Embodiment
To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with the specific embodiment of the invention and
Technical solution of the present invention is clearly and completely described in corresponding attached drawing.Obviously, described embodiment is only the present invention one
Section Example, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art are not doing
Go out all other embodiments obtained under the premise of creative work, belong to the scope of protection of the invention.
As shown in Figure 1, a kind of motor, including housing 1, stator 2 and rotation axis 3, stator 2 are arranged in housing 1, housing 1
First end has end cap 4.It is threaded through in rotation axis 3 in stator 2, through hole can be set in actual fabrication, on end cap 4, and (figure is not
Show), rotation axis 3 is stretched out end cap 4 by through hole.Fan blade 5 is provided with rotation axis 3, in the axis side along stator 2
To fan blade 5 is between stator 2 and end cap 4；When rotation axis 3 rotates, fan blade 5 can certain driving air-flow the heat of stator 2 is passed
It is delivered on end cap 4.Using such technical solution, the air-flow between stator 2 and end cap 4 can be driven to flow speed by fan blade 5
Degree, makes the heat of stator 2 quickly be delivered on end cap 4.And motor is in use, end cap 4 can be bonded with external environment component,
Heat on end cap 4 can so be directly delivered on external environment component, therefore this programme can make stator quick heat radiating,
Temperature rise is thereby reduced, improves the service life of motor.Wherein, the material of fan blade 5 can be metal or plastics, but and unlimited
In this.
Specifically, as shown in Figure 1, fan blade 5 includes blade 51, blade 51 is fixedly connected in rotation axis 3.Blade 51 can be with
It is welded in rotation axis 3, can also being connected by screw etc. other, can to realize that blade 51 is fixedly connected with rotation axis 3 any
Mode.Further, the quantity of blade 51 is two or more, and uniformly distributed along the circumferential direction of rotation axis 3, passes through multiple blades 51
Air flow is driven, and then improves heat dissipation effect.
As a kind of embodiment, as shown in Figure 2,3, fan blade 5 further includes installation set 52, and installation set 52 is set in rotation
On axis 3, blade 51 is fixedly connected on the outer wall of installation set 52.Wherein, the quantity of blade 51 is two or more, two or more leaf
Piece 51 is uniformly distributed along the circumferential direction of installation set 52.Specifically, it is interference fit between installation set 52 and rotation axis 3, to ensure wind
The fastness installed between leaf 5 and rotation axis 3.In actual installation, installation set 52 can be sleeved on rotation by way of cold pressing
In shaft 3.
Further, as shown in Figure 1, stator 2 has the heat dissipation end face 21 of face end cap 4, it is provided with end face 21 of radiating
Conducting-heat elements 6, the shape of conducting-heat elements 6 and the shape for end face 21 of radiating match.So can be by conducting-heat elements 6 to heat dissipation
Gap between end face 21 and end cap 4 is filled, and the air gap between stator 2 and end cap 4 is become very little.In actual fabrication
In, the thermal conductivity factor of conducting-heat elements 6 is more than the thermal conductivity factor of air, can so make transmission speed of the heat of stator 2 to end cap 4
Degree becomes faster.Specifically, conducting-heat elements 6 are fixedly connected on by way of injection on heat dissipation end face 21, when being not limited in
This.
Above example makes the present invention have design rationally, simple in structure, effectively controls temperature rise, makes the service life of motor
The advantages of being improved.
The foregoing is merely the embodiment of the present invention, is not intended to limit the invention, for those skilled in the art
For member, the invention may be variously modified and varied.Any modification within the spirit and principles of the invention, being made,
Equivalent substitution, improvement etc., should be included within scope of the presently claimed invention.
