Bentley to study magnet recycling for electric motors

Bentley Motors will conduct a three-year research project to provide a sustainable source of rare-earth magnets for electric motor applications.

Building on work completed at the University of Birmingham, the study, titled Rare-earth Recycling for E-machines (RaRE) hopes to devise a method of extracting magnets from waste electronics.

The project will also scale up the new process and “repurpose the extracted magnetic material into new recyclable magnets for use within bespoke ancillary motors.”

The study supports Bentley’s commitment to offer only hybrid or electric vehicles by 2026, with the result showing the potential for recycled rare-earth magnets used in selected ancillary motors for the first time.

“As we accelerate our journey to electrification, offering only hybrid or electric vehicles by 2026, and full electric by 2030, it is important that we focus on every aspect of vehicle sustainability, including sustainable methods of sourcing materials and components,” said Bentley Motors engineering board member, Dr Matthias Rabe.

“RaRE promises a step-change in electrical recyclability, providing a source of truly bespoke, low voltage motors for a number of different applications and we are confident the results will provide a basis for fully sustainable electric drivers.”

Funded by Office for Zero-Emission Vehicles and delivered in partnership with Innovate UK, the project is aiming for its first application by 2026.
