Insulation Development

Overview

• Although the key role for insulation in electrical machines is electrical isolation, thermal conductivity is equally impactful in electric machine design. Trapped heat increases the electrical resistance of conductors, resulting in lost efficiency, greater fuel consumption, and greater overall thermal management burden.
• Two-dimensional ceramic particles in the microscales and nanoscales are the foundation of many state-of-the-art insulation solutions, and provide many promising approaches for further development. Recent work at NASA Glenn in separating hexagonal boron nitride (hBN) into nanosheets, thus exploring the use of established compounds in a new way.
