How electromagnetic devices work

Electric motors, generators, and transformers operate on the principle of electromagnetic induction. When electric current flows through copper or aluminum coils, it produces magnetic fields. These magnetic fields enable the conversion of kinetic energy into electrical energy, and vice versa. To ensure this process works reliably, each individual wire in the coil must be electrically insulated from the others. Without proper insulation, the wires could short-circuit, disrupting the magnetic fields and leading to equipment malfunction or failure.

ELANTAS provides a portfolio of high performance wire enamels designed to insulate and protect these magnet wires. Our enamel coatings ensure reliable functionality by preventing electrical breakdowns, enhancing thermal stability, and enabling long lasting performance even under demanding operating conditions.

Purpose & function

Designed to insulate, built to endure

ELANTAS wire enamels form the essential insulating layer around copper or aluminum magnet wire prior to winding, preventing electrical failures and ensuring safe operation in electromagnetic devices.
They deliver critical properties, such as:

High thermal resistance
Mechanical strength and abrasion resistance
Flexibility for winding processes
Chemical and moisture resistance
Reliability and long operational lifetime in harsh electrical environments
