Description
Technical field
The present invention 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.
Summary of the invention
The present invention aiming at the shortcomings in the prior art, provides brushless high density wound stator punching, this stator punching energy
The winding of more windings at least 15% with making power more powerful under homalographic, while having good radiator structure, Bu Huirang
Winding overheat.
In order to solve the above-mentioned technical problem, the present invention is addressed by following technical proposals：Brushless high density winding is fixed
Sub- punching, including yoke portion, the yoke portion includes inner circle, and uniform circular is provided with several teeth portion in the inner circle, adjacent
It is provided with winding slot between the teeth portion, it is characterized in that, the winding slot includes two sides and bottom edge, the bottom edge
Including left side bottom and right side bottom, between the left side bottom and the right side bottom have angle, the angle at 120 ° extremely
Between 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 present invention is a kind of novel stator punching, by the redesign to stator punching yoke portion structure, so that stator rushes
The yoke portion of piece is so that the power of this punching is higher in the punching of same size than the winding that existing stator can wind 15% more
Solution winding increases bring heat dissipation problem, this punching has also redesigned lamination structure.Compared to previous integration stamped sheet,
This punching uses catamaran type, had both been divided into yoke surface and lower yoke surface, and had been provided with air flue between upper yoke surface and lower yoke surface, greatly increases
Add heat dissipation performance, while using being manufactured by 3D printing technique, having reduced manufacture difficulty, is suitable for large-scale production.
Compared with prior art, the beneficial effects of the invention are as follows：This stator punching can wind at least 15% winding more, together
Make power more powerful under homalographic, while there is good radiator structure, winding will not be allowed to overheat.
Detailed description of the invention
Fig. 1 is schematic top plan view of the present invention.
Fig. 2 is schematic side view of the present invention.
Specific embodiment
Present invention is further described in 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.
