Lightweight, Low Rare-earth, Permanent Magnet Motors for Electrified Future

Start year: 2025

Summary: This project seeks to push the envelope of the power to weight ratio of electric motors developed for transport electrification, aiming for over 5kW/kg using a novel Halbach magnet array with low rare-earth content and integrated stator cooling. This high-specific power breakthrough promises lighter, more efficient motors for electric vehicle, aircraft, and drones. The project will attempt to unlock the theoretical secrets of buried Halbach arrays, leading to a groundbreaking motor design and its drive system. The project will expand the knowledge base for future generations of high-specific-power electric machines and train the workforce for a sustainable, green future.
