Magna has unveiled its next generation 800 V eDrive solution, which it says offers improved efficiency, power-to-weight ratio and torque density. Magna claims that its 75 kg next-generation eDrive is lighter, 20% shorter in height and faster than its prior generation eDrive, providing a longer driving range. Rotating the eDrive 90° around the drive axis… Read more »

Altilium works to transform mine tailings into valuable EV battery materials
UK-based clean technology group Altilium has secured over £700,000 in UK government funding for two collaborative research projects focused on the recovery of copper and rare earth elements (REE) from mine waste. Building on previous work to recover lithium and other battery materials from end-of-life EV batteries, Altilium is partnering with CPI and the Camborne… Read more »
Renault and Valeo develop new electric motor for EVs
Carmaker Renault and equipment manufacturer Valeo in France are collaborating to create a new electric motor generation. E7A, the third generation of this motor, is in the prototype stage and will debut in 2027. Renault is contributing the rotor and Valeo the stator, and both companies are providing technology development and production expertise. Renault plans… Read more »
Optimizing eMotors for Range, Cost and Sustainability
Sustainability is one of the fundamental features in electric motors. Whether it is a traditional PSM motor or advanced magnet free motor with powered rotor coils, Schaeffler focuses on optimal use of both the space and materials to achieve requirements without waste in the design. At Schaeffler, we use specialized tools for eMotor optimization –… Read more »
Optimizing electric motors for EV range, cost and sustainability (Webinar)
Sustainability is one of the fundamental features in electric motors. Whether it is a traditional PSM motor or advanced magnet-free motor with powered rotor coils, Schaeffler focuses on optimal use of both the space and materials to achieve requirements without waste in the design. The company uses specialized tools for eMotor optimization—looking at torque, power,… Read more »
ZF makes magnet-free electric motor
The permanent-magnet synchronous motor is the type of motor most frequently used in EVs, but it is based on magnets that require rare earth materials, which gives automakers an incentive to seek alternatives. As readers of Jeffrey Jenkins’s regular articles know, there are various other options, each with its own pros and cons regarding use… Read more »
ZF demonstrates new electric drivetrain and networked chassis technology
German automotive supplier ZF has developed a new thermal management system for EVs as part of its electromobility shift. Along with ZF’s optimized drivetrain, the new software “makes a significant contribution to higher efficiency,” according to the company. The new drive system is 30% lighter and can potentially boost winter vehicle range by up to… Read more »
Proterial prototypes 100 kW motor using ferrite magnets
Proterial (previously Hitachi Metals), a manufacturer of iron and metals, has found that optimizing the design of a motor using its patented high-performance ferrite magnet NMF-15 can achieve the same output as an EV drive motor that uses neodymium magnets. Proterial has validated maximum power of 102 kW and maximum rotation speed of 15,000 rpm,… Read more »
EU study examines shortage of critical metals for EVs
We’ve been reading a lot about looming shortages of battery raw materials such as lithium, nickel and graphite. But EV motors and electronics also use rare earths and other critical metals, which have their own set of supply constraints. A recent survey led by Sweden’s Chalmers University of Technology on behalf of the European Commission… Read more »
European HEFT project targets cheaper, more efficient, power-dense motor for EVs
In a €4-million HEFT research project directed by Mondragan University, eight EU partners including GKN Automotive will create a “lower-cost, more efficient and power-dense” permanent magnet motor for EVs. HEFT is an EU Horizon 2020 project focused on designing and manufacturing EV motors with reused and recycled permanent magnets. HEFT recommends energy-efficient rare earth synchronous… Read more »
