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）的消耗增加，因此这些材料的开采和提取增加。95%的电动汽车（EV）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，不可避免地需要增加稀土资源，预计到2030年全球消耗量将达到70 kt/年。然而，在电动汽车中使用稀土电机存在两个主要问题：（一）由于采用对环境有害的工艺进行开采和提炼，对环境的影响很大;（二）通常在地缘政治风险很高的地点发现，例如中国（约占全球供应量的60%），这对供应和成本的安全性产生了影响。该项目将使合作伙伴能够通过改变牵引电机的设计方式，加快电动汽车（EV）的开发，真正降低对环境的影响，不含稀土元素。
