Renault and Valeo have made headlines with the development of the E7A, a rare-earth free engine that could revolutionize the automotive industry. This innovative engine is designed to provide 200 kW of power while reducing CO2 emissions by almost double compared to traditional motors.
The decision to create a rare-earth free engine was driven by a variety of factors, including the environmental impact of rare earth mining and the instability of relying on limited and costly materials. China’s control over 90% of rare earth production also played a role, as it makes prices susceptible to geopolitical tensions.
The E7A operates without rare earth magnets, using a unique SR design that relies on electromagnetic induction between the rotor and stator. This design not only eliminates the need for expensive rare earth materials but also streamlines production with more abundant and accessible materials like steel and copper.
By developing this rare-earth free engine, Renault and Valeo are setting a new standard for environmentally friendly and sustainable automotive technology. With a 30% reduction in emissions and unprecedented power, this engine could pave the way for a more sustainable future in the automotive industry.
As the world continues to prioritize environmental sustainability and reducing reliance on limited resources, the E7A represents a significant step forward in creating a more eco-friendly transportation system. With the potential to reshape the automotive industry, the development of the rare-earth free engine is a milestone in the quest for a greener future.
