Abstract
The utility model discloses a kind of stator punching and its brushless motors of application, wherein stator punching includes yoke portion, teeth portion, line embedding groove and centre bore, the quantity of the line embedding groove is 12 slots, the outer diameter D in the yoke portion is 79mm-89mm, the stator punching of this structure can improve motor performance after being applied to brushless motor, and reduce the dosage of enameled wire and stator punching material, although will increase the Ferrite Material used on rotor, but, since the price accounting of enameled wire in motor and stator punching material is big, and with market fluctuation, Ferrite Material price steadiness, it is at low cost, so the totle drilling cost of motor can be reduced.
Description
Technical field:
The utility model relates to a kind of stator punching and its brushless motors of application.
Background technique:
The motor part cost of brushless motor mainly has this three parts of silicon steel, enameled wire and magnetic material, optimization stator punching
Piece design is not only related to motor performance, also closely related with the cost of entire motor, passes through optimization stator punching each section
Dimension scale can reduce the dosage of enameled wire and silicon steel, because the price accounting of this part is big, and with market fluctuation, and turn
The Ferrite Material price steadiness used on son, and it is at low cost, enameled wire can be reduced by increasing Ferrite Material dosage
The decline of motor assembly sheet is realized with the dosage of silicon steel.
Utility model content:
The purpose of the utility model is to provide a kind of stator punching and its brushless motors of application, by optimizing stator punching
Size reduce the dosage of enameled wire and silicon steel, to reduce the cost of motor.
The purpose of this utility model is achieved by following technical proposals:
A kind of stator punching, including yoke portion, teeth portion, line embedding groove and centre bore, the quantity of the line embedding groove is 12 slots, described
The outer diameter D in yoke portion is 79mm-89mm.
The diameter of centre bore described above is d, and the ratio range of d/D is 0.6-0.7.
Teeth portion width described above is H1, and the ratio range of H1/d is 0.068-0.085.
Yoke portion described above width is H2, and the ratio range of H2/H1 is 0.75-0.85.
Stator punching is using made of silicon steel material.
A kind of brushless motor, including stator assembly and rotor assembly, the stator module includes stator core, the stator
Iron core is superimposed to be formed by several stator punchings described above.
Rotor assembly described above includes rotor core and magnetic shoe, and the magnetic shoe is using made of Ferrite Material.
The utility model compared with prior art, has the effect that
1) a kind of stator punching, including yoke portion, teeth portion, line embedding groove and centre bore, the quantity of the line embedding groove are 12 slots, institute
The outer diameter D for stating yoke portion is 79mm-89mm, and the stator punching of this structure can improve motor performance after being applied to brushless motor,
And the dosage of enameled wire and stator punching material is reduced, although will increase the Ferrite Material used on rotor, due to
The price accounting of enameled wire and stator punching material is big in motor, and with market fluctuation, Ferrite Material price steadiness, cost
It is low, it is possible to reduce the totle drilling cost of motor.
2) diameter of centre bore is d, and the ratio range of d/D is 0.6-0.7, and the stator punching of this structure is applied to nothing
Motor performance can more be improved after brush motor, and can more reduce the dosage of enameled wire and stator punching material, turned although will increase
The Ferrite Material used on son, still, since the price accounting of enameled wire in motor and stator punching material is big, and with city
Field wave is dynamic, Ferrite Material price steadiness, at low cost, so can more reduce the totle drilling cost of motor.
3) the teeth portion width of stator punching is H1, and the ratio range of H1/d is 0.068-0.085, the stator of this structure
After punching is applied to brushless motor, improve that motor performance effect is more preferable, and can more reduce enameled wire and stator punching material
Dosage, although will increase the Ferrite Material used on rotor, due to the valence of enameled wire and stator punching material in motor
Lattice accounting is big, and with market fluctuation, Ferrite Material price steadiness, at low cost, so can more reduce the totle drilling cost of motor.
4) the yoke portion width of stator punching is H2, and the ratio range of H2/H1 is 0.75-0.85, and the stator of this structure rushes
After piece is applied to brushless motor, the effect for improving motor performance is best, and can most reduce enameled wire and stator punching material
Dosage, although will increase the Ferrite Material used on rotor, due to the valence of enameled wire and stator punching material in motor
Lattice accounting is big, and with market fluctuation, Ferrite Material price steadiness, at low cost, so can most reduce the totle drilling cost of motor.
5) a kind of brushless motor can improve motor as using a kind of stator punching described in the utility model
Performance, and the dosage of enameled wire and stator punching material is reduced, reduce motor cost.
