Beer-keg-sized electric motor hits 1,000 hp output on par with Tesla Plaid

Germany\'s Fraunhofer Institute for Integrated Systems and Device Technology unveiled a compact, lightweight electric motor prototype delivering close to 1,000 horsepower, setting a marker in the race to electrify aviation. The 94-kg unit achieves a power density of 8 kW per kg with a small structure about the size of a 12.5-kg gas cylinder. It uses 4x3-phase hairpin windings, direct oil-spray cooling and thin NO15 steel sheets, and includes a four-section redundant safety design for aviation use.
