Hybrid Excitation Rare Earth Permanent Magnet Synchronous Generator, (HEPMSG) which can regulate the PM generators output voltage, is a new type generator. The main part of this hybrid excited generator is the same as the permanent magnet generator, the auxiliary part is analogous to the electrical magnetic generator. Both parts share one armature and the function of the auxiliary electrical magnetic part is to regulate the HEPMSG’s output voltage with small excitation input.\;The new generator’s construction, basic principles, and the design method of the auxiliary electrical magnetic part are discussed in this paper. The mathematical model for this new generator was established,and a sample generator was developed for experimented analysis.A very promising conclusion was drawn from the above analysis and testing.
