The end plate of end housing is equipped with rear axle housing after described, and the rear axle housing is recessed into the internal of rear end housing, and rear bearing is set
It sets in the internal of rear axle housing；
The circumferential side wall of end housing is equipped with the air inlet of multiple vertical bar types after described；
Fan blade is mounted on air blast in the shaft between nose shell and motor volute, cold air from the air inlet on rear end housing into
Enter in motor body, after air-cooled rotor, hot wind is discharged from the air outlet on nose shell and blows to volute of blower, and the wind that fan blade generates exists
Heat insulating air wall together is formed between electric machine casing and volute of blower.
It further, further include an infolding slot, the infolding slot is arranged on the ring flange of nose shell, nose shell and rear end
Shell contraposition connection, the ring flange fitting of forward and backward end housing, the flange portions edge of rear end housing is inserted into interior on nose shell ring flange
Buckle in slot is rolled over, then forward and backward end housing is linked together by riveting process.
Further, the forward and backward end housing is made by material during tensile, Sheet Metal Forming Technology.
A kind of motor for fume extractor provided by the utility model, due to using such structure, by by front axle
Set is recessed into the internal of nose shell, can shorten the spacing of motor and volute of blower, realizes the knot of gas heater fume extractor
Structure is compact, has sufficient position to remove installation cooling wind blade, fan blade air blast work, cold wind in the shaft between motor and volute of blower
Enter from the air inlet of rear end housing, air-cooled rotor, then be discharged from the air outlet of nose shell, effectively give motor radiating, guarantees electricity
Machine works normally, and extends the service life of motor；The short shaft design that turns is conducive to not allow to be also easy to produce when wind wheel high-speed rotation simultaneously
It shakes, to reduce operating noise.
Detailed description of the invention
Fig. 1 is the perspective view of the utility model.
Fig. 2 is the nose shell perspective view of the utility model.
Fig. 3 is the rear end housing perspective view of the utility model.
Specific embodiment
The embodiments of the present invention is described in detail with reference to the accompanying drawing, specific embodiment described herein is only
Only to explain the utility model, it is not used to limit the utility model.
As shown in Figure 1-3, a kind of motor for fume extractor, it includes shell 1, stator, rotor and shaft 2, described
Shell includes nose shell 11 and rear end housing 12, and the nose shell 11 is equipped with front axle bearing sleeve 3 and air outlet 4, and the front shaft sleeve 3 is recessed
The internal of nose shell 11 is fallen into, fore bearing is fixedly mounted on the internal of front shaft sleeve 3；
The air outlet 4 is fan-shaped, is arranged on the front end-plate of nose shell 11 with concentric circular fashion；
The end plate of end housing 12 is equipped with rear axle housing 5 after described, and the rear axle housing 5 is recessed into the internal of rear end housing 12, after
Bearing is fixedly mounted on the internal of rear axle housing 5；
The circumferential side wall of end housing is equipped with the air inlet 6 of multiple vertical bar types after described；
Shaft 2 drives the fan blade air blast in shaft, and cold air enters in motor body from the air inlet 6 on rear end housing, air-cooled
After rotor, hot wind is discharged from the air outlet 4 on nose shell and blows to volute of blower, motor housing and volute of blower in the work of fan blade
With one of heat insulating air wall of lower formation.
It further, further include an infolding slot 7, the infolding slot 7 is arranged on the ring flange 111 of nose shell 11, front end
Shell 11 and the contraposition of rear end housing 12 connect, and the ring flange fitting of forward and backward end housing, the flange portions edge of rear end housing is embedded in nose shell
