Thin film motor boost

A new generation of thermoplastic is replacing aramid papers and enamel coatings in motors. The advanced thermoplastic, now being adopted using existing production equipment in a new generation of motors, is showing a reduction in weight and an increase in efficiency through improved thermal management...

Why axial flux motors are opening up new possibilities for off-highway electrification

Increasingly close powertrain integration is well established in the passenger car sector, but for off-highway, construction, and commercial vehicles, the path to electrification presents a unique set of challenges, writes Peter Donaldson.

Jurij Kern redefines the car with in‑wheel motors and next‑gen EV architecture

urij Kern has been on a mission with Elaphe for his entire career – and his work could soon revolutionise the architecture of the automobile. Will Gray finds out more Ever since the dawn of the time of the automobile, it has always had a relatively familiar look. However, the in-wheel motor revolution could be about to change all that – and Jurij Kern has been at the centre of this technology’s development ever since he graduated from university.

Improving magnetic performance in EV motors

Researchers in South Korea have developed a process for creating permanent magnets that reduces the need for heavy rare earth elements, writes Nick Flaherty. The process significantly advances the diffusion technology, which is essential for improving magnetic performance, and creates new possibilities for applying high-efficiency magnets in EV motors.

Porsche Cayenne Electric debuts with 850 kW powertrain and next‑gen 113 kWh battery system

Porsche has begun series production of the Cayenne Electric, marking the brand's entry into the premium electric SUV segment with in-house battery manufacturing capability in Slovakia. The Turbo variant delivers up to 850 kW and is built on a flexible line alongside combustion and hybrid Cayenne models at the Volkswagen Group plant in Bratislava, so the EV effectively becomes another derivative in an already high-volume programme rather than a standalone product.
