The enameled wire, also known as the winding wire or magnet wire, is a thin wire made of conductive metal material (usually copper or aluminum) with a very thin layer of insulation paint on its surface. This insulation paint is typically made of resin materials such as polyester, polyimide, polyamide, or polyetherimide, used for electrical insulation and mechanical protection. The enameled wire is widely used in electronic and electrical devices, often seen in various coils, such as motors, transformers, electromagnets, speakers, hard disk drive motors, and other types of inductive components. Due to the presence of insulation paint, even if the coil is tightly wound, there will be no short circuit between adjacent coils. The enameled wire is classified into different types based on the insulation paint's heat resistance and performance, such as 130, 155, 180, 200, and 220 levels, which represent the highest temperature (in Celsius) that the coil can withstand in continuous operation. When used, in order to make the enameled wire's conductive endpoints solderable or connectable to other conductive components, the insulation paint usually needs to be removed at the terminal ends, which can be achieved through mechanical grinding, chemical stripping, heat burning, or using a special paint stripper.
