Abstract Hybrid excitation synchronous generator has two magnetic sources: Permanent magnets and exciting windings. A novel tangential/radial hybrid excitation synchronous generator (T/R-HESG) is studied in this paper. The relationship of fluxes produced by permanent magnets and exciting windings is studied. The flux of air gap in HESG can be controlled. Meanwhile, the parameters of structure are analyzed for optimization. A novel brushless method is designed, because the characteristic of T/R-HESG. Comparing with traditional brushless scheme. The problems such as complex system and long axial length can be overcome by novel method. Also, the problem of excitation of starter can also solved by this method. The design of exciter is special. The method of exciter design is studied. The model of the system is built. The influence of commutation overlap angle is studied. Two operation model of rotating rectifier are anylzed. A prototype is made to do experiment. The experimental studies of generation system are to verify the correctness of design. The process and design can be referred to for the design of brushless generation system.
