Abstract
The utility model relates to a large-capacity high-speed brushless excitation salient pole synchronous electric generator. The electric generator comprises a pedestal, a stator, an air-air cooling machine, and a blower. The pedestal is a steel plate welded semi-box structure. The iron core of the stator is an outer press fitting structure. The air-air cooling machine is a box type structure. The four corners of the air-air cooling machine are provided with side plates that are disposed at the upper part of the semi-box pedestal and connected to the semi-box pedestal, so that an complete pedestal is formed. The blower is disposed at the air inlet of the air-air cooling machine. The air outlet of the air-air cooling machine is provided with an air outlet cover. An adjustable door is disposed at the air inlet of the air-air cooling machine. The semi-box pedestal is only half of the conventional box type pedestal, and enables individual machining. The iron core of the stator with press fitting operation can individually carry out line inserting operation. The stator with line inserted in is integratedly immersed in a paint, so that paint immersion volume is reduced. The adjustable door is disposed between an air guiding cover of the blower and the air outlet of the blower, so that the air volume of the blower is adjusted through the adjustable door according to the output power of the electric generator, and efficiency of the blower is improved.
Description
Technical field
