The winding is the most important part of the motor, and the choice of Enameled Copper/Aluminum Wire For Motor is also very important

The space factors of magnet wires are compared in the right figure. The space factors of enamelled wires are superior to those of other wires for winding, as are their electrical properties. However, more careful examination must be made of the following properties as compared with other wires.

After the product is manufactured, whether its appearance, size and performance meet the requirements of the technical standards of the product and the technical agreement of the user must be judged by the inspection beam and measured; the test shall be compared with the technical standard of the product or the technical agreement of the user and meet the requirements If it is qualified, otherwise, it is unqualified. Passing the inspection can reflect the stability of the enameled wire product quality, the material and the rationality of the process. Therefore, the quality inspection has the function of checking, preventing and identifying.

Paper-covered Aluminium magnet wire deliver excellent performance when used with oil such as transformer oil. A paper with a small hygroscopicity, mechanical strength, good permeability for oil, and high dielectric strength should be selected.

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.

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.

In recent years, the price of electrolytic copper has continued to rise, which has brought a huge impact to the production of related copper wire raw materials and enameled wire suppliers. The use of copper-clad aluminum enameled wire has been proved by users to replace pure copper enameled wire, thus providing a huge business opportunity and a broad market for the development of my country’s enameled wire industry. The new type of Enameled Copper Coated Aluminum Magnet Wire For Voice Winding using copper clad aluminum material as the inner conductor has characteristics between copper and aluminum, combining the excellent conductivity of copper and the light weight of aluminum.

Flat enameled wire is a type of enameled wire. It is a winding wire made of oxygen-free copper rods or electrical aluminum rods that are drawn, extruded or rolled by a certain specification die, and then coated with insulating paint for many times. The thickness is from 0.025mm To 2mm, the width is generally less than 5mm, and its aspect ratio ranges from 2:1 to 50:1. Flat enameled wire has a wide range of uses, especially in the windings of various electrical equipment such as telecommunication equipment, transformers, motors and generators.

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.

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.
