Study and Design of the Auxiliary Part of Hybrid Excitation Rare Earth Permanent Magnet Synchronous Generator

Hybrid excitation rare earth permanent magnet synchronous generator is a new type generator, which can solve the output voltage regulation problem of the PM generator, The rotor of the generator has two parts, they are the permanent part and the electrical magnetic part, Both parts share one armature, The electrical part uses a clawliking structure, it has the same axis direction of the permanent. To regulate the magnetic field of the electrical part can regulate the output voltage. The basic principles and the design method of the auxiliary part of the hybrid excitation rare earth permanent magnet synchronous generator are discussed. It is testified by experiment that the electrical magnetic part has regulated the voltage well.
