Abstract
The present invention discloses double air-cooled IP54 generators inside and outside one kind, and traditional IP54 generators are " generator+cooler bin " combining forms, and the present invention uses flange-cooled pig machine base, by two fan coolings inside and outside generator itself, forms double air-cooled structures.To help to radiate, following adjustment is done to punching shape：One, stator punching outer circle is evenly distributed with several grooves, allows hot inside air to be contacted with engine base wall by these grooves, reaches heat exchange；Two, rotor interpolar supports the rotor windings of close yoke with stainless steel strut using triangular shaft to ventilating duct, increases the volume that internal rotor transmits hot-air.There is the generator good characteristic continually and steadily run under various complex environments can be polluted with effective noise reduction function also as its degree of protection is high.The present invention is at low cost, small, light-weight compared with 54 similar product of Traditional IP, is more widely applied.
Description
Technical field
The present invention relates to a kind of generators, double air-cooled IP54 generators especially inside and outside one kind.
Background technology
Open generator is susceptible to overstocked or internal humidity of internal particle object etc. in use because closure is poor
Problem causes the damage of generator.And traditional closed generator, because it mostly uses " generator+water cooler " combining form,
Volume is big, of high cost.Generator of the present invention has outstanding environmental-protecting performance, compares open generator, is released in addition to being substantially reduced
Outside the noise put, because its degree of protection reaches IP54, moreover it is possible to prevent harmful dust accumulation, prevent all directions from splashing
Water is invaded, and is effectively reduced the injury that motor is subject to, is extended the service life of generator, reduce the waste of raw material.Even with
The similar IP54 generators of tradition are compared, and the present invention also has 3 advantages：It is at low cost, small, light-weight, so using more wide
It is general.
Invention content
The purpose of the present invention is to provide double air-cooled IP54 generators inside and outside one kind, have a wide range of application, have various
The good characteristic continually and steadily run under complex environment.
The present invention is achieved like this：Double air-cooled IP54 generators inside and outside one kind, include mainly drive end bearing bracket, forefan,
The fan housing of stator, rotor, engine base, exciter stator, exciter rotor, rear end cap, external fan and fuselage afterbody；Its feature exists
In：The engine base of generator is the ironcasting with radiating ribs, is assembled with front and rear cover, is aided with deep-groove ball axis of the both ends with sealing ring
It holds, forms a closed structure, stator, rotor, exciter, forefan can be wrapped in inside.Forefan, which is mounted on, to be turned
Between son and drive end bearing bracket, rear fan is mounted on the outside of rear end cap, is placed in the fan housing of fuselage afterbody.The type of cooling is inside and outside double
It is air-cooled：Forefan stirs the heat that rotor, stator, exciter generate, and is allowed to distribute to motor by heat exchange along engine base wall
Outside, rear fan cooperation are wrapped in the fan housing on back body, axial ventilation road are formed, to rear end cap surface and engine base surface
Cool down.
Using flange-cooled pig machine base, surface radiating piece is seen linearly along short transverse.
Take the structure for setting cooler on conventional engine base different from traditional IP54 generators, patent of the present invention using
Flange-cooled pig machine base radiates by inside and outside double air-cooled structures.
Internal fan stirs the heat that rotor, stator, exciter generate, and is allowed to exhale along engine base wall, then by outer
Fan blows away the heat on engine base outer surface and its cooling fin.
Stator punching is full wafer punching, if being evenly distributed with groove in punching outer circle, when stator punching outer circle is close to inboard wall of base,
These grooves can play the role of ventilation slot.
The rotor windings that close yoke is supported with stainless steel strut, under the premise of ensureing that magnetic line of force transmission area is enough,
Silicon steel sheet is reduced as far as possible in the area of curvature, so can reach the effect for increasing air duct.
Description of the drawings
Fig. 1 is the electric generator structure figure of the present invention；
Fig. 2 is the stator punching figure of the present invention；
Fig. 3 is the rotor punching figure of the present invention；
Drive end bearing bracket 1 in the figure, forefan 2, stator 3, rotor 4, engine base 5, exciter stator 6, exciter rotor 7, rear end cap 8,
External fan 9, the fan housing 10 of fuselage afterbody.
Specific implementation mode
The present invention is implemented, double air-cooled IP54 generators inside and outside one kind, includes mainly drive end bearing bracket 1, forefan 2,
Stator 3, rotor 4, engine base 5, exciter stator 6, exciter rotor 7, rear end cap 8, external fan 9, the fan housing 10 of fuselage afterbody；Its
It is characterized in that：
Forefan 2 stirs the heat that stator 3, rotor 4, exciter stator 6, exciter rotor 7 generate, with drive end bearing bracket 1, engine base 5
It comes into full contact with, logical heat transfer is transmitted to the external world, and external fan 9 and the fan housing 10 of fuselage afterbody form axial ventilation road, brush rear end
The surface of lid 8 and engine base 5 is finally reached the purpose for reducing generator surface temperature.
