2 days ago · HEMM has a target performance of 16 kW/kg, 99% efficiency, and will have 3 times lower losses and weight than current aircraft motors and generators. The HEMM technology can be integrated with a typical aircraft cooling system and can be applied to a range of aircraft types that require megawatt-level electrical power. New technologies must be ...

Dec 20, 2022 · The 1.4 MW High Efficiency Megawatt Motor (HEMM) is being designed to meet the needs of electrified aircraft propulsion. HEMM has a target performance of 16 kW/kg, 99% efficiency, and will have 3x lower losses and weight than current aircraft motors and generators.

NASA High Efficiency Megawatt Motor (HEMM) Power / Performance • HEMM is a 1.4MW electric machine with a stretch performance goal of 16 kW/kg (ratio to EM mass) and efficiency of >98% Machine Features • partially superconducting (rotor superconducting, stator normal conductors) • synchronous wound field machine that can operate as a motor

The key objective of HEMM is to establish a motor technology which simultaneously attains high specific power (>16kW/kg ratio to electromagnetic weight) and high efficiency (>98%) by judicious application of high temperature superconducting wire and integrated thermal management.

NASA’s High Efficiency Megawatt Motor (HEMM) is being developed to achieve the performance needed by single aisle class electrified aircraft. It is a 1.4 MW electric machine designed as a generator for NASA’s STARC-ABL concept vehicle.
