This paper presents a biased flux hybrid-excited flux switching (BFHEFS) machine to improve the flux adjustability. The proposed configuration adopts E-core to enhance the permanent magnet (PM) material utilization ratio, which use half PMs of the conventional flux switching PM (FSPM) machine. The flux-adjusted principle of the E-core BFHEFS machine is introduced to explain the better flux adjustability...
In general, the brushless wound rotor hybrid excitation synchronous generator (HESG) needs a separate exciter. In this paper, a novel integrated brushless excitation HESG (IBE HESG) is developed by integrating the excitation section into the iron core of wound rotor HESG. Compared with the conventional brushless excitation method, the axial length of the IBE HESG is shorter and the original topology...
A novel hybrid excitation synchronous generator (HESG) with tangential/radial magnetic path in parallel connection is proposed in this paper. The HESG combines the merits of permanent magnet synchronous generators and electric excitation synchronous generators. The structure characteristics of the HESG are described and the operation principle is introduced. The basic characteristics of the HESG are...
