Abstract

This project will develop a high-temperature tolerant electrically-insulating coating for magnet wires. The Phase I program will result in a flexible, inorganic coating for copper, nickel, aluminum and their alloy wires that can be wound to produce magnets with superior thermal resistance. Eltron will produce a conformal insulating coating that permits continuous operation at temperature of at least 500 deg. C (932 deg. F), which exceeds current SOA coatings by 100%. According to NEMA, magnet wire is required for the production of 90% of all electricity. As industry attempts to shrink process size and increase output from these devices, their operating temperatures increase and conventional wire insulation tends to fail. High-temperature magnet wire allows for continuous operation under these environments. Few competitors exist that are producing magnet wire capable of functioning in this temperature range.
