Description
Technical field
The utility model relates to technical field of motors, and in particular to a kind of brushless motor stator insulation framework.
Background technique
Currently, the common structure of the insulation framework (also referred to as insulation framework) being arranged on brushless motor stator iron core is by two
Skeleton is fastened from the both ends of stator core respectively, to carry out being coated with realization insulation, motor housing to each tooth of stator core
And it when electric motor end cap installation, generally requires bolt and fixes, therefore, need that recessed structure is arranged on the outer wall of insulation framework annular outer ring
For avoiding bolt, furthermore the recessed structure also has stress release effect, that is, insulation framework when coil winding machine coiling is avoided to occur
Deformation.But meanwhile recessed structure also brings some defects, as disclosed in patent document (application No. is 201620122783.5)
Insulation framework and motor, wherein the setting of recessed structure is specifically disclosed, as can be seen from Figure 1 because of the setting of recessed structure,
Spacing between recessed structure and the column on side becomes smaller, and is not easy line, while also will increase the hardly possible of the demoulding after edge skeleton forming
Degree.
Utility model content
Technical problem to be solved by the utility model is: overcoming above-mentioned defect in the prior art, provide a kind of with recessed
Enter structure and does not influence the brushless motor stator insulation framework of line and demoulding.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of brushless motor stator insulation framework,
Include:
The outer wall of annular outer ring, the annular outer ring is equipped with sunk structure, and the sunk structure is along the annular outer ring
Radially-inwardly recess；
The outer ledge of ring-shaped platform, the ring-shaped platform is connect with annular outer ring bottom；
The column of table top is set, and the column is opposite with sunk structure and the two spacing distance, opposite with column
Sunk structure inner sidewall be plane；It is plate as preferred column, and parallel with the plane on sunk structure inner sidewall；
For the teeth portion and the insulation framework main body that insulate of groove portion to motor stator core, the insulation framework main body
Top outer edge and ring-shaped platform inside edge connect.
Further, sunk structure has multiple and is uniformly arranged, and the quantity of the column and the quantity of sunk structure are identical.
What the utility model obtained has the technical effect that the inner sidewall of sunk structure being designed to plane, and is increased with this recessed
The spacing between structure and column is fallen into, makes to easily facilitate coiling, while being also easier to demould when insulation framework described in injection molding.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the brushless motor stator insulation framework in the utility model embodiment.
Fig. 2 is the top view of Fig. 1.
In figure: 1. annular outer rings, 2. sunk structures, 3. ring-shaped platforms, 4. columns, 501. slot insulation, the insulation of 502. teeth portion,
Barricade in 503..
Specific embodiment
The utility model is described in further detail presently in connection with attached drawing.These attached drawings are simplified schematic diagram,
Only illustrate the basic structure of the utility model in a schematic way, therefore it only shows composition related with the utility model, direction
It can be only used for helping the description to the feature in attached drawing with referring to (for example, upper and lower, left and right, etc.).Therefore, it is not limiting
Following specific embodiments are used in property meaning processed, and are only requested by appended claims and its equivalent form to limit
The range of the theme of protection.
See Fig. 1 and Fig. 2, a kind of brushless motor stator insulation framework, comprising:
The outer wall of annular outer ring 1, the annular outer ring 1 is equipped with sunk structure 2, and the sunk structure 2 is along the annular
The radially-inwardly recess of outer ring 1；
The outer ledge of ring-shaped platform 3, the ring-shaped platform 3 is connect with annular outer ring bottom；
The column 4 of the plate of table top is set, the column 4 is opposite with sunk structure 2 and the two spacing distance, with
The inner sidewall of the opposite sunk structure 2 of column 4 is plane, and plane is parallel with plate column；
For the teeth portion and the insulation framework main body that insulate of groove portion to motor stator core, the insulation framework main body
Top outer edge connect with the inside edge of ring-shaped platform 3.Specifically, insulation framework main body includes: slot insulation 501, tooth
Portion's insulation 502 and interior barricade 503；The top outer edge of slot insulation 501 is connect with the inside edge of the ring-shaped platform 3；Tooth
Portion insulation 502 be arranged between two neighboring slot insulation 501, teeth portion insulation 502 left and right sides edge respectively with slot insulation 501
The top of left and right sides edge connects；Interior barricade 503 include top barricade and 2 lateral retaining walls, the bottom of the top barricade with
The inside edge connection of teeth portion insulation 502,2 lateral retaining walls set up separately in the two sides of top barricade, the top of 2 lateral retaining walls respectively with
The connection of top barricade left and right ends, the lower part of 2 lateral retaining walls are connect with the inside edge for the slot insulation for being located at its two sides respectively.Make
Used time, slot insulation 501 are inserted into motor stator core slot, right on the end face of one end that teeth portion insulation is located at stator core teeth portion
When motor stator teeth portion coiling, interior barricade 503 is for preventing coil from slipping.
The sunk structure (2) has 6 and is uniformly arranged, the quantity and the quantity phase of sunk structure (2) of the column (4)
Together.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not
It is confined to this, anyone skilled in the art is within the technical scope disclosed by the utility model, practical according to this
Novel technical solution and its design is subject to equivalent substitution or change, should be covered within the scope of the utility model.
