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 (EV) 需求的增加导致电动机 (e-motor) 所需的稀土元素 (REE) 消耗量增加，因此这些材料的开采和提取也随之增加。 95% 的电动汽车 (EV) 使用基于稀土元素的牵引电机，例如钕铁硼 (NdFeB)。随着电动汽车需求的增加，对稀土元素的采购需求将不可避免地增加，预计到 2030 年全球消费量将达到 70kt/年。然而，电动汽车中使用基于稀土元素的电机存在两个主要问题：(i) 对环境的影响很大，因为它们是使用破坏环境的工艺进行提取和精炼的；(ii) 它们通常出现在地缘政治风险高的地区，例如中国（约占全球供应的 60%）， 该项目将使合作伙伴能够通过改变牵引电机的设计方式、不含稀土元素，加速开发真正对环境影响极低的电动汽车 (EV)。
