Abstract
The invention provides a brushless motor fan which comprises a hub, a blade, a rotor, a stator, a bearing chamber and a switch controller, wherein the hub, the blade, the rotor and the bearing chamber are integrally formed. According to the brushless motor fan, the hub, the blade, the rotor and the bearing chamber are integrally formed, the brushless motor fan has the advantages of light weight, less parts, material conservation, short axial length and good coaxiality and fan balance property; and the cooling effect on an armature, the switch controller and the like is good, and electronic parts are well sealed and protected.
Description
Technical field
The present invention relates to a kind of motor ventilating fan, particularly a kind of brushless electric machine fan.
Background technique
High-power external rotor electric machine (brushless electric machine) weight of existing technology is heavier, materials are many, part is many, axial length; Because the bearing chamber of fan blade and external rotor is respectively two parts; The balance of its coaxality and fan is difficult to guarantee, need carries out fine finishing to the inside and outside circle and the axial end of external rotor for this reason.
Summary of the invention
The object of the invention is to overcome the problems referred to above that existing technology exists, provide a kind of in light weight, part is few, material is economized, axially short, and the good brushless electric machine fan of the balance of coaxality and fan.
The objective of the invention is to realize like this: a kind of brushless electric machine fan comprises wheel hub, fan blade, rotor, stator, bearing chamber and on-off controller; Be characterized in that described wheel hub, fan blade, rotor and bearing chamber are one-body molded to be integral structure component.
Brushless electric machine fan of the present invention (claiming the external rotor electric machine fan again); Because fan blade, wheel hub, rotor and bearing chamber are one-body molded; Not only have in light weight, part is few (having saved the set screw of fan blade and external rotor etc.), material is economized (saving the end metal of external rotor), axially short, and the balance of coaxality and fan is good, the cooling of armature (main member of stator) and on-off controller etc. better (wheel hub radial and axial all have cooled blade), electronic section is had sealing and protective action well.
Description of drawings
Fig. 1 is the overall structure schematic representation of brushless electric machine fan of the present invention;
Fig. 2 is that partial structurtes and the cooling air of brushless electric machine fan of the present invention is to schematic representation.
Embodiment
Referring to Fig. 1, cooperate referring to Fig. 2, brushless electric machine fan of the present invention comprises wheel hub 1, fan blade 2, rotor 3, stator 4, bearing chamber 5 and on-off controller 6, wheel hub 1 wherein, fan blade 2, rotor 3 and bearing chamber 4 are one-body molded to be integral structure component.Shown in the figure, 7 is end cap, and 8 is axle, and 9 is fixed base.
Brushless electric machine fan of the present invention is owing to adopted above technological scheme, and its cooling air is to shown in the arrow among Fig. 2, and is all better to the cooling effect of wheel hub, armature and on-off controller.
Claims (1)
