Abstract
The invention discloses a kind of motor manufacturing methods for preventing motor lead-out wire into paint.It is briefly exactly that the six roots of sensation lead-out wire of motor three-phase windings is merged into three, form a U-shaped exit, after completing dipping lacquer process, cutting among three leads is become into the six roots of sensation again in motor general assembly, in this way, when completely avoiding motor stator winding dip coating process, insulated paint is entered inside lead and is gone.The present invention can prevent the insulated paint in dipping lacquer from entering inside lead-out wire from lead head, it avoids because into poor contact when thering is insulated paint to connect lead-out wire head with copper connecting ear in lead-out wire, the phenomenon that resistance increases and causes burning machine generation, improves the quality of product；The case where lead is hardened is also avoided simultaneously, have the characteristics that easy to operate and saves material.
Description
Technical field
The present invention relates to a kind of motor manufacturing methods, more particularly to a kind of motor manufacturing for preventing motor lead-out wire into paint
Method.
Background technique
In motor manufacturing, the quality of stator manufacture is the key point for determining motor manufacturing quality, and is being embedded the wire
The quality for having winding iron core paint-dipping process afterwards is also to determine motor operation medium temperature to increase low and stator winding whether to generate turn-to-turn short
The important link on road.And be typically all to use vacuum pressure impregnation when there is winding iron core dipping lacquer, motor in this process
Lead-out wire is not allow into paint, and often existing motor manufacturing producer, and lead-out wire is prevented into painting no better measure, special
It is not the lead-out wire of big motor, since electric current is big at runtime for motor, if lead-out wire is difficult into after paint by the paint in lead-out wire
Remove, most of is that lead-out wire lengthens, and cuts away before lead-out wire one big section in wiring, both wasted after cutting away material and
It cannot guarantee that in lead-out wire and do not paint.In addition, also become very hard after lead-out wire dipping lacquer, inconvenience operation.Since pigtail splice has absolutely
It is bad that edge paint contacts the connector of lead-out wire when connected with copper connecting ear, at runtime, since resistance conference is generated heat, slowly
Connector will be blown, to burn out motor.
Referring to Fig.1, existing method after complete line primary connection is that the six roots of sensation draws the end of a thread under motor, and six roots of sensation lead-out wire is connect
On, then end and shaping are wrapped up, enter next procedure-vacuum paint dipping after finishing pressure resistance, interturn test, direct current resistance m easurem ent, has
In dipping lacquer, winding insulated paint while dipping lacquer has been also led into lead-out wire wound stator iron core, so that lead is become very hard, no
Next procedure is facilitated to operate.Problem it is bigger be make draw line resistance increase, be easy to cause motor lead-out wire in use
Joint fever aging is blown, and motor damage is caused.In addition, the prior art also has and the six roots of sensation is drawn the end of a thread lifts dipping lacquer again,
But this method needs lead-out wire hanging height, and lead is made not contact paint, i.e., the workpiece into paint can only be would not allow for be put into top layer, behaviour
It bothers.Also some applies one layer of silica gel oil using by six roots of sensation lead-out wire, but insulated paint still can infilter.
Summary of the invention
In view of the deficiencies of the prior art, the purpose of the invention is to provide a kind of motor for preventing motor lead-out wire into paint
Manufacturing method can prevent the insulated paint in dipping lacquer from entering in lead-out wire from lead head, avoid because into having in lead-out wire
The phenomenon that insulated paint increases pinout connector resistance and makes lead fever aging and cause burning machine generation, improves the matter of product
Amount；The case where lead is hardened is also avoided simultaneously, have the characteristics that easy to operate and saves material.
To achieve the above object, the present invention adopts the following technical scheme that：
A kind of motor manufacturing method preventing motor lead-out wire into paint, which is characterized in that successively include the following steps：
1) it embeds the wire；
2) end shaping is bound；
3) pressure test；
4) lead-out wire is connect:The six roots of sensation lead-out wire of motor three-phase windings is changed to three, three lead-out wires are respectively formed a U
Shape exit；
5) interturn test；
6) D.C. resistance detects；
7) lead-out wire is fixed；
8) vacuum paint dipping；
9) motor general assembly；
10) wiring：By the U-shaped exit severing of three lead-out wires, six pinout connectors are formed, six connectors are connected
It is connected on terminal plate after copper connecting ear.
It, should be by when six heads of three lead-out wires are connect with six head of winding at this time preferably, step 4) connects lead-out wire
Delta connection connection, to be able to carry out measurement when later process interturn test and D.C. resistance test, to guarantee workpiece
Quality.
Preferably, connecing lead-out wire completing step 4):After forming a U-shaped exit, it is also necessary to carry out interturn testing, i.e.,
It tests between coil and coil with the presence or absence of short circuit, additionally it is possible to which whether measuring coil connector connect intact with pigtail splice.
Preferably, the U-shaped exit of three lead-out wires is stacked on top of each other in step 4).
The beneficial effects of the present invention are：
Original six roots of sensation lead-out wire is merged into three by the present invention, forms U-shaped exit, after completing dipping lacquer process,
Cutting among three leads is become into the six roots of sensation again when motor general assembly, in this way, it is entirely avoided during motor stator winding dip coating,
Insulated paint is entered in lead.When motor general assembly, then by six severing of U-shaped exit, formation pinout connectors, it can prevent
In dipping lacquer, insulated paint enters in lead-out wire from lead head, avoid because lead-out wire in into have insulated paint make draw line resistance
The phenomenon that increasing and causing burning machine generation improves the quality of product；The case where lead is hardened is also avoided simultaneously, is had
The characteristics of easy to operate and saving material.
