High-temperature, Electrically-insulating Coating for Magnet Wires

In this SBIR project, Aegis Technology proposes to develop a high-temperature, electrically-insulating coating (HTEIC) for magnet wires used in the magnetic devices of electro-mechanical and power conversion systems. With such a ceramic coating, the insulation properties, thermal stability and mechanical strength of magnet wires can be substantially enhanced as compared with the-state-of-art product, making the magnet wires can work reliably at high temperatures far exceeding than 300 C. The development of HTEIC-based wires will enable the resultant magnetic devices to operate at high temperatures, high power densities and high frequencies, offering the advantages such as high efficiency, small size and light weight. In the Phase I recently accomplished, we have demonstrated a novel magnet wire insulation concept based on a ceramic coating which can be cost-effectively processed by a polymer-based precursor. Based upon the findings and success of Phase I, the proposed Phase II research will focus on technical issues in optimizing the design/processing, characterization and the system integrations. In addition, the benefits of using this HTEIC-based magnet wires will be addressed systematically.
