The increase in consumer demand for electric vehicles (EVs) has led to increased consumption of rare earth elements (REE) being required for electric motors (e-motors) and hence mining and extraction of these materials have increased. 95% of electric vehicles (EVs) use traction motors based on REE, such as Neodymium iron boron (NdFeB). Inevitably as the demand for EVs increases, the need to source REE's will increase with global consumption projected to reach 70kt/year by 2030\.However, the use of REE-based motors within EVs presents two main issues: (i) Environmental impact is high as they are extracted and refined using environmentally damaging processes and (ii) they are usually found in locations with high geopolitical risks, such as China (~60% of global supply), which impacts security of supply and cost.This project will enable the partners to accelerate the development of electric vehicles (EVs) with a truly low environmental impact, by transforming the way traction motors are designed, free from REEs.

消费者对电动汽车(EVS)的需求增加，导致电动马达(E-Motors)所需的稀土元素(REE)消费量增加，因此这些材料的开采和开采增加。95%的电动汽车(EVS)使用基于稀土元素的牵引电机，如钕铁硼(NdFeB)。随着电动汽车需求的增加，对稀土的需求将不可避免地增加，预计到2030年，全球消费将达到70kt/年。但基于稀土的电机在电动汽车中的使用存在两个主要问题：(I)环境影响很大，因为它们是使用破坏环境的工艺提取和提炼的；(Ii)它们通常位于地缘政治风险较高的地区，如中国(约占全球供应量的60%)，这影响了供应安全和成本。该项目将通过改变牵引电机的设计方式，使合作伙伴能够加快开发对环境影响真正低的电动汽车(EVS)。摆脱里斯的束缚。
