Content
The automotive industry is amidst an unprecedented multi-faceted transition striving for more sustainable passenger mobility and freight transportation. The rise of e-mobility is coming along with energy efficiency improvements, CO2 and non-exhaust emission reductions, driving/propulsion technology innovations, and a hardware-software-ratio shift in vehicle development for road-based electric vehicles. Current R&D activities are focusing on electric motor topologies and designs, sustainability, manufacturing, prototyping, and testing. This is leading to a new generation of electric motors, which is considering recyclability, reduction of (rare earth) resource usage, cost criticality, and a full product life-cycle assessment, to gain broader market penetration. This paper outlines the latest advances of multiple EU-funded research projects under the Horizon Europe framework and showcases their complementarities to address the European priorities as identified in the 2ZERO SRIA . The E-VOLVE cluster is mutually promoting many R&D projects, such as EM-TECH, HEFT, MAXIMA, VOLTCAR and CliMAFlux. EM-TECH develops novel electric motor technologies in combination with innovative e-axle and e-corner architectures for high-efficient and sustainable e-mobility. HEFT deals with the designing and manufacturing of electric motors equipped with re-used/recycled permanent magnets. MAXIMA creates an affordable and adaptable axial flux motor that offers improved performance, incorporates strategies for rare earth elements reduction, and has a minimal environmental impact. VOLTCAR investigates radial flux permanent magnet motors with the aim to ensure required performance, various sustainability criteria, as well as cost, reliability, and integrability issues. Finally, CliMAFlux, innovates the design and manufacturing processes of axial flux motors towards improved range, performance, circularity, and reduced costs.
