What Is Magnet Wire?

Magnet wire is wire which can be specifically created to construct coils which will make electromagnetic fields when energized The energizing can be achieved by AC or ELECTRICITY power sources.

Construction

Magnet wire consists of either annealed and electrolytically refined insulated cooper wire or of aluminum is actually sold in varying dimensions or gauges. The thickness the wire, the bigger the gauge, and thus the minus the resistance to current trade. Features The coating may also be enamel and may be achieved from combinations of materials something such as polyester, polyvinyl, polyurethane which polyamide. Either single or double coating can be utilized, though single coating usage is much more typical.

Function

Magnet wire can be used in making components such as transformers, potentiometers, motors, relays together with solenoids. It is positioned in devices such as electric guitars, telephones, speakers, hard keeps, automobiles and headphones.

Fun Fact

During Battle II, magnet wire was to build millions of transformers within the Allies, thousands of miles of telephone wire for you Army Signal Corps, additionally harnesses for B-24 bombers.

Tips

For projects where may building devices that need to produce electromagnetic fields, including speakers, thermocouples, antennas also called electromagnets, it is more efficient to work with magnet wire. In certain cases, you may be needing to remove the insulation if an individual optimal effect .

Mechanical Property Requirement of Enameled Wire

When wire wound into a coil and embedding process, between enameled wire, enameled wire and fixtures will rub against each other. So the enameled wire will suffer from bending, stretching or compressing. Thus enameled film is required to have good abrasion resistance, scratch resistance and good adhesion to the conductor.

For ease of manufacturing and processing, enameled wire is required good softness, elasticity and bending performance, so easily deformed coil molding. Modern high-speed automatic wire winding machines also require a smooth surface, low coefficient of friction, and special purpose wire and requires a greater coefficient of friction. When the motor is running, winding will suffer from stress by shock, vibration, centrifugal force and thermal expansion. So enameled wire should have a tensile strength.

Some notes to electromagnetic coil

Electromagnetic coil is a fine of components.Improper use can easily cause damage its electromagnetic coil. There has a great impact on the overall operation of the device. When we use,there are many places that need to pay attention. Here we are in the course of all of its points to note reminder for everyone:

1. When we use, it must sure that the voltage should never exceed the voltage index which coils can withstand, otherwise the solenoid would be burned, causing serious impact on the overall mechanical operation.

2. The thickness of the length of the solenoid coil are different and there is no absolute right perfect layout. People often choose according to their own needs.

3. If the unit is required to work long hours in factories, the temperature of working pressure of our electromagnetic coil temperature will rise. At this time, people should carry out protective measures according to their specific circumstances.

4. In our time, we can make that the solenoid coil is processed according to the conditions. Do not make the electromagnetic coil performance in disorder.

Only when we ensure the safety of the use and reasonable diligence to protect and ensure, the use of magnet wire will be under normal conditions of use. Our electromagnetic coil can create greater efficiency for long-term services .

Modified Polyester-imide enameled wire

Modified Polyester-imide is produced by insulating the conductor with a single coat of a solder-strippable modified polyester resin. Physical properties are adequate for most coil applications. More severe winding requirements such as in-slot stator windings are not recommended without thorough evaluation. This film may be readily stripped from the conductor by immersing in an 850° - 950°F solder pot; care must be exercised in preventing the film from over-cutting due to poor immersion techniques.

Awg magnet wire

Magnet wire insulating films use (in order of increasing temperature range) polyurethane, polyamide, polyester, polyeseter-polyimide, polyamide-polyimide (or amide-imide), and polyimide. Polyimide insulated magnet wire is capable of operation at up to 250°C. The insulation of thicer square or rectangular magnet wire is often augmented by wrapping it with a high-temperature polyimide or fiberglass tape, and completed windings are often vacuum impregnated with an insulating varnish to improve insulation strength and long-term reliability of the winding.

Correct production process of enameled wire

The quality of enameled wire depends although to a large extent depends on the objective circumstances paint, wire and other raw materials and machinery and equipment quality. It should do many thing that can produce high-quality enameled wire. It should take care of baking, annealing, speed and other issues in the operation and be aware of their mutual relations . At the same time, if people have not mastered technique, not do a good job of work and stop tour finishing work, the process does not improve health. Even if the objective conditions better, it do not produce high-quality enameled wire. So we must take care of enameled wire production process seriously in order to produce high-quality enameled wire products. Now let our Zhengzhou LP Industry Co., Ltd , a professional manufacturers to introduce the correct method of operation of enameled wire.

1, Paint charter before driving should be open fan to make the furnace air circulation to slow. Ignition temperature of the furnace and the catalytic domain with an electric preheating, the temperature of the catalytic zone reaches a predetermined catalyst.

2, The film should be measured once an hour. Before measuring, micrometer card correction keep zero.

3, Check all moving parts properly. Pay attention to put a spool of elastic to prevent rolling head, and drawing a fine break and diameter.

4, During enameled wire production operations, it should also pay attention to the explosion and fire problems, mainly inside the furnace fire phenomenon.
