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.

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.

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!

UL Certificated 220 High Thermal Class Oxidized Film Aluminum Wire and aluminum strip insulated with aluminum oxide film are used in the fields of electronics, missiles, nuclear reactors, aerospace and aircraft industries. The oxide film has high flexibility and is suitable for winding electromagnetic coils of various shapes and sizes. The use of round or rectangular aluminum wires and aluminum strips can save 50% of metal, so it has commercial value. For example, linear motors and medical equipment industries are widely used because of their light weight and low inertia. For rotating equipment, light weight can simplify the dynamic balance, thus reducing the vibration generated by the dynamic balance, thereby improving the sensitivity of the moving coil and its high-frequency response.

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 voltage resistance performance of enameled wire is mainly affected by several factors:
1. The thickness of the insulating layer, not much nonsense;
2. The degree of aging of the insulating layer and the degree of baking affect the withstand voltage.
3. The quality of the insulation layer is mainly the pinhole performance.
