EESM: Externally Excited Synchronous Motor

消费者对电动汽车（ev）需求的增加导致电动机（e-马达）所需稀土元素（REE）的消耗增加，因此这些材料的开采和提取也增加了。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，对稀土资源的需求将不可避免地增加，预计到2030年全球消费量将达到7万吨/年。然而，在电动汽车中使用基于稀土的电机存在两个主要问题：(i)环境影响很大，因为它们是通过破坏环境的过程提取和提炼的；（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，使合作伙伴能够加速真正低环境影响的电动汽车（ev）的开发，不含稀土元素。

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.
