Koenigsegg announces its first e-motor and EV drive unit

Koenigsegg has unveiled its first e-motor, the Quark, which uses a torque/power-rich balance between radial (power-dense) and axial (torque-dense) flux topology it calls Raxial Flux. The company has also integrated two of them with one of its David inverters, plus planetary gearsets, to create a torque-vectoring EV drive unit it calls the Terrier. The company says a key […]

E-motor materials

The need for low weight and high performance in e-mobility motors is driving a demand for specialist metal alloys and insulating materials that are also thermally conductive. There is a strong focus as well on how they are sourced, particularly with regard to heavy rare earth (HRE) elements. Dysprosium and neodymium for example

Candela C-7 speedboat

Hydrofoiling gives this serial production boat high speed and long endurance. Rory Jackson examines the engineering decisions behind its design. When it comes to designing new kinds of boat hulls that will get as much power and endurance as possible out of battery-electric powertrains, one of the smartest things a maritime architect can do is simply lift the boat out of the water
