Abstract
The present invention proposes a kind of motor inserting-coil process method for improving stator winding copper factor, the internal tooth arrangement of electric machine stator iron is redesigned, internal tooth arrangement is optimized to outer toothing, it is iron core outer circle by stator yoke assembling, by way of external coiling, can be with coil around in a rectangular shape, then by inserting on the stator teeth, then by iron core endoporus it is machined to desired size.The machine of stator core can be greatly improved around copper factor, at the same this kind of technique due to machine around mode replacement's work it is offline, labor productivity can be greatly improved.
Description
Technical field
The present invention relates to technical field of motors, are specially a kind of motor inserting-coil process side for improving stator winding copper factor
Method.
Background technology
With the development of magneto, be widely used in every field, and it is more and more pursue high-performance and
Lighting.From design of electrical motor principle, the copper factor of motor is improved, the electric load of motor can be substantially reduced, so as to effectively
Promotion motor power density.It is traditional offline to be generally divided into the offline two ways of artificial offline and machine.It is manually offline
It is of high cost, the process-cycle is long, has very high requirement to peopleware；Machine is offline to be needed to the suture introducing needle headspace of machine,
Copper factor is low, and space utilization is insufficient, and the power density of motor is low.
The content of the invention
Existing in the prior art to solve the problems, such as, the present invention proposes a kind of motor inserting-coil work for improving stator winding copper factor
Process increases the copper factor of stator winding by the adjustment of inserting-coil process, promotes the labor productivity of motor stator inserting coil.
The technical scheme is that：
A kind of motor inserting-coil process method for improving stator winding copper factor, it is characterised in that：Comprise the following steps：
Step 1：Design is split to inside groove stator core, is divided into stator iron by interface of inside groove stator core tooth bottom
Heart yoke portion and stator core teeth portion, wherein the stator core teeth portion central bore designed is less than the endoporus of inside groove stator core requirement
Size, and fluting design is done in the adjacent between cog root of stator core teeth portion；
Step 2：Stator core yoke portion and stator core teeth portion are processed respectively according to the design of step 1；And in stator core
Teeth portion is inserted in winding coil；
Step 3：Stator core yoke portion and stator core teeth portion are fixedly and coaxially connected；
Step 4：According to the hole size of inside groove stator core requirement, carried out in the adjacent between cog root of stator core teeth portion
Endoporus is cut, and obtains inside groove stator core.
Further preferred scheme, a kind of motor inserting-coil process method for improving stator winding copper factor, feature exist
In：After structured automatical thread-arranging-winding machine coiling winding coil, in each external tooth that winding coil is inserted to stator core teeth portion.
Advantageous effect
The present invention redesigns the internal tooth arrangement of electric machine stator iron, and internal tooth arrangement is optimized to outer toothing, will be fixed
The assembling of sub- yoke portion is iron core outer circle, can be with coil around in a rectangular shape, then by being inserted in stator tooth by way of external coiling
On, then iron core endoporus is machined to desired size.The machine of stator core can be greatly improved around copper factor, at the same this kind of technique by
In with machine around mode replacement's work it is offline, labor productivity can be greatly improved.
The additional aspect and advantage of the present invention will be set forth in part in the description, and will partly become from the following description
It obtains substantially or is recognized by the practice of the present invention.

Specific embodiment
The embodiment of the present invention is described below in detail, the embodiment is exemplary, it is intended to for explaining the present invention, and
It is not considered as limiting the invention.
In the present embodiment, the motor inserting-coil process method for improving stator winding copper factor comprises the following steps：
Step 1：Design is split to inside groove stator core, as shown in Figure 2 using inside groove stator core tooth bottom as interface
It is divided into stator core yoke portion and stator core teeth portion, wherein the stator core teeth portion central bore designed is less than inside groove stator core
It is required that hole size, and do in the adjacent between cog root of stator core teeth portion fluting design, cut convenient for follow-up endoporus.
Step 2：Stator core yoke portion and stator core teeth portion are processed respectively according to the design of step 1；With automatic winding displacement around
Winding coil is turned to structure type as shown in Figure 3 by line machine, then winding coil is inserted into each of stator core teeth portion
In external tooth.
Step 3：Stator core yoke portion and stator core teeth portion are fixedly and coaxially connected, make stator core yoke portion, stator iron
Heart teeth portion is integral with winding coil curing, forms stator structure form shown as shown in Figure 4.
Step 4：According to the hole size of inside groove stator core requirement, carried out in the adjacent between cog root of stator core teeth portion
Endoporus is cut, and forms the inside groove stator core of structure type as shown in Figure 5.
The stator that this kind of technique processes and conventional stator structure are completely the same.This kind of offline mode can be greatly simultaneously
The copper factor of stator winding coil is improved, and traditional hand insertion is substituted by structured automatical thread-arranging-winding machine, is greatly improved
Labor productivity.
Although the embodiment of the present invention has been shown and described above, it is to be understood that above-described embodiment is example
Property, it is impossible to limitation of the present invention is interpreted as, those of ordinary skill in the art are not departing from the principle of the present invention and objective
In the case of above-described embodiment can be changed within the scope of the invention, change, replace and modification.
