Design and analysis of a high-reliability flux-switching DC generator with segmental rotor

A novel high-reliability DC generator system integrating flux-switching machine with segmental rotor, of which both armature and excited windings are located in the stator, rectifier and excitation controller was proposed in this paper. At first, the working principle of SFSM and the DC generator was introduced in detail. Further, a prototype was designed based on finite element analysis of flux-switching machine with segmental rotor, analysis of working modes of the excitation main circuit topology and the closed loop control strategy. At last, a platform was built and the experiment study including static and dynamic state characteristic was conducted. The experimental result proved the design and analysis above well.
