Innovative Collaboration for Sustainable E-Mobility
Valeo and MAHLE have partnered to develop a high-performance e-axle, achieving up to 350 kW using the iBEE system. This collaboration focuses on creating magnet-free electric motors that offer superior efficiency, performance, and environmental benefits.
Magnet-Free Motors: A Leap Forward
The partnership emphasizes electrically excited synchronous machines (EESM), which do not rely on rare earth materials. These motors are more resource-efficient, reduce CO₂ emissions, and improve the sustainability of electric vehicles. The goal is to create an e-axle for electric vehicles ranging from 220 to 350 kW.
Technological Milestones and Prototypes
Prototypes of the new e-axle are expected to be tested by the end of 2024. Valeo brings expertise in electric motor and power electronics, while MAHLE contributes advanced technologies for magnet-free rotors and a contactless transmitter (MCT). The collaboration also includes a new cooling system to optimize performance.
Sustainability and Cost Efficiency
Magnet-free motors reduce reliance on rare earth materials, cutting CO₂ emissions by over 40% compared to traditional motors. Additionally, by eliminating costly raw materials, the new design offers cost benefits and greater price stability, alongside reduced maintenance due to wear-free operation.
High Performance and Future Prospects
The iBEE system delivers up to 30% higher power density than current electric motors, making it ideal for larger, high-performance EVs. Valeo and MAHLE’s partnership is a major step toward efficient, sustainable solutions for the future of e-mobility.
Conclusion: A New Era of Sustainable Mobility
Through the development of magnet-free electric motors, Valeo and MAHLE are setting new standards for eco-friendly and high-performance drive technologies. Their innovative collaboration marks a significant step toward a sustainable future for electric vehicles.
