Axial flux electric motor specialist YASA is teasing how its next-gen motors will redefine expectations. One of its prototype motors has smashed the power density world record, pulling supercar levels of power from a flat, 29-pound package.

Deriving from electric motor technology that set speed records on land, water and air, the Evolito axial flux machine will bring world-beating levels of power density to the Flying Whales airship, designed to be the largest aircraft in the world.

Donut Lab has premiered its first batch of all-electric motors you can see straight through, ranging from a tiny drone drive to a high-performance hypercar cornerstone the company crowns the world power and torque density king.

Since we looked in on aerospace motor startup H3X in 2020, it's gotten its first round of motors out and signed contracts with major players like the US Air Force and NASA. Now it's working to launch bigger, badder megawatt-class machines.

Every pound counts when you're trying to squeeze range out of an electric aircraft, so when Minneapolis company H3X says it can deliver continuous power at around a third the weight of current motors, it could be huge for clean aviation.

The bulk of this 1,250-horsepower hypercar's prodigious power comes from a tiny 2.88-liter twin turbo engine. Revving at 11,000rpm, it makes nigh-on 950 horsepower, making it the most power-dense production engine in the world at 329 hp per liter.

British company Equipmake has used 3D printing to radically boost power-to-weight figures for its electric motors. The new Ampere motor weighs less than 10 kg (22 lb) and makes a whopping 220 kW (295 hp) while spinning at up to 30,000 rpm.

Researchers working at Siemens say that they have produced a light but powerful prototype electric aircraft motor that could one day help power large passenger airliners. Weighing in at just 50 kg (110 lb) the new motor is claimed to produce about 260 kW (348 hp) at 2,500 RPM.
