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 reduces eddy current losses. Hairpin windings improve current density. Also improv
