Specific implementation mode
It is specific below in conjunction with the utility model to keep the purpose of this utility model, technical solution and advantage clearer
Technical solutions of the utility model are clearly and completely described in embodiment and corresponding attached drawing.Obviously, described embodiment
Only it is the utility model a part of the embodiment, instead of all the embodiments.Based on the embodiments of the present invention, this field
The every other embodiment that those of ordinary skill is obtained without making creative work, belongs to the utility model
The range of protection.
As shown in Figure 1, a kind of motor, including shell 1, stator 2 and rotary shaft 3, stator 2 are arranged in shell 1, shell 1
First end has end cap 4.It is threaded through in rotary shaft 3 in stator 2, through-hole can be arranged in actual fabrication, on end cap 4, and (figure is not
Show), so that rotary shaft 3 is stretched out end cap 4 by through-hole.Fan blade 5 is provided in rotary shaft 3, along the axis side of stator 2
To fan blade 5 is between stator 2 and end cap 4；When rotary shaft 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 transmitted 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 in this way be directly delivered on external environment component, therefore this programme can make stator rapid cooling,
Wen Sheng is thereby reduced, the service life of motor is improved.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 rotary shaft 3.Blade 51 can be with
It is welded in rotary shaft 3, can also being connected by screw etc. other, can to realize that blade 51 is fixedly connected with rotary shaft 3 arbitrary
Mode.Further, the quantity of blade 51 is two or more, and uniformly distributed along the circumferential direction of rotary shaft 3, passes through multiple blades 51
Air flowing 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, more than two leaves
Piece 51 is uniformly distributed along the circumferential direction of installation set 52.Specifically, it is interference fit between installation set 52 and rotary shaft 3, to ensure wind
The fastness installed between leaf 5 and rotary shaft 3.In actual installation, installation set 52 can be sleeved on rotation by way of cold pressing
In shaft 3.
Further, it as shown in Figure 1, stator 2 has the heat dissipation end face 21 of face end cap 4, is provided on end face 21 of radiating
Conducting-heat elements 6, the shape and the shape of heat dissipation end face 21 of conducting-heat elements 6 match.It in this way 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 made to become very little.In actual fabrication
In, the thermal coefficient of conducting-heat elements 6 is more than the thermal coefficient of air, can make the heat of stator 2 to the transmission speed of end cap 4 in this way
Degree becomes faster.Specifically, conducting-heat elements 6 are fixedly connected on by way of injection molding on heat dissipation end face 21, when being not limited in
This.
Above example makes the utility model have reasonable design, simple in structure, effectively controls Wen Sheng, makes the use of motor
The advantages of service life is improved.
The above description is only the embodiments of the present invention, is not intended to limit the utility model, for this field
