Inductor made with magnet wire wound around a toroidal core. Magnet wire or enameled wire is a copper or aluminium wire coated with a very thin layer of insulation.It is used in the construction of transformers, inductors, motors, generators, speakers, hard disk head actuators, electromagnets, electric guitar pickups, and other applications that require tight coils of insulated wire.
Until George Jacobs invented a practical enamel for the purpose, cloth was used to insulate magnet wire. This had a number of drawbacks such as, the cloth being too expensive, becoming worn, and bulky. Wire with enamel insulation could be more densely packed, allowing smaller, more efficient motors, coils and other electromagnetic devices.
The wire is then passed through an oven to drive off the solvent and cure the coating. The wire usually is passed through the process several times to achieve the desired coating thickness. The PAI enamel is very thermally stable as well as abrasion and chemical resistant. PAI is often used over polyester wire enamels to achieve higher thermal ...
Jacob's enamel insulation did not wear like cloth did, was less bulky, and more economical to produce. The enamel insulation was especially valuable for producing very thin wire. The company found a market eager for the product - especially the automotive industry, which found the wire indispensable for economical reliable ignition coils.
