The aluminum core magnet wire, as the name suggests, refers to the magnet wire with aluminum as the core. Also called winding wire. Magnet wire must meet a variety of usage and manufacturing process requirements. The former includes its shape, specifications, can work at high temperature for short and long-term, as well as withstand strong vibration and centrifugal force at high speed in certain occasions, withstand corona and breakdown under high voltage, and resist chemical resistance in special environments. Corrosion, etc.; the latter includes the requirement to withstand stretching, bending and abrasion during winding and inserting, as well as swelling, erosion, etc. during dipping and drying.
Aluminum core magnet wire can be classified according to its basic composition, conductive core and electrical insulating layer. Generally, according to the insulating material and manufacturing method used in the electrical insulating layer, it is divided into aluminum core enameled wire, aluminum core wrapped wire, aluminum core enameled wrapped wire and inorganic insulated wire. The enameled wire of the aluminum core magnet wire is made by coating the outer conductor with the corresponding paint solution, then by solvent evaporation and paint film curing and cooling. Enameled wire can be divided into polyester enameled wire (PEW), polyesterimide enameled wire (EIW), polyamideimide enameled wire (AIW), polyimide enameled wire, polyesterimide/polyamideimide according to the insulating paint used Enameled wire (EIAIW), corona-resistant enameled wire, as well as oil-based 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 enameled wire of the earliest magnet wire is oily enameled wire, which is made of tung oil and the like. The paint film has poor wear resistance and cannot be directly used in the manufacture of motor coils and windings. It needs to be wrapped with cotton yarn when used. Later, the polyvinyl formal enameled wire came out, and its mechanical properties were greatly improved, and it could be directly used in motor windings, and it was called high-strength enameled wire.
