The enameled wire paint coats up to 30 layers of copper and aluminum wires to provide electrical insulation and help avoid short circuits in the coil. Such enameled wire paint must also have excellent chemical resistance and high temperature resistance, must have excellent adhesion with copper or aluminum wires, and also have excellent mechanical stability.
In some cases, such as for motors driven by frequency converters, a suitable insulation layer should be able to resist partial discharges that may cause short circuits and malfunctions in the engine.

Wire enamel insulating varnish is a kind of paint that can produce a good insulation layer between the wires in the winding. It is mainly used for the outer layer of bare copper wire, alloy wire and glass wire covered wire of various wire diameters to improve and stabilize the performance of enameled wire.

Correspondence table of enameled wire diameter and resistance value
The resistivity of the copper wire ρ= 0.0172, the aluminum wire ρ = 0.0283, the wire resistance calculation formula:
R=ρ×L/S
(L = wire length, unit: meter, S = wire cross section, unit: mm^2)

The current mainly passes along the copper-clad aluminum wire on the surface of the wire, which is called the skin effect. The higher the frequency, the more obvious it is. The copper-clad aluminum wire uses this feature to save material. But its resistivity is slightly higher than that of pure copper wire, and the resistivity is also different with the thickness of the copper clad.

1. Cutting
The enameled wire is composed of a conductor and an insulator, and the hardness of the two parts is very soft, so it can be cut by using a TabCUT-200 precision cutting machine with a general SiC cutting chip. Since the insulator is coated on the conductor, and its hardness and ductility are quite different, and the insulating layer has a certain degree of peeling, it is better to use some soft materials such as tin foil, rubber, etc. to wrap the cutting part when cutting. Up to prevent the insulation layer at the fracture from peeling off after cutting.

Enameled wire is a main type of winding wire. It consists of a conductor and an insulating layer. After the bare wire is softened by annealing, it is painted and baked many times. However, it is not easy to produce products that not only meet the requirements of the standard, but also meet the requirements of customers. It is affected by the quality of raw materials, process parameters, production equipment, environment and other factors. Therefore, the quality characteristics of various enameled wires are different, but they all have Mechanical properties, chemical properties, electrical properties, and thermal properties are four major properties.

Aluminum bare magnet wire (Anodized Bare Aluminium wire) belongs to the special electromagnetic wire and the insulation layer is the aluminum oxide .Because of no thermal aging phenomenon, it can be used as insulation level of class 220.
The insulation layer of such product is thin, high temperature resistance and insulation performance stability,which is the best choice for low voltage winding wires with producing high temperature, poor environment, heat dissipation difficulty and so on. It can widely be used in electromagnetic industries at home and abroad.

The enamel wire is a wire having an insulating layer, which is a transformation of electromagnetic energy in a winding form, also known as a winding wire.

Round Enameled Wire is used for transformer coil winding and motor winding, also called electric motor winding wire. And to Measure The Specifications Of Round Enameled Wire is important, include the conductor diameter and insulation diameter.

Principle: Water molecule (HHO) decomposes water into oxygen and hydrogen through electrolysis. Hydrogen is combustible. Oxygen supports combustion. These two gases are ignited to form a hydrogen-oxygen flame. In layman’s terms, “water turns into fire”

Copper paint package wire production process principle

Copper lacquer wires are coated with respective lacquer solutions, and then cured by solvent volatilization and paint film.The earliest enamel wire is oily painted wire, made from tung oil.Its paint film is abrasion resistant, and cannot be used directly to make motor coils and windings, and the cotton yarn can be added to the layer.Later, polyethylene glycol formaldehyde lacquer wire came out, and its mechanical properties were greatly improved, which can be used directly for motor windings, which is called high-strength enameled wire.

The samples for the dielectric strength test are also twisted pairs, and the number is 5 pairs. During the test, the voltage was applied at a boosting rate of 500V/S until breakdown, and the voltage at the time of breakdown was recorded. The requirements for dielectric strength in the NEMA MW1000 standard will vary according to different wire diameters, different paint film thicknesses, and different enameled wire types.

To weld the lead aluminum enameled wire, it is necessary to remove the paint (there are very few household electric fans with very low requirements, and the ballast manufacturer does not remove the paint). The paint removal methods are listed below.
(1) It can be scraped with a blade,
(2) It can be peeled with a centrifugal knife,
(3) The paint can also be rubbed off with a grinding wheel,
(4) Of course paint remover is also available,
(5) You can also use high-temperature tin to burn the paint,
(6) Some people burn with fire
(7) Of course you can also use paint remover to remove paint

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.

Insulating paint is composed of three parts of paint base (natural or synthetic resin, asphalt, drying oil, fiber paper and its composites, etc.), solvent or diluent, and auxiliary materials (drier, pigment, emulsifier, antifungal agent, etc.) . According to the purpose, it can be divided into three types: dipping paint, covering paint and adhesive paint.

Polyimide Kapton Covered Enameled Aluminum Wire Strip is a multi-layer polyimide & fluoropolymer dispersion-coated film. The fluoropolymer coating functions as a heat-fusible layer for bonding to magnet wire conductors. It has superior scrape abrasion resistance and exhibits lower frictional properties than wire insulated with other commonly used polyimide materials. Polyimide film aluminum wire is ideal for demanding magnet wire applications and for difficult-to-wind motors.

enameled aluminum wire is composed of aluminum conductor and insulation materials, which is insulated with a thin film or coating and creates a magnetic field when the wire is would in a coil and power is applied. Aluminum Conductor is main type of enameled wire.

The selection criterion of the electromagnetic wire is not considered for resistance, as the problem of resistance and fever can be done by selecting the same cross-sectional wire, it is the main consideration of the thick wire or the thin wire is mainly considered Operability.
