Abstract: Due to stator resistance and armature reaction, the output voltage of conventional permanent magnet synchronous generator varies with the load. However, hybrid excitation permanent magnet synchronous generator (HEPMSG), which integrates the merits of electrical excitation and permanent magnet machines, assures the output voltage keep the constant value at the variable load. In this paper, the effects of various parameters on the output characteristic of the HEPMSG were analyzed by means of resistance and reactance. The validity of method was verified by the experimental results.
