Description
Technical field
The utility model relates to a kind of improved motor stator cores, belong to motor stator technical field.
Background technique
In the prior art, if traditional motor stator core be laminated by dry plate stator punching it is molding, wherein every
Stator punching in its magnetic yoke along protrude out several be directed toward stator punching centers teeth portion, therefore, motor stator core be by
What yoke portion, teeth portion and line embedding groove formed, stator coil is embedded in line embedding groove by way of manual wire embedding, this there is as follows
Technical deficiency:
In motor stator manufacturing process, since embedding notch (gap between adjacent fingers) is directed to stator core wherein
Heart hole, cause manual wire embedding's operation inconvenient, manual wire embedding's work efficiency is low, manual wire embedding's unstable quality, and embedding operation is empty
Between by stator core, its centre bore is limited, influence the working efficiency of manual wire embedding, manual wire embedding is at high cost, leads to motor list
Position product cost is difficult to decrease.
Utility model content
One kind is provided and is changed the technical problem to be solved by the present invention is to overcome above-mentioned the shortcomings of the prior art
Into motor stator core, not only coiling is convenient, work efficiency is high for the motor stator core, and copper factor is high.
In order to solve the above technical problems, the utility model provides the following technical solutions:
A kind of improved motor stator core, including yoke portion with a central hole, are uniformly provided with more in the yoke portion
A main coil inlet wire slot and secondary coil inlet wire slot, each main coil inlet wire slot and each secondary coil inlet wire slot are separated by distribution, improvement
It is to offer main coil inlet wire notch in the groove tops of all main coil inlet wire slots, is opened in the groove top of all secondary coil inlet wire slots
Equipped with secondary coil inlet wire notch, main coil inlet wire slot is in inverted trapezoidal, and secondary coil inlet wire slot is in inverted trapezoidal.
The beneficial effects of the utility model are as follows:
Due to offering main coil inlet wire slot respectively in the groove top of main coil inlet wire slot and the groove top of secondary coil inlet wire slot
Mouth, secondary coil inlet wire notch, thus change conventional motors stator core design structure, realize and carry out outside stator core
Convenient major and minor coil-winding operation has abandoned and has carried out tradition embedding work pattern on stator core, it can be achieved that machine (ratio
Such as by means of flying trident coil winding machine) coiling, machine winding ratio manual wire embedding's skill requirement is low, and coiling quality stability is high, and around
Linear velocity is fast, and unit time coiling yield is high, and coiling coiling expense can be greatly lowered, due to the sky of the coiling outside stator core
Between it is big, interference is few, even more improves the convenience of coiling.
After coiling quality stability improves, the stability of motor is accordingly also improved.
Coiling copper factor is high: due to that can carry out neat winding operation outside stator core, ensure that coil gauge
Homogeneity, and do not influenced by coiling line footpath material thickness, therefore coiling copper factor is high, to improve electric efficiency, this reality
There is certain significance of application with novel.
Detailed description of the invention
The utility model is described in further detail with reference to the accompanying drawing.
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
Refering to Figure 1, below to this by taking outer diameter is 71mm, centre bore is the round motor stator core of 45mm as an example
Utility model is described in detail.
A kind of improved motor stator core is uniformly provided with more including the yoke portion 1 with centre bore 10 in yoke portion 1
A main coil inlet wire slot 2 and secondary coil inlet wire slot 3, main coil inlet wire slot 2 and secondary coil inlet wire slot 3 are separated by distribution, in all masters
The groove top 21 of coil inlet wire slot 2 offers main coil inlet wire notch 22, opens up in the groove top 31 of all secondary coil inlet wire slots 3
There is secondary coil inlet wire notch 32, main coil inlet wire slot 2 is substantially in inverted trapezoidal, and secondary coil inlet wire slot 3 is substantially in inverted trapezoidal.
It is rounded to illustrate yoke portion 1, centre bore 10 is circular hole；Main coil inlet wire slot 2 has 4；Secondary coil inlet wire slot 3 has 4.
The above descriptions are merely preferred embodiments of the present invention, is not to make other forms to the utility model
Limitation, any person skilled in the art should learn the structure change made under the enlightenment of the utility model, all
It is that there is same or similar technical solution with the utility model, still falls within the protection scope of the utility model.
