Magnet Wire

Magnet wire is a key component in electronic devices, specifically used to create coils or windings in electrical equipment, converting electrical and magnetic energy through the principle of electromagnetic induction.

Major categories include enameled wire (coated with insulating varnish), wrapped wire (fiber-wrapped), enameled wrapped wire (composite insulation), and inorganically insulated wire, meeting varying electrical and mechanical performance requirements.

Standards such as ANSI/NEMA define its dimensions, insulation test methods, and cover both round and rectangular conductor designs.

In applications, it is widely used in general applications such as motors, transformers, and instrumentation to generate electromagnetic effects. In specialized applications such as new energy vehicles, photovoltaic inverters, and LED drivers, magnet wire must withstand high temperatures, vibration, and EMC standards to ensure efficient energy storage and conversion.

For example, in magnetic components such as transformers and inductors, magnet wire serves as the winding core, combined with soft magnetic materials to optimize performance for high frequencies and extreme environments.
