aluminium Magnet wire can be classified according to its basic composition, conductive core and electrical insulation layer. Usually according to the insulating material and manufacturing method used for the electrical insulation layer, it is divided into aluminum core enameled wire, aluminum core wound wire, aluminum core enameled wire and inorganic insulated wire.
The enameled wire of the aluminum core magnet wire: coated with the corresponding lacquer solution on the outside of the conductor, and then made by volatilizing the solvent and solidifying and cooling the lacquer film. The enameled wire can be divided into polyester enameled wire, polyesterimide enameled wire, polyamideimide enameled wire, polyimide enameled wire, polyesterimide/polyamideimide enameled wire, corona resistant enameled wire, and oily Paint, acetal paint, polyurethane enameled wire, etc. Sometimes it is also classified according to the particularity of its use, such as self-adhesive enameled wire, refrigerant resistant enameled wire, etc.
The earliest magnet wire enameled wire is oily enameled wire, made of tung oil. The paint film has poor abrasion resistance and cannot be directly used to make motor coils and windings. It needs to be covered with cotton yarn when used. Later, polyvinyl formal enameled wire came out, and its mechanical properties were greatly improved. It can be directly used in motor windings and is called high-strength enameled wire.
