Magnet wire is one of the core materials in manufacturing heavy electric products, home appliances, and automobile parts. It is usually wound in the form of a coil inside the electric device and converts electric energy into kinetic energy or vice versa, as classified into PEW, AIW, EI-AIW, SL-EI-AIW, SB-EI-AIW, etc. according to the characteristics.
Enamelled wire, also referred to as enamel wire, magnet wire, winding wire, magnetic wire - a type of winding wire, usually made from copper or aluminium, insulated by a type of cured resin called enamel, and used for making windings and coils.
Enamelled copper wire with a round cross-section is widely used in windings of small and medium size electric motors and transformers, as well as other electromagnetic devices such as sensors and actuators.
Litz wire is typically made from enamelled copper wire.
Enamelled wire (0.43 mm outer and 0.375 mm copper diameter, enamel thickness 0.0275 mm) under a microscope: left - cut end with visible copper core (pink metal) and a layer of enamel (darker coating), right - crack in the enamel caused by bending the wire over too small a radius (bare copper visible underneath)
