On wrapping post time, there is spacing i.e. this breach in line, at rotor punching during rotating, air-flow can pass through breach pair
Rotor carries out radiating and cooling, and then improves the service life of motor.
In the middle of positioning section around line segment for copper cash residual around, spacing section for carrying out spacing to copper cash, prevents copper cash from skidding off
Winding slot, in order to improve the anti-extrusion ability of spacing section and the spacing section of bonding strength followed around line segment and connective stability, therefore
Spacing section and connected by joining section around line segment, the outer wall of this joining section takes the form of inclined plane, and increases and the contact area of copper cash, and then
Improve its restraining ability.The spacing section of curved shape of outer wall, improves the anti-pressure ability of spacing section, and reduces external force to limit
The power of influence of position section.
This utility model is further arranged to: described winding slot includes inner chamber and the exocoel being interconnected, and exocoel includes phase
Intercommunicated inlet and conducting room, the width of conducting room is more than the width of inlet, the trapezoidal shape of inner chamber.
By using technique scheme, after being full of copper cash on wrapping post, copper cash can fill winding slot, turns to reduce
Son rotates the noise produced, therefore conducting room is arranged to the width width more than inlet.Inner-cavity structure local locking copper cash
Effect.
This utility model is further arranged to: the length of described supporting section and the lenth ratio of positioning section are 1.1-1.3.
By using technique scheme, when the length of supporting section and the lenth ratio of positioning section are 1.1-1.3, coiling
Post anti-pressure ability and copper cash install stabilizing effect optimal.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of this utility model wrapping post.
Detailed description of the invention
Referring to figs. 1 through Fig. 2, embodiment of the present utility model is described further.
This utility model important component part: include punching body, punching body offers axis hole 20, punching body week
To several winding slot 10 is distributed, constitute between adjacent two winding slots 10 and have wrapping post 2.
Punching body includes inner ring 11 and outer ring 12, and wrapping post 2 includes interconnective supporting section 21 and positioning section 22,
Head end and the positioning section 22 of support section 21 connect, and end and the inner ring 11 of supporting section 21 connect, supporting section 21 and the company of positioning section 22
The upper composition in the place of connecing has a breach 20, and the diameter of supporting section 21 is incremental shape by head end to end, and positioning section 22 includes being connected with each other
Around line segment 22b and spacing section of 22a, the diameter of spacing section of 22a more than the diameter around line segment 22b, spacing section of 22a and around line segment
22b is connected by joining section, the inclined shape of outer wall of joining section, the curved shape of outer wall of spacing section of 22a, outside this spacing section of 22a
The radian of wall is 10 °.
Supporting section 21 is used for supporting positioning section 22, and positioning section 22 is for spacing copper cash, in order to ensure the resistance to compression of supporting section 21
Ability, therefore the structure of supporting section 21 is arranged to diameter by head end to end is incremental shape, improves and the joint face of inner ring 11
Long-pending, and then improve its structural stability, and the molding of breach 20 on supporting section 21 and positioning section 22 junction so that copper cash
On wrapping post 2 time, there is spacing i.e. this breach 20, at rotor punching during rotating, air-flow can pass through breach
20 pairs of rotors carry out radiating and cooling, and then improve the service life of motor.
In the middle of positioning section 22 around line segment 22b for copper cash residual around, spacing section of 22a, for carrying out spacing to copper cash, prevents
Copper cash skids off winding slot 10, in order to the anti-extrusion ability and spacing section of 22a improving spacing section of 22a follows the connection around line segment 22b
Intensity and connective stability, therefore spacing section of 22a and being connected by joining section 22c around line segment 22b, the outer wall of this joining section 22c in
Inclined plane shape, increases and the contact area of copper cash, and then improves its restraining ability.The spacing section of curved shape of 22a outer wall, improves
The anti-pressure ability of spacing section of 22a, and reduce the external force power of influence to spacing section of 22a.
Winding slot 10 includes inner chamber 103 and the exocoel being interconnected, and exocoel includes inlet 101 and the conducting being interconnected
Room 102, the width of conducting room 102 is more than the width of inlet 101, the trapezoidal shape of inner chamber 103.
After being full of copper cash on wrapping post 2, copper cash can fill winding slot 10, the noise produced to reduce rotor to rotate,
Therefore conducting room 102 is arranged to the width width more than inlet 101.The effect of inner chamber 103 structure partial locking copper cash.
When the length of supporting section 21 and the lenth ratio of positioning section 22 are 1.1-1.3, wrapping post 2 anti-pressure ability and
The stabilizing effect that copper cash is installed is optimal.
If the lenth ratio of the length of supporting section 21 and positioning section 22 is more than 1.1-1.3, the length of positioning section 22 reduces,
The restraining ability of copper cash is reduced by positioning section 22, and then reduces the mounting stability of copper cash.
If the lenth ratio of the length of supporting section 21 and positioning section 22 is less than 1.1-1.3, winding slot 10 accommodates copper cash
The number of turns reduces, and then affects the operation of motor.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, the skill of this area
Art personnel carry out common variations and alternatives in the range of technical solutions of the utility model all should be included in guarantor of the present utility model
In the range of protecting.
