Embodiment
Embodiments of the invention are described below in detail, the example of the embodiment is shown in the drawings.Below with reference to
The embodiment of accompanying drawing description is exemplary, it is intended to for explaining the present invention, and is not considered as limiting the invention.
Below with reference to the accompanying drawings motor 20 according to embodiments of the present invention is described.
As Figure 1-Figure 8, motor 20 according to embodiments of the present invention includes stator 100 and rotor 300.
Stator 100 includes stator core 110, the Insulating frame 120 that is located on stator core 110 and around being located at Insulating frame
Stator winding (not shown) on 120.Have in stator 100 positioned at the fore bearing room 210 and position of the front end of stator core 110
Rear bearing chamber 130 in the rear end of stator core 110 (in fore-and-aft direction such as accompanying drawing shown in arrow A).Stator 100 is provided with stator
The fresh air inlet 220 and exhaust vent 160 that the inner chamber of iron core 110 is in communication with the outside, fresh air inlet 220 are located at fore bearing room 210 and stator
Between iron core 110, and exhaust vent 160 is between rear bearing chamber 130 and stator core 110.Rotor 300 is located in stator 100,
The armature spindle 310 of rotor 300 passes through the fore bearing 400 being located in fore bearing room 210 and the rear bearing being located in rear bearing chamber 130
500 are supported in stator 100, and the rear end of rotor 300 is provided with cooling wind blade 320.
Motor 20 according to embodiments of the present invention, by setting the air-out that the inner chamber of stator core 110 is in communication with the outside
Hole 160 and fresh air inlet 220, and rotor 300 rear end face set cooling wind blade 320, so when rotor 300 when rotated, lead to
Cross fresh air inlet 220 to import the cold air in the external world, the outer peripheral face and stator core 110 that the cold air being imported into passes through rotor 300
Inner peripheral surface between gap flow to front end, and the heat of intracavitary in stator core 110 is taken away in flow process, finally by
Exhaust vent 160 is discharged, so as to reduce the overall temperature rise of motor 20.Therefore, motor 20 according to embodiments of the present invention has radiating
The advantages that effect is good.
Below with reference to the accompanying drawings motor 20 according to the specific embodiment of the invention is described.
In some specific embodiments of the present invention, as Figure 1-Figure 8, motor 20 according to embodiments of the present invention includes
Stator 100 and rotor 300.
As shown in figures 1 to 6, fore bearing room 210 is limited by the preceding metallic support 200 for being located at the front end of stator core 110.
Preceding metallic support 200 has the annular endplate 240 positioned at the outside of fore bearing room 210, and fresh air inlet 220 is located on annular endplate 240.
Specifically, as shown in figure 8, fresh air inlet 220 is elongated hole (the i.e. arc along the circumferentially extending of annular endplate 240
Hole), fresh air inlet 220 can be multiple and along annular endplate 240 circumferential spaced sets.So can before guarantee metal branch
In the case of the structural strength of frame 200, the surface area of metallic support 200 before maximally utilising, the face of guarantee fresh air inlet 220
Product, so as to improve the radiating effect of fresh air inlet 220.
Wherein, as shown in figure 1, the front end face of stator core 110 passes through plastic formation mating holes 140, preceding metallic support 200
It is interference fitted with mating holes 140, so as to realize the location and installation of preceding metallic support 200.
Because the cost of the preceding metallic support 200 of stretching will be well below cast aluminium of the prior art or injection cost, this
Sample can reduce material cost.And because fore bearing room 210 need not carry out secondary operation, it is possible thereby to be easy to the He of fore bearing 400
The axiality of bearing 500 afterwards, so as to reduce the noise of motor 20.
Further, as shown in figure 8, preceding metallic support 200 is provided with ground connection mounting hole 230, ground connection mounting hole 230 can be with
It is lateral opening for varus., can be by earthing or grounding means by coordinating in ground connection mounting hole 230 when motor 20 needs to set earthing or grounding means
Screw be directly installed on before on metallic support 200, improve the security that motor 20 is run.
In some specific examples of the present invention, as shown in fig. 6, after rear bearing chamber 130 is by being coated on stator core 110

Plastic packaging support 190, exhaust vent 160 are arranged on plastic packaging support 190.
It is stator 100 by being molded after the coiling winding of stator core 110, after injection, determines it is possible thereby to save
Sub 100 postorder treatment process, so as to save substantial amounts of man power and material, simplify manufacture craft, and then shorten fabrication cycle
With the turnaround time of semi-finished product.
Also, bearing chamber 130 after directly being formed by rear injection molded layers 180, it can store for supporting the rear end of armature spindle 310
Rear bearing 500, can so save the rear end cap of motor of the prior art, not only simplify assembling, and can reduce
Material cost.
As shown in Figure 2, Figure 5 and Figure 6, the rear end face of plastic packaging support 190 is provided with deep gouge 150, and exhaust vent 160 is located at deep gouge
On 150 inwall.Deep gouge 150 can be multiple, and deep gouge 150 is substantially fan-shaped, and multiple deep gouges 150 are along after plastic packaging support 190
The circumferential spaced set of end face.It is possible thereby to increase the area of dissipation of plastic packaging support 190 using deep gouge 150, so as to beneficial to electricity
The heat of machine 20 distributes.
Alternatively, in order to further improve the radiating effect of motor 20, the wall of deep gouge 150 (does not show provided with mesh in figure
Go out), the cold air that the heat in such stator 100 further can be entered by the mesh directly carries out heat exchange.
Wherein, exhaust vent 160 can be multiple and along plastic packaging support 190 circumferentially-spaced arrangements.
In some specific embodiments of the present invention, fore bearing room 210 can also be by being coated on the front end of stator core 110
Preceding injection molded layers (not shown) limits.The preceding injection molded layers have the annular end positioned at the fore bearing outside, enter
Air holes 220 is arranged on the annular end.
By being molded after the coiling winding of stator core 110, the postorder treatment process of stator 100 can be saved, so as to
Substantial amounts of man power and material is saved, simplifies manufacture craft, and then shortens the turnaround time of fabrication cycle and semi-finished product.
Also, fore bearing room 210 is directly formed by the preceding injection molded layers, can be stored for after supporting armature spindle 310
The fore bearing 400 at end, the drive end bearing bracket of motor of the prior art can be so saved, not only simplify assembling, and can drop
Low material cost.
Alternatively, rear bearing chamber 130 is limited by the rear metallic support (not shown) for being located at the rear end of stator core 110
Go out, exhaust vent 160 is set in the rear on metallic support.
In some specific embodiments of the present invention, as shown in fig. 6, being provided with metal end 131 in rear bearing chamber 130
(BB lids), rear bearing 500 are arranged in metal end 131.
Further, effect is imported in order to improve the cold wind of cooling wind blade 320, the rear edge of cooling wind blade 320 exceeds backward
The bottom wall of exhaust vent 160 and expose from exhaust vent 160, i.e., as viewed from exhaust vent 160, it can be seen that a part of cooling wind blade 320.Change
Yan Zhi, the rear end of cooling wind blade 320 are located at the rear of the bottom wall of exhaust vent 160.
Alternatively, cooling wind blade 320 can be linear, or arc.Preferably, as shown in figure 8, cooling wind blade
320 are arc and are multiple, are equally spacedly located on the rear end face of rotor 300.
