Description
Technical field
The utility model relates to a kind of motor component, especially a kind of stator punching.
Background technique
Motor can generate a large amount of heat in operation, can all design wind-guiding knot in the stator of motor and rotor thus
Structure, by motor operate in the kinetic energy that generates the heat inside motor is taken away by outside air, allow winding at work can
Normal temperature is kept, guarantees that motor runs well.Once but motor occur short circuit or overload phenomenon, the temperature of winding will
It sharply increases, strong influence is caused to the operating of motor, winding can be blown when serious or motor is allowed to explode.
Utility model content
The utility model aiming at the shortcomings in the prior art, provides brushless high density wound stator punching, the punching of this stator
Piece can wind at least 15% winding more, with making power more powerful under homalographic, while have good radiator structure, no
Winding can be allowed to overheat.
In order to solve the above-mentioned technical problem, the utility model is addressed by following technical proposals: brushless high density around
Group stator punching, including yoke portion, the yoke portion includes inner circle, and uniform circular is provided with several teeth portion in the inner circle,
It is provided with winding slot between the adjacent teeth portion, it is characterized in that, the winding slot includes two sides and bottom edge, described
Bottom edge includes left side bottom and right side bottom, has angle between the left side bottom and the right side bottom, and the angle exists
Between 120 ° to 150 °, there is arc transition between the side and the bottom edge.
In above-mentioned technical proposal, it is preferred that the yoke portion includes upper yoke surface and lower yoke surface, the upper yoke surface and described
Lower yoke surface between within the round heart be that center uniform circular is provided with several fixed strips, set between the adjacent fixed strip
It is equipped with air flue.
In above-mentioned technical proposal, it is preferred that the upper yoke surface and the lower yoke surface edge be provided with several with
The opaque disk of covering is played the role of in the air flue cooperation.
In above-mentioned technical proposal, it is preferred that be provided with barrier sheet at the top of the teeth portion.
In above-mentioned technical proposal, it is preferred that the yoke portion and the teeth portion surface are coated with insulated paint.
In above-mentioned technical proposal, it is preferred that the yoke portion is made of 3D printing technique.
The utility model is a kind of novel stator punching, by the redesign to stator punching yoke portion structure, so that fixed
The yoke portion of sub- punching than existing stator can more windings 15% winding so that the power of this punching is more in the punching of same size
Height increases bring heat dissipation problem to solve winding, this punching has also redesigned lamination structure.Compared to previous integral type
Punching, this punching use catamaran type, be both divided into yoke surface and lower yoke surface, and be provided with air flue, pole between upper yoke surface and lower yoke surface
Big increases heat dissipation performance, while using being manufactured by 3D printing technique, reducing manufacture difficulty, is suitable for large-scale production.
Compared with prior art, the utility model has the beneficial effects that this stator punching can wind more at least 15% around
Group with making power more powerful under homalographic, while having good radiator structure, winding will not be allowed to overheat.
Detailed description of the invention
Fig. 1 is the utility model schematic top plan view.
Fig. 2 is the utility model schematic side view.
Specific embodiment
The utility model is described in further detail With reference to embodiment.
Embodiment 1: as shown in Figure 1 to Figure 2, brushless high density wound stator punching, including yoke portion 1, the yoke portion 1
Including inner circle 2, uniform circular is provided with several teeth portion 3 in the inner circle 2, be provided between the adjacent teeth portion 3 around
Wire casing 4, the winding slot 4 include two sides 41 and bottom edge 42, and the bottom edge 42 includes left side bottom and right side bottom, described
Left side bottom and the right side bottom between have angle, the angle between 120 ° to 150 °, the side 41 with
There is arc transition between the bottom edge 42.The yoke portion 1 includes upper yoke surface 11 and lower yoke surface 12, the upper yoke surface 11
The round heart is that center uniform circular is provided with several fixed strips 7 between the lower yoke surface 12, and adjacent described consolidates
Determine to be provided with air flue 5 between item 7.The upper yoke surface 11 and 12 edge of lower yoke surface are provided with several and the gas
Road 5 cooperates the opaque disk 6 for playing the role of covering.Barrier sheet 31 is provided at the top of the teeth portion 3.The yoke portion 1 and described
3 surface of teeth portion be coated with insulated paint.The yoke portion 1 is made of 3D printing technique.
There is angle between left side bottom and the right side bottom, the angle at 120 ° to 150 °, by left side bottom and
Between the bottom of right side the design of angle can allow yoke portion than existing stator can it is more winding 5% ~ 15% winding.Upper yoke surface is used simultaneously
11 and the design of lower yoke surface 12 can not only allow between yoke surface 11 and lower yoke surface 12 and air flue 5 is set increases whole heat dissipation effect
Rate reduces the heat dissipation problem to arrive after more winding windings, can more increase the length of single-turn coil, winding is played more preferably
Efficiency.In order to reduce whole manufacture difficulty, this punching is integrally formed using 3D printing technique, solves yoke surface 11 under
Fixed problem is assembled between yoke surface 12.
