Abstract
The utility model discloses band ventilation structural electromotor armature spindle, equipped with axial hole, it is characterised in that：The outer wall of the armature spindle is equipped with the open slot of axial direction in interlude, and open slot is run through armature spindle outer wall between axial hole, fixed in axial hole that impeller is housed；The open slot circumference lays three, and the impeller is equipped with two, and two impellers are configured respectively close to the both ends of the open slot.The utility model can realize the good ventilation of motor internal, prevent motor long-play from overheating, and improve motor service life.
Description
Technical field
It the utility model is related to a kind of fan motor for automobile, and in particular to a kind of rotor axis of electric.
Background technology
The fan motor for automobile of the prior art, since the ventilation condition of motor internal is poor, heat caused by motor operation
It is not easy to discharge, so often being run under the operating condition of higher temperature, may have not only caused motor long-play to overheat, but also
It can make the easy aging of motor part and reduce motor service life.
The content of the invention
In view of the deficiency of background technology, the purpose of this utility model aims to provide a kind of the good logical of achievable motor internal
Wind, prevents motor long-play from overheating, and improves the band ventilation structural electromotor armature spindle of motor service life.
The utility model is adopted the following technical scheme that to complete：
Band ventilation structural electromotor armature spindle, equipped with axial hole, it is characterised in that：The outer wall of the armature spindle is set in interlude
There is the open slot of axial direction, open slot is run through armature spindle outer wall between axial hole, fixed in axial hole that leaf is housed
Wheel.
The open slot circumference lays three, and the impeller is equipped with two, and two impellers are respectively close to the open slot
Both ends are configured.
The impeller has integrally formed blade and outer shroud, and the cylindrical of outer shroud is interference fitted between axial hole.
The rotor axis of electric of above-mentioned technical proposal, outer wall are equipped with the open slot of axial direction in interlude, and open slot will turn
Sub- axis outer wall is run through between axial hole, and opening trough_like can thus make the front and rear space of motor internal into ventilation gap
It is more preferable to complete perforation, to realize that the good ventilation of motor internal provides necessary condition.Further, in the axial hole of armature spindle
Fixation is equipped with impeller, and when motor works, impeller is internally formed action of blast with armature spindle high-speed rotation in armature spindle, and then
Ventilation water conservancy diversion is formed between space before and after motor internal by open slot, the good ventilation of motor internal is then realized, prevents
Only motor long-play overheats, and improves motor service life.
Brief description of the drawings
The utility model has drawings described below：
Fig. 1 is the structure diagram of the utility model,
Fig. 2 is the A-A sectional views of Fig. 1.
Embodiment
As shown in the figure, the band ventilation structural electromotor armature spindle of the utility model, equipped with axial hole 4, outside the armature spindle 1
