In rotating shaft on install and oriented casing internal is installed in rotating shaft in the rear flabellum dried outside oriented casing, the preceding fan blade chamber blown
The preceding flabellum of wind.
By above-mentioned technical proposal, during work, flabellum in preceding fan blade chamber is dried in fan blade chamber backward, is located at simultaneously
The flabellum in fan blade chamber is dried to outside casing afterwards, will so be blown from casing front end to casing internal, from casing rear end by casing
Internal wind is taken away, and in this process, the air temperature moved from casing front end into casing is relatively low, when these enter in casing
Afterwards, the heat that motor work is sent will be absorbed by the wind entered from casing front end and be gone out from casing rear end, air stream in casing
Fast big, heat will be distributed in big air quickly, therefore temperature is difficult to rise too high during motor work, and motor would operate in safety
Temperature is small, motor working stability, long service life；Because preceding flabellum and rear flabellum are installed in rotating shaft, so operationally
Extra exterior power device, which need not be installed, can just work, and velocity of rotation becomes with the change of motor rotation speed
Change, when motor speed is very fast, it is more more that the motor feels hot, and now preceding flabellum and rear flabellum also rotating speed are very fast, can be by casing
Interior heat sheds in time, while when axis of rotation is slower, it is smaller that the motor feels hot, and now, preceding flabellum and rear flabellum rotating speed compared with
Slowly, the heat in casing can also be shed in time, good heat dissipation effect.
It is preferred that, fin is provided with the side wall of the casing, direction of the fin along parallel shaft is set, and wing
Piece is extended at preceding fan blade chamber at rear fan blade chamber, and the fin is internally provided with for preceding fan blade chamber and rear fan blade chamber to be turned on

It is preferred that, the vertical sectional shape of the fin is triangle, and the air channel is and concentric tri-angle-holed of fin.
By above-mentioned technical proposal, in order that fin when being contacted with ground, the support to casing is more stable, by fin
Triangularity is set, when motor works, it will in heat transfer to fin, in order to increase the contact area of fin and air,
And also to so that fin strength is higher, air channel is set into triangularity, the Thickness Strength of such fin each several part is consistent,
Fin is operationally not easy to break, and also ensure that air channel is larger, the contact area of increase fin and air.
It is preferred that, the preceding fan blade chamber is respectively arranged with ventilating opening with rear fan blade chamber on the side wall of stator.
By above-mentioned technical proposal, ventilating opening is provided with the side wall of stator side in preceding fan blade chamber and rear fan blade chamber,
Extraneous wind from ventilating opening will can be sent into casing internal by flabellum before so so that the heat of casing internal is absorbed, afterwards
The higher air of temperature in casing can be suctioned out by rear flabellum again so that the temperature in casing is quickly reduced, motor is by work
Under suitable temperature environment.
It is preferred that, the preceding fan blade chamber on side wall of the rear fan blade chamber away from stator with being respectively arranged with heat emission hole.
By above-mentioned technical proposal, in order that extraneous cold wind is convenient enters in preceding fan blade chamber, also for causing rear wind
The higher air of temperature is discharged to the external world in time in phyllocyst, and radiating is both provided with away from stator side in preceding fan blade chamber and rear fan blade chamber
Hole, so, cold air will be entered in preceding fan blade chamber by heat emission hole, then accelerate into casing internal by preceding flabellum,
Gone out again from rear fan blade chamber is entered, and from heat emission hole in entering outside air in the presence of rear flabellum afterwards, complete casing
The exchange of internal heat so that the heat of casing internal is quickly dispersed into outside air, motor radiating performance is good.
It is preferred that, projection of the heat emission hole with ventilating opening in the plane of vertical rotation axis is mutually staggered.
By above-mentioned technical proposal, in order to prevent that then the extraneous debris entered from directly entering again from ventilating opening from heat emission hole
Into casing internal so that motor internal is damaged, and ventilating opening is in staggered distribution with heat emission hole, so the debris in the external world is from heat emission hole
It after, will be difficult to enter casing internal from ventilating opening directly with wind, play certain lattice gear effect.
It is preferred that, the guard for preventing extraneous particulate matter from entering is provided with the heat emission hole.
By above-mentioned technical proposal, during in order to prevent that preceding flabellum from working, inside extraneous debris suction casing, in radiating
Guard is provided with hole, will effectively prevent extraneous particulate matter from entering motor internal.
In summary, the utility model having the beneficial effect that in contrast to prior art：By behind casing front end and casing
End is provided with the preceding fan blade chamber and rear fan blade chamber of connection, can drive preceding flabellum and rear flabellum one by rotating shaft when motor works
Work is played, the heat of casing internal is dispersed into outside air by the air of flowing so that the temperature of casing internal is relatively low,
When in use, motor is hardly damaged, long service life.
