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

Focus on...

Sealing

Seals and sealants perform a host of unsung but vital functions. Peter Donaldson explains the different types, their uses and the materials they are made from

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

New motor architecture could be a game-changer

At a time when EV manufacturers are eager for efficiency gains of 2-3% in their powertrains, any new technology capable of providing 10% or more would transform the state of competition among vehicle OEMs (writes Rory Jackson). With an eye towards enabling that, US company ePropelled has developed and patented a new type of electric […]

Riversimple Rasa

Rather than go all-out on the technology, this EV has been conceived with reusable components – and the circular economy – in mind. Rory Jackson reports. End-to-end sustainability is a troublesome target for EV engineers to track. Reducing vehicle emissions at the point of use is easy enough, but reducing the emissions...

Skateboard platforms

Against the backdrop of a boom in skateboard platforms for EV designs, Nick Flaherty looks at the approaches taken by some of their suppliers. Changing the wheelbase of a traditional car or truck design by 6 or 7 in creates a ripple effect whereby half the transmission shaft has to be redesigned, changing the centre of gravity and the requirements for the suspension. That means a whole new vehicle design is needed...

Andrew Cross

Integral Powertrain’s CTO tells Rory Jackson how he has come to lead the company’s development of high performance consumer EV drives. One of Andrew Cross’ most prominent early memories is the engineering company his father owned and ran, designing and manufacturing polymer parts, and developing much of his own production systems and tooling...
