure in literature. However, axial flux machines have some characteristics such as high efficiency, high power/torque density, low noise and vibration. In this study, a novel Axial Flux Hybrid Excitation Synchronous Machine (AFHESM) with magnetic bridge is proposed. The structure and operation principle of the AFHESM are described. No-load and load operation of a 3D generator mode is investigated by Finite Element Method.
