If you are a car manufacturer dealing with high production costs for mass-market EVs — this project developed a motor that is 28% cheaper and reduces rare earth element content by 60%. This allows for more competitive pricing in the A and B vehicle segments.
Low-Cost High-Efficiency Recyclable Electric Motors for Mass Market EVs
Imagine an electric car motor that is cheaper to build and easier to recycle. Instead of relying on expensive and hard-to-get rare minerals from a single global source, this design uses recycled materials and alternative magnets. It's like upgrading a car's heart to be more powerful while using fewer precious resources.
What needed solving
EV manufacturers are struggling with high costs and supply chain vulnerabilities due to the reliance on rare earth elements (REE) primarily sourced from China.
What was built
A high-power density motor design using SiC inverters and a circular recovery process for magnets from end-of-life rotors.
Who needs this
Who can put this to work
If you are a supplier dealing with strict power density requirements — this project developed a motor achieving >7 KW/kg and 42kW/l power density. It integrates SiC inverters to reduce energy losses by 20%.
If you are a recycling firm dealing with the difficulty of extracting magnets from old rotors — this project developed a cost-effective recovery process with an >80% REE recyclability rate. This enables a closed-loop supply of magnets for second-generation motors.
Quick answers
How much does this solution reduce the cost of the motor?
The project aims for a solution that is 28% cheaper than current reference automotive motors.
Can this be produced at an industrial scale for mass market cars?
Yes, the project specifically targets mass-produced cars and vans, focusing on A+B and C+D vehicle segments.
What is the IP or licensing status of the technology?
Based on available project data, specific licensing terms are not mentioned, but the project involves 4 industrial partners including GKN and Magneti Marelli to ensure market orientation.
How does this affect the supply chain risk for rare earth materials?
It reduces primary rare earth CRM usage by over 60% and introduces a Ce-based magnet alternative to reduce dependency on Chinese imports.
What is the timeline for the development and validation?
The project period runs from December 1, 2022, to November 30, 2026.
Who built it
The consortium is well-balanced for commercialization, featuring a 44% industry ratio with 4 industrial partners (including GKN and MagnetI) and 4 universities. This mix ensures that the high-level research on magnet topology is immediately vetted against the practical needs of mass-market automotive production.
