Abstract
The utility model relates to a large capacity high-speed brushless salient pole synchronous generator which comprises a generator rotor, a generator base, a generator stator and a shield with a cooler. The generator rotor is a salient pole synchronous generator rotor. The generator base is in a steel plate weld box-shaped structure. The generator rotor is supported by an end cover type bearings. The end cover type bearings support both ends of the generator base. The upper plane of the generator base and the axis central line of the generator are at the same level. A stator iron core with a winding and the base are fixed together. The shield with the cooler is arranged above the generator base and forms a cavity with the generator base. The generator rotor and the generator stator are wrapped in the cavity. Due to the fact that the generator rotor uses a salient pole structure, the generator has the advantages of simple structure and short manufacturing production cycle. Due to the fact that the generator base uses the box type structure, the generator has the advantages of simple and reliable structure and light quality. The generator stator undergoes line inserting and then is placed into the generator base, thus the operation is simple.
