Beer Keg Powerhouse: The 1,000-HP Electric Motor Redefining Aviation Propulsion Limits
A compact electric motor roughly the size of a 12.5 kg gas cylinder now delivers 1,000 horsepower. Weighing 94 kg, it spins at 21,000 rpm. Power density hits 8 kW per kg. That’s double what typical EV motors achieve, and it beats many advanced aviation units too. Fraunhofer IISB, Germany’s Fraunhofer Institute for Integrated Systems
