Large power generator

Abstract

The invention discloses a large power generator. The large power generator comprises a motor casing, a stator, a rotor and a main shaft, wherein the motor casing comprises a plastic outer cover, a back cover and a front cover from up to down, a fan is arranged between the front cover and the back cover, and the inner surface of the back cover is provided with heat radiation ribs projecting inwards. According to the large power generator, the inner fan inner heat radiation rib air cooling technology is employed, self temperature can be effectively controlled during large current output, a four-tube parallel structure is employed for rectification, output requirements in different rotating speed states can be satisfied, and a constant output voltage can be simultaneously realized.

Description

technical field [0001] The invention relates to the field of generators, in particular to a high-power generator. Background technique [0002] Traditional high-power passenger cars, RVs, medium and large refrigerated vehicles, and ship voltage systems generally need to be equipped with 2 to 4 generators. If a high-power generator is used to supply power to the entire vehicle, a belt drive link is omitted, which can reduce drag losses , reduce the fuel consumption of the whole vehicle by about 3%, and can be installed with only one air-conditioning bracket, but the high-power generator puts forward higher requirements for its heat dissipation, and the current passing through the generator is also relatively large. , The high current will cause great damage to the diode, resulting in a high failure rate of the generator during use. In addition, the current car air conditioner uses an air conditioner compressor, which consumes a lot of power. If a high-power generator is used...

Problems solved by technology

[0002] Traditional high-power passenger cars, RVs, medium and large refrigerated vehicles, and ship voltage systems generally need to be equipped with 2 to 4 generators. If a high-power generator is used to supply power to the entire vehicle, a belt drive link is omitted, which can reduce drag losses , reduce the fuel consumption of the whole vehicle by about 3%, and can be installed with only one air-conditioning bracket, but the high-power generator puts forward higher requirements for its heat dissipation, and the current passing through the generator is also relatively large. , the high current will cause great damage to the diode, resulting in a high failure rate of the generator during use

In addition, the current car air conditioner uses an air conditioner compressor, which consumes a lot of power. If a high-power generator is used to power the car air conditioner, it will save more power than the air conditioner compressor; and the current car needs an air conditioner in the car environment. In some cases, the car cannot be turned off, and the air conditioner will stop working once the engine is turned off. If the air conditioner can continue to work when the generator is turned off, a lot of emissions can be reduced
