750 kW, 94 kg delivering 8 kW/kg Hairpin windings are redefining motor design. Fraunhofer IISB’s aircraft motor proves it. I was reading this Fraunhofer IISB 's Hybrid-electric regional aircraft motor. It built something impressive. The motor of 750 kW, 94 kg Delivering 8 kW/kg Typical EV motors: ~2–4 kW/kg Speed reaches 21,000 rpm. Torque is 350 Nm. Cooling uses direct oil spray. Rated at 65°C coolant. They used NO15 electrical steel. Thickness is just 0.15 mm. This red

I was studying aerospace powertrains recently. Electric propulsion feels closer than ever. ZeroAvia’s 600kW engine proves it’s real. FAA cleared ZeroAvia’s 600kW electric engine system. Motor is a direct-drive, 2200 rpm shaft. Direct-drive means no gearbox losses. Controller: manages speed and torque precisely. Inverter: converts DC to AC power. Power is fuel ccell based 600 kW continuous output.⚡ Airbus explores 100-seat hydrogen aircraft. Hydrogen aviation sees strong
