Renault promises to transform the automotive sector with its innovative electric engine, which eliminates the need for rare materials exclusive to China.
With an impressive advancement in the field of automotive engineering, Renault is ready to redefine industry standards with its new electric motor, promising not only superior performance and weight reduction, but also eco-conscious innovation. Completely eliminating the need for rare earths, materials whose extraction has been associated with questionable environmental and social practices, this electric motor positions itself not only as a more powerful option, but also as a sustainable and ethical alternative.
By breaking dependence on exclusive materials from China, Renault stands out in the race for innovation, showing that it is possible to reach new levels of efficiency and performance without compromising environmental and social principles.
This is a giant step forward for the automotive industry and a clear sign that the future of electric vehicles is bright, powerful and responsible. Prepare to be surprised by an engine that promises to take the driving experience to a whole new level.

Renault develops new electric motor that does not require rare metals
Therefore, although everything indicates that we will have to rely on the Asian giant for this, there are many companies focused on developing a new Rare earth-free electric motor to reduce costs and overall CO2 emissions.
Among the carmakers leading the revolution is Renault, which 18 months after announcing its collaboration with Valeo, presented the first details of its E7A electrically excited synchronous motor, free of rare earths.
Renault is a specialist in electrically excited synchronous motors, having made its debut at ZOE in 2012. More than 10 years of experience was used to develop the new unit, an all-in-one type, as mentioned, free of rare earths.
According to data released by the company, the new Renault and Valeo engine is 30% smaller, with the same power, than the current electric motors that power models such as the Megane E Tech electric and the electric Scenic E-Tech.
The carbon footprint is 30% smaller. By using a wound rotor instead of permanent magnets, the automaker improves the efficiency of the new electric motor, protects your supply chain and avoids dependence on rare earth and magnet producing countries.
New Renault engine delivers 272 horsepower
According to official figures, the new rare earth-free E7A electric motor will also help reduce battery charging time. battery, as the system will be 800 volts, and the Valeo stator will increase power and efficiency. In fact, in its superior version, it will reach 200 kW, the equivalent of 272 horsepower, without weighing too much on autonomy. The new E7A electric motor unit is currently being tested, however, Renault plans to start series production at the Cléon plant (France) in 2027.
In addition to Renault, with its new rare earth-free electric motor, ZF is developing a series production-ready electric motor that does not require magnets.
In contrast to the magnet-free concepts of so-called externally excited electric motors already available today, ZF's I2SM transmits the energy to the magnetic field via an inductive exciter inside the rotor shaft. According to the company, this makes the engine uniquely compact with the highest power.
The new electric motor without magnets
According to the manufacturer, this more developed variant of an externally excited synchronous motor is an alternative to so-called permanent magnet synchronous machines (PSM).
The latter are currently the most used motors in electric vehicles, however, they are based on magnets that require rare earths to produce. With I2SM, ZF wants to make electric motors extremely sustainable in production and highly powerful in operation.
According to Dr. Holger Klein, CEO of ZF, with this electric motor without magnets and without rare earths, there is a major innovation with which it is consistently reducing its electric drive portfolio for sustainable, efficient and resource-saving mobility.
