The enameled wire has always been a very important industry in the national economy, and with the continuous change and development of the market, the enameled wire industry is constantly adjusting, from the current perspective, the future of the entire enamel wire industry will move towards the future.

Enameled wire motors, electrical appliances, home appliances, communications, electronic information, instrumentation, power tools, automobiles and other industries provide supporting basic material industries. They are the main and key raw materials for electromagnetic windings of motors and electronic instruments. The rapid development of electronic products, etc., has brought a broader application field and market to enameled wires, but at the same time, higher requirements have been put forward for enameled wires, and enameled wires have continued to develop towards a high level and high quality.

The difference between enameled aluminum wire and enameled copper wire of vibration motor: the resistivity of copper wire is 0.017, and the resistivity of aluminum wire is 0.028. The cross-sectional ratio of copper wire and aluminum wire interchange is 0.79:1, and six square copper wires are equivalent to ten square aluminum wires. The diameter of the aluminum wire is thicker than that of the copper wire, and the same aluminum wire of the stator slot will not fit.

Precautions for storage should be well packaged, should not be placed in a high-humidity warehouse, should not be exposed to direct sunlight, and should not be placed near acids, alkalis and organic solvents.

Telephone cable is usually thought of only as a communication medium operating at a normal 48 Vdc level. But telephone cable is regularly used by telephone operating companies to supply power to remote telephony equipment such as: PCM (Pulse Code Modulation) repeaters, FDM (Frequency Division Modulation) repeaters, telegraph and various types of control circuits. The normal talk battery voltage is regularly exceeded in the case of long subscriber loops utilizing loop extenders and on dial long line circuits which operate in the 70 to 100 Vdc range. For these applications, the referenced devices are generally current limited to approximately 150 milliamps. In all such cases, normal telephone industry practice usually limits pair-toground applied voltage to 150 Vdc, and pair-to-pair voltage is usually limited to 300 Vdc.

Another important usage of copper is in manufacturing wire gauges that are largely use in measuring the diameter of wire.
Similarly aluminium is also largely use for electrical application.

Enameled wire coating is mainly used for coating and insulation of enameled wire cores. Since the wire will be subjected to heat, chemical and various mechanical forces in the process of winding coils and embedding wires, the enameled wire paint is required to have good coating properties (that is, uniform coating), and strong paint film adhesion.

Inductive sensors have outstanding advantages such as simple structure, fast dynamic response, and easy non-contact measurement. They are especially suitable for acids, alkalis, chlorides, organic solvents, liquid CO2, ammonia, PVC powder, ash, oil and water. Liquid level measurement such as interface is currently widely used in metallurgy, petroleum, chemical, coal, cement, food and other industries.

Enameled wire is coated with insulating paint on the outside of the bare Aluminium wire, constitute the inside due to the effect of insulating varnish, between the two adjacent wire can bear 200 v ac voltage Q general insulation flow line surface light, soft, can work under the condition of 130 ¡æ continuous.In addition, enameled wire bending also requires 10 times, paint should not fall off, in order to meet the winding when won’t appear the quality problem.

Application of enamel coated magnet wire
Wire for winding used in electrical equipment is generally called magnet wire. Simplyput,”enamel coated magnet wire is used for interchanging electrical energy with magnetic energy”.Magnet wires are broadly divided into enamelled wire (coating insulation), coveredconductor wire (fiber/film insulation), and combinations thereof.

The coating is a process of forming a uniform coating layer of a coating wire to form a uniform coating layer on a metal conductor. This is related to some physical phenomena and painting methods of liquid.

What is called Magnet Wire? The magnetic wire is a copper wire with an enamel (a kind of paint ) coating on it, and used for transformer coils and motor coils. Copper wire is a conductor, like bare copper.

The environmental painted wires of the lacquer formula contains the shortening project development time, saving project funding, and significantly improving the quality of the project.

The motor generally includes a stator and a rotor, with a core and windings on the stator or rotor.
The insulated wire is winded by a certain shape to form a coil. The coil can be a turn or a plurality of turns. A plurality of coils form a group of units and is called a coil group. A combination of a plurality of coils or coil groups constituting one phase or the entire electromagnetic circuit becomes a winding .

Kraft Insulated Copper Stranded Paper Covered Wire refers to the insulation layer of the wire wrapped with cable paper. The paper covered wire insulation has at least 3 layers to wrap the paper tape. When it exceeds 3 feet, the innermost and outermost layers should be covered and wrapped, and the rest can be wrapped around with a gap of no more than 2mm. When the width of the paper tape is 9.5 When mm and above, the gap should not exceed 3mm.

Question: During our production process, we found that one axis of enameled wire is wound around the axial inductance. This axis of enameled wire and other axis of enameled wire are wound on the same magnetic core. The inductance of the enameled wire with this axis is relatively high. We made 1mH inductance, and the enameled wire of the other axis was only 960uH, and the problematic wire of this axis was 1.025mH, and the inductance test frequency was 796kHz. (1) The number of stitches is the same as the number of turns, excluding the slip ring. (2) The 1-meter straight resistance is a bit smaller than that of other shafts. I personally think that the enameled wire contains magnetic substances, but if it contains magnetic substances, the resistivity should be greater, and the DC resistance should be greater. So please help to solve the problem, or have encountered this kind of problem before, please analyze it, thank you in advance!

The infrared spectrum analysis test is based on the standard UL746A, which only confirms the chemical composition of the paint film, establishes the infrared spectrum and retains it. After the enameled wire is certified, samples will be sampled for testing every year during the follow-up inspection service. The infrared spectrum made by the paint film on the sampled sample needs to be compared with the infrared spectrum established on the sample at the time of certification. The two infrared spectrums must be comparable. superior.

An electrical motor is one kind of machine which is used to change the energy from electrical to mechanical. Most of the motors work on the principle of interaction among the electric current as well as the magnetic field within a wire winding. This can generate force in the form of shaft rotation. These motors can be powered with DC or AC sources. The DC sources are batteries whereas the AC sources are inverters, power grids, generators. A generator is mechanically similar to the motor but works in the reverse direction by converting the energy from mechanical to electrical. An electric motor can be built with the rotor, stator, air gap, windings, bearings, & commutator. The classification of motors can be done with considerations like the type of power source, construction, motion output type, and applications. This article discusses what is a motor winding, types, and its calculation.
