Revolutionising EV Propulsion: YASA’s Strategic Move Towards Rare-Earth Independence
In a significant stride towards sustainable and resilient electric vehicle (EV) manufacturing, YASA, a pioneer in electric motor technology, has embarked on a groundbreaking initiative to develop axial flux motor designs that either reduce or completely eliminate rare-earth magnet content. This critical project, dubbed ‘Project Resilience,’ has secured substantial funding through the UK government’s DRIVE35 Demonstrate competition, with all development work to be conducted at YASA’s advanced engineering and development facilities within the United Kingdom.
The imperative to move away from heavy rare earths in permanent magnet designs is increasingly vital for the high-performance battery-electric and hybrid vehicle sectors. YASA’s strategy aims to maintain exceptional power density without increasing the overall mass or package size of the motor, ensuring no compromise on vehicle performance. Concurrently, the company is dedicating efforts to developing fully rare-earth-free axial flux technology, specifically targeting vehicle applications that present varying performance, cost, and manufacturing requirements across the automotive spectrum.
Innovating Through Modular Axial Flux Motor Technology
At the heart of YASA’s innovative approach lies the development of two distinct yet complementary axial flux motor designs. This dual-pathway strategy is engineered around a common stator technology, fostering the potential for a highly flexible and modular motor architecture. This design philosophy is pivotal, enabling vehicle manufacturers to select different rotor technologies that precisely align with the specific demands of each vehicle program they undertake.
The adoption of a shared stator technology offers a multifaceted advantage. It not only streamlines engineering, design, and development processes but also facilitates the transfer of crucial manufacturing knowledge across both rare-earth reduction pathways. This strategic commonality significantly broadens the range of applications where YASA’s cutting-edge axial flux technology can be effectively deployed, spanning a wider array of electric vehicle segments and performance envelopes.
Addressing Critical Supply Chain Vulnerabilities
The global automotive industry has long grappled with the inherent risks associated with the supply chains for rare-earth permanent magnets. These supply chains are characterized by their highly concentrated geographical nature, a factor that exposes automotive manufacturers and their suppliers to a spectrum of challenges. These include potential export restrictions imposed by producing nations, significant price volatility influenced by market dynamics and geopolitical events, and the pervasive threat of supply disruption.
Heavy rare earths, in particular, are commonly employed to enhance the resilience of permanent magnets, enabling them to endure the extreme temperatures and demanding operational conditions characteristic of electric motors. However, their extraction and processing are often complicated and recognized for their carbon-intensive nature. Project Resilience directly confronts these vulnerabilities, seeking to fortify the supply chain by developing alternatives that mitigate dependence on these critical, yet problematic, materials.
The UK Government’s Strategic Investment: DRIVE35 and Project Resilience
Project Resilience is an integral component of the broader DRIVE35 program, an initiative spearheaded by the Department for Business, Innovation, Science and Trade. This program operates in close partnership with the Advanced Propulsion Centre UK (APC) and Innovate UK, aligning with the national agenda to advance key industrial sectors.
DRIVE35 forms a crucial part of the UK government’s ambitious Advanced Manufacturing Sector Plan, a comprehensive strategy that earmarks a substantial £4 billion in grant funding. This funding, available up to 2035, is specifically dedicated to supporting automotive Research and Development (R&D), facilitating scale-up operations, and driving transformative changes within the industry. Project Resilience, as one of ten Demonstrate projects collectively announced, shares a significant portion of £9 million in government funding. The APC has further indicated that the combined government and industry investment across these ten projects surpasses £18 million, underscoring a robust commitment to innovation.
A key mandate for projects funded through the Demonstrate competition, as outlined by the APC, is the requirement to build a product or process demonstrator within a stringent 12-month timeframe. While the precise size of YASA’s individual award under Project Resilience was not publicly disclosed, its inclusion highlights the strategic importance placed on its developments for the future of the UK’s automotive sector.
Tailoring Solutions for Diverse EV Applications
Tom Hillman, YASA’s Head of Motor Simulation, articulated the core philosophy guiding Project Resilience. “Project Resilience is about creating credible alternatives without losing sight of what vehicle manufacturers need from an electric motor,” Hillman stated. This perspective emphasizes a pragmatic approach, recognizing the varied and often unique demands of different EV applications.
Hillman further elaborated on this point, explaining that “Different applications require different balances of performance, efficiency, packaging, cost and production volume, which is why we are developing two complementary technology routes rather than pursuing a single universal solution.” This highlights YASA’s commitment to providing flexible, tailored solutions that cater to the diverse needs of the evolving electric vehicle market, from high-performance sports cars to more cost-sensitive mass-market vehicles, ensuring optimal integration and efficacy.
The Future of Sustainable EV Drivetrains
YASA’s endeavors under Project Resilience are more than just technical advancements; they represent a strategic imperative for the future of sustainable mobility. By tackling the reliance on rare-earth elements, the project aims to foster greater supply chain security, reduce environmental impact, and pave the way for a new generation of high-performance, cost-effective, and environmentally responsible electric motors. This initiative firmly positions the UK at the forefront of electric vehicle innovation, driving forward a greener, more resilient automotive future.
