Abstract

The invention discloses a motor production method of preventing paint from entering motor leading-out wires. Six leading-out wires of a motor three-phase winding are combined into three leading-out wires, and a U-shaped leading-out end is formed. After a painting process is completed, the three leading-out wires are cut out from the middle parts to form the six leading-out wires during the general assembly of the motor. Insulation paint is completely prevented from entering inner sides of leads during a motor stator winding painting process. The insulation paint is prevented from entering the inner sides of the leading-out wires through the head parts of the leads during the painting process, and a burnout phenomenon caused by weak contact and increased resistance caused by the insulation paint entering the leading-out wires during the connection between the head parts of the leading-out wires and copper connecting lugs is prevented, and therefore product quality is improved; and at the same time, the hardening conditions of the leads are prevented, and operation is simple, and materials are saved.

Description

A kind of motor manufacturing method preventing motor lead-out wire from entering paint

Technical field

The present invention relates to a kind of motor manufacturing method, particularly relate to a kind of motor manufacturing preventing motor lead-out wire from entering paint Method.

Background technology

In motor manufacturing, the quality of stator manufacture is the key point determining motor manufacturing quality, and at rule After have the quality of winding iron core paint-dipping process be also determine motor run in temperature rise height and stator winding whether to produce turn-to-turn short The important step on road.And vacuum pressure impregnation is typically all used when there being winding iron core dipping lacquer, motor in this process Lead-out wire is not allow into paint, and the most existing motor manufacturing producer, lead-out wire is prevented not having more preferable measure into paint, special It not the lead-out wire of big motor, owing to motor operationally electric current is big, if after lead-out wire enters paint, be difficult to the paint in lead-out wire Removing, great majority are to be lengthened by lead-out wire, before lead-out wire one big section are cut away when wiring, both wasted material after cutting away and Do not paint in cannot guarantee that lead-out wire.In addition, also become very hard after lead-out wire dipping lacquer, be awkward.Owing to pigtail splice has absolutely Edge paint makes the joint of lead-out wire contact bad when connected with copper connecting ear, operationally, owing to resistance conference is generated heat, slowly Joint will be blown, thus burn out motor.

With reference to Fig. 1, existing method is that the six roots of sensation draws the end of a thread after complete line primary connection under motor, is all connect by six roots of sensation lead-out wire On, then wrap up end shaping, enter next procedure-vacuum paint dipping after finishing pressure, interturn test, direct current resistance m easurem ent, have Wound stator is unshakable in one's determination when dipping lacquer, and winding during insullac has also led into lead-out wire while dipping lacquer, makes lead-in wire become very hard, no Next procedure is facilitated to operate.What problem was bigger is to make lead-out wire resistance increase, and easily causes motor in use lead-out wire Joint heating is aging blows, and causes motor damage.It addition, 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 is hung height, make lead-in wire not contact paint, i.e. can only would not allow for putting into top layer into the workpiece of paint, behaviour Bother.Six roots of sensation lead-out wire is coated with one layer of silica gel oil by the employing also having, but insullac still can infilter.

Summary of the invention

For the deficiencies in the prior art, the invention aims to provide a kind of motor preventing motor lead-out wire from entering paint Manufacture method, it is possible to prevent when dipping lacquer insullac to enter lead-out wire from lead-in wire head, it is to avoid because entering to have in lead-out wire Insullac makes pinout connector resistance increase and makes lead-in wire heating aging and cause the phenomenon of burning machine to occur, and improves the matter of product Amount；It also avoid the hardening situation of lead-in wire to occur simultaneously, there is feature that is easy to operate and that save material.

For achieving the above object, the present invention adopts the following technical scheme that

A kind of motor manufacturing method preventing motor lead-out wire from entering paint, it is characterised in that comprise the following steps successively:

1) rule；

2) end shaping colligation；

3) pressure test；

4) connecing lead-out wire: the six roots of sensation lead-out wire of motor three-phase windings is changed to three, three lead-out wires form a U respectively Shape exit；

5) interturn test；

6) direct current generator detection；

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, form six pinout connectors, six joints are connected It is connected on patch panel after copper connecting ear.

As preferably, step 4) connect lead-out wire, when now six heads of three lead-out wires are connected with winding six head, should be by Delta connection connects, in order to can measure when later process interturn test and D.C. resistance test, in order to ensure workpiece Quality.

As preferably, complete step 4) connect lead-out wire: after forming a U-shaped exit, in addition it is also necessary to carry out interturn testing, i.e. Whether short circuit is there is, additionally it is possible to measuring coil joint is connected the most intact with pigtail splice between test coil and coil.

As preferably, step 4) in, the U-shaped exit of described three lead-out wires is superposed.

The beneficial effects of the present invention is:

Original six roots of sensation lead-out wire is merged into three by the present invention, forms U-shaped exit, after completing dipping lacquer operation, Become cut off in the middle of three lead-in wires into the six roots of sensation, so again, it is entirely avoided during motor stator winding dip coating during motor general assembly, Insullac is entered in lead-in wire.During motor general assembly, then by U-shaped exit severing, six pinout connectors of formation, it is possible to prevent When dipping lacquer, insullac enters lead-out wire from lead-in wire head, it is to avoid because entering to have the insullac make lead-out wire resistance in lead-out wire Increase and cause the phenomenon of burning machine to occur, improve the quality of product；It also avoid the hardening situation of lead-in wire to occur simultaneously, have The easy to operate feature with saving material.
