Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing
And embodiment, this utility model is further elaborated.Should be appreciated that described herein specifically
Embodiment, only in order to explain this utility model, is not used to limit this utility model.
It should be noted that when element is referred to as " being fixed on " or " being arranged at " another element, and it can
With directly on another element or be connected on this another element.When an element is referred to as " connecting
In " another element, it can be directly to another element or be indirectly connected to this another yuan
On part.
Also, it should be noted the orientation term such as left and right, upper and lower in the present embodiment, it it is only phase each other
To concept or with the normal operating condition of product as reference, and should not be regarded as restrictive.
As shown in Fig. 1 to Fig. 3, Fig. 5, the external rotor electric machine of first embodiment of the present utility model includes electricity
Machine stator, rotor, bottom and clutch end lid 10.The bottom of this external rotor electric machine and motor stator
End fixing connect, rotor is formed with receiving chamber, and motor stator is arranged on receiving intracavity, and motor turns
First end of son is rotatably coupled with bottom, and clutch end lid 10 is fixedly connected on the second of rotor
On end and with rotor synchronous axial system, clutch end lid 10 is provided with multiple output shaft around rotor
The flabellum 11 of the circumferential direction distribution of 14, and multiple flabellum 11 is between motor stator and rotor,
Wherein, bottom is provided with wind guiding inlet, and clutch end lid 10 is additionally provided with wind-guiding outlet 12.
By the flabellum 11 being arranged on clutch end lid 10, when rotor rotates, flabellum 11 with
Rotor synchronous axial system, flabellum 11 carries out disturbance to the air between motor stator and rotor, then
The hot blast carrying heat is derived from wind-guiding outlet 12, derives electricity after hot blast due to the agitation of flabellum 11
Machine has been internally formed negative pressure, and the cold wind that outside temperature is relatively low is blown into from wind guiding inlet under suction function, cold
Wind is derived from wind-guiding outlet 12 after heat exchange in motor again, constantly takes away the heat that motor internal produces with this,
Thus reached the purpose of the lasting radiating and cooling to motor internal so that and the stable output power of motor, dynamic
Power exports while meeting demand, and the external rotor electric machine continuous type time is longer.
In the first embodiment, owing to clutch end lid 10 is with rotor synchronous axial system, and power is defeated
The output shaft 14 gone out on end cap 10 is direct power delivery section, in order to improve clutch end lid 10
Mechanical strength, therefore, the inner side of the close motor stator of clutch end lid 10 be provided with multiple radial direction strengthen
Rib 13, by the strengthening interaction between each radially ribs 13, thus strengthens clutch end lid
The overall mechanical strength of 10.
In the first embodiment, the quantity of wind-guiding outlet 12 is multiple, and the outlet 12 of multiple wind-guidings is for being opened in
The axial air-out in the region between adjacent two radial direction ribs 13 and the cover rim 15 of clutch end lid 10
Mouthful.As it is shown in figure 5, when rotor drives clutch end lid to rotate around the C direction of arrow, outside temperature
Spend relatively low wind constantly to enter from the wind guiding inlet of bottom, and after heat exchange, further along D arrow from axially
Wind-guiding outlet 12 derivation in direction, thus take away the waste heat that motor internal produces.
As depicted in figs. 1 and 2, multiple flabellums 11 are around between the circumferential direction etc. of the output shaft 14 of rotor
It is distributed away from ground.So can by wind from each radially air outlet derive equably, thus each to motor internal
Individual region carries out uniform radiating and cooling, it is to avoid the situation generation that local temperature is overheated.Specifically, multiple lead
Wind outlet 12 is distributed equally spacedly around the circumferential direction of the output shaft 14 of rotor.
Further, the region between adjacent two radial direction ribs 13 is equipped with at least one wind-guiding outlet 12,
Can only offer wind-guiding outlet 12, it is also possible to offer the wind-guiding outlet of 2,3,4 etc. quantity
12.Preferably, the region between adjacent two radial direction ribs 13 and the cover rim 15 of clutch end lid 10
Hollow out is a wind-guiding outlet 12, and the opening so making each wind-guiding outlet 12 is bigger, wind-guiding outlet 12
Air output also increase, be conducive to will carry heat hot blast derive.
In the first embodiment, radially ribs 13 is provided with 9 equably, thus the wind-guiding that hollow out is formed
Outlet 12 is also 9.
In the second embodiment of the present utility model, compared with first embodiment, the wind-guiding of the second embodiment
Outlet 12 is radial direction air outlet, and multiple radial direction air outlet is opened in the cover rim 15 of clutch end lid 10
On, the cover rim 15 between adjacent two radial direction ribs 13 can offer 1 radially air outlet, it is possible to
To offer 2,3, multiple radial direction air outlets such as 4.As shown in Figure 4, when rotor is along A arrow
When rotating and drive flabellum 11 agitation air, outside cold wind is constantly blown into from the wind guiding inlet of bottom, then warp
Heat exchange is taken away hot blast by these radial direction air outlets along the blowout of direction shown in B arrow and is carried out radiating and cooling.With first
Embodiment is compared, and the second embodiment is in addition to above-mentioned difference, and remaining structure is the most identical, does not repeats them here.
These are only preferred embodiment of the present utility model, not in order to limit this utility model, all
Any amendment, equivalent and the improvement etc. made within spirit of the present utility model and principle, all should comprise
