What is enameled wire?

Enamelled wire (enamel-insulated insulated wire) is widely used as a coil wire for electric devices such as motors and transformers, and is formed into a cross-sectional shape (for example, round shape or rectangular shape) that matches the application and shape of the coil. An insulating film is formed on the outer layer of the formed metal conductor wire. In recent years, along with miniaturization and higher output of motors for automobiles (for example, alternators, etc.), rectangular enameled wires (cross-sections) that allow coil winding with a higher space factor than round enameled wires (round-shaped enameled wires) Demand for rectangular enameled wire) is increasing. In addition, in order to enable precise coil winding and further increase the space factor, it is required to make the thickness of the enamel wire insulating coating uniform and thin.
