There are two ways. The first step is a bit complicated.

But it should be easy to do ~ ~ ~ first. Fold the red line in half.

Click the ring where you need to wrap the red line. So one end of the red line is broken.

One end is connected together. Second.

Take a thread from the broken end and make a summary. Start winding the knotted thread around one end of the connection.

Go around ~ ~ and wind it tighter ~ ~ that is to say, after you wind the wire, one end of it is a connection line. There is only one line at one end.

Third. After winding the wire.

Thread your twisted thread into the connected end. Then pull the remaining thread at the other end.

You will find that. The connection end shrinks.

Finally, pull your winding thread into your winding circle. . Tighten.

Cut the remaining thread with scissors. It doesn't matter.

The second largest is "flat knot", which is more durable.

2. How to wind the motor?

Technical specifications for windings. Technical specifications for stator coil windings

1. Scope of application

This specification applies to stator windings and rotor windings of single-phase and three-phase asynchronous motors.

2. Materials

2. 1 electromagnetic wire: enamelled copper round wire. 2.2 cotton rope.

3 Equipment and tools

3. 1 The winding machine with counter shall be equipped with equipment coil bobbin, wire clamping plate lined with felt, tensioning device and other facilities. 3.2 Winding die.

3.3 Common winding tools: wire cutters, scissors, wrenches and calipers.

3.4 Inspection tools and instruments: micrometer and dial indicator. 3.5 station equipment.

4. Process preparation

4. 1 Prepare the technical documents and materials needed for coil winding and the tools needed for winding.

4.2 Check the wire diameter, and install the coil on the wire frame (see the attached table for parameters of common enameled copper round wires).

4.3 Check the size of the wire mould and install it on the spindle of the winding machine.

4.4 Debugging: Adjust the winding speed, check the counter and set it to zero.

4.5 Fix the end of the enameled copper round wire on the main shaft of the winding machine, and then tighten the enameled copper round wire to a proper tightness (it is advisable to straighten the enameled wire on the principle of not thinning the enameled wire and damaging the insulation).

5. Process flow

5. 1 Leave an appropriate length at the beginning of the conductor as required and fix it on the pin made of winding model.

5.2 Start the winding machine and wind the first coil. The wires are arranged neatly and tightly from left to right in the groove without crossing. Stop the machine when the counter reaches the specified number of revolutions.

5.3 Leave the connecting wire and wind the remaining coils in the same way.

5.4 Leave terminal leads according to the specified length, and cut off the leads.

5.5 Remove the winding die, take out the coils one by one, and help tie the upper and lower ends of the coils.

5.6 The winding of the whole motor shall be completed according to 5. 1~5.5, tied up after being checked by the tachometer, and neatly placed on the station where the coil is stored.

6. Quality inspection

6. 1 The first piece of each batch of wound coils must be inspected according to relevant technical documents before it can be put into production.

6.2 In normal production, the following items should be checked.

6.2. 1 Check the number of turns of each coil with a turn tester to meet the requirements of the drawings.

6.2. 1 The number of conductor joints in each coil shall not exceed one, two in each phase coil and four in each motor. The joint must be at the hypotenuse of the end, and the binding shall comply with the provisions of Article 7. 1.

6.2.3 The coils in the instrument of the workstation shall be arranged neatly, and the insulation shall not be damaged.

7. Technical safety and preventive measures

7. 1 If insufficient wire length or broken wire is found in the winding, welding is allowed, but the following provisions must be observed.

7. 1. 1 The joint position is only allowed at the hypotenuse of the coil end.

7. 1.2 Welding shall ensure good contact, sufficient mechanical strength and smooth surface.

7. 1.3 The length of the overlapping part of the insulation sleeve at the joint relative to the conductor insulation should be greater than15 mm.

7.2 When winding wires, observe the wires carefully. If there is insulation damage, it shall be implemented according to 7.1.1~ 7.1.3, but there shall be no more than one coil and no more than two coils per phase.

7.3 The wound coils shall be neatly placed on a clean workbench, and the stacking height shall not exceed 0.5m, and there shall be no bending deformation.

7.4 Check the wire gauge every time the wire is changed, and use it only after it is qualified.

7.5 The winding machine should have reliable grounding protection device.

7.6 When working, female workers must wear working hats.

3. Schematic diagram of ring winding method What should I do if the ring is big?

1, flat knot method. The flat knot method should first prepare a tough rope, bypass the ring in the shape of "you", follow the steps of winding diagram, and then officially start after knotting (pay attention to tying the knot on the left or back side). Next, tie the second knot, the direction of the knot is opposite to the previous one, and continue to tie the knot until the extra thread is cut off. Note that the rope must be tightened during the whole process, otherwise it will come loose easily.

2. The second method is to adopt the circular encircling method, which can reduce the squeezing of fingers. First, prepare a winding, bend it and then repeatedly wind it on the ring with the other end. As shown in the winding diagram, after continuous winding, it goes out at the back bend, and the other side tightens the winding and cuts off the ends on both sides.

4. How to weave a bracelet with red rope?

It's a little complicated to say suddenly. But it should be very simple to do ~ ~ ~

First of all. Fold the red line in half. Click the ring where you need to wrap the red line. So one end of the red line is broken. One end is connected together.

Second. Take a thread from the broken end and make a summary. Start winding the knotted thread around one end of the connection. Tuan Tuan ~ ~ Wrap it tight ~ ~ ~

In other words, after you wind the thread, one end is a connected thread. There is only one line at one end. .

Third. After winding the wire. Thread your twisted thread into the connected end. Then pull the remaining thread at the other end. You will find that. The connection end shrinks. Finally, pull your winding thread into your winding circle. . Tighten. Cut the remaining thread with scissors. It doesn't matter.
