Low precision in blower fan system assembling process, blast leakage is serious between movable vane wheel and impeller chimney, causes the reduction of fan section efficiency.
Axiality especially between stator center and iron casing center is unable to reach required precision, causes smart in whole installation process
Spend low, motor functional reliability is poor.
Utility model content
A kind of the shortcomings that the applicant is directed in above-mentioned existing production technology, there is provided dust catcher brushless electric machine rational in infrastructure
Structure, stator center and the axiality requirement of iron casing inner pedestal are thereby may be ensured that, precision is high, meets requirement.
Technical scheme is as follows used by the utility model：
A kind of dust catcher brushless motor structure, including rotor, stator, the both ends point of the stator are installed on the rotor
Skeleton is not installed, the outside of the stator is cased with iron casing, and the outside of the iron casing is cased with the cabinet supporting with it,
And iron casing and cabinet are locked by multiple screws in its end face；Movable vane wheel, the modeling are also equipped with the rotor
Air-ducting ring is installed on the outside of material casing, the air-ducting ring is located at the outside of movable vane wheel；The cabinet and air-ducting ring it is outer
Portion is covered with impeller chimney simultaneously, formed with gap between the internal face of the impeller chimney and the outer ring of air-ducting ring；A left side for the stator
End is provided with end cap, and the outside of the end cap coordinates installation electric capacity.
Further improvement as above-mentioned technical proposal：
The central axis of the stator is with the central axis of iron casing internal bearing block in same center.
Iron casing is wrapped in inside by the cabinet.
Multiple blades are provided with the cylindrical circumferential direction of the air-ducting ring.
The beneficial effects of the utility model are as follows：
The utility model is compact-sized, reasonable, easy to operate, can by using iron casing and cabinet mating reaction
Effectively to ensure stator center and the requirement of iron casing internal bearing block axiality, installation accuracy is substantially increased, can be applied
In the occasion of height operating, usual rotating speed can reach the r/min of 3-10 ten thousand.
Compared with traditional electric fan, by the effect of impeller chimney, using axial air outlet, it is easy to the application of various occasions.
