Electrical Insulation Materials in Hybrid Aerospace
AIR6674
This draft AIR highlights the current state of the art in materials for electrical machine windings and related test standards. This is intended as a discussion document to highlight gaps in the current standards and the requirements for future aerospace test methods for electrical insulation materials operating at altitude & at high frequencies.
Rationale: This report outlines the key insulating materials used for commonly used twisted wire samples and the materials issues that are apparent for the said insulating materials. The report also includes information on current standards that are used in creating, testing and lifetime prediction of these precursors in electrical machine testing
