HEFT considers that an energy efficient rare-earth synchronous motor is the best option for next generation high-power primary axle traction EVs and proposes a set of innovation challenges on electric synchronous motor configuration based on SiC inverters (direct cooling of rotor and stator, advance insulation for high voltage, multibarrier rotor topology, wave windings) and advanced materials (advanced GBD magnets, epoxy for magnet fixation, composite for motor housing, insulation resin). These innovations will result in a high-efficient and low-cost solution that will be validated on 2 motor topologies, which compared to two main reference automotive IPM commercial motors in Europe (VW ID.3 and FIAT500) will lead to next impacts: >800V, 20% reduction losses, >7 KW/kg and 42kW/ l power density, 28% cheaper, 50-66% material savings, including 60% reduction of REE content and >80% REE recyclability rate. As this solution is still dependent on REE from China, HEFT will be aligned with the ERMA action plan towards a circular economy market of rare earth permanent magnets and suggests: one alternative magnet route (Ce based) and two REE recycled routes together with policies promotion towards the foundation of a European rare earths industry, capable of delivering 20% of EU demand by 2030. HEFT plans 8 WPs to implement these concepts, where 5 research partners will be essential for developing innovative ideas around the design-to-x approach, while strong companies (GKN Automotive, MAGNETI, VYNCOLIT) will ensure that HEFT results have a clear market orientation and fulfil the industry needs. HEFT plans to organise OEM workshops to ensure wide adoption of HEFT solutions, but also with policymakers to promote regulations towards the EU circular market that would help maintaining the leadership of EU companies, while increasing their competitiveness and job opportunities linked to the new circular business models.

HEFT认为高效节能的稀土同步电机是下一代大功率主轴牵引电动汽车的最佳选择，并提出了一系列基于SiC逆变器（转子和定子直接冷却、高压高级绝缘、多层转子拓扑、波形绕组）和先进材料（先进GBD磁体、磁体固定环氧树脂、 电机外壳复合材料、绝缘树脂）。这些创新将产生高效、低成本的解决方案，该解决方案将在 2 种电机拓扑上进行验证，与欧洲的两种主要参考汽车 IPM 商用电机（VW ID.3 和 FIAT500）相比，将带来以下影响：>800V，损耗减少 20%，功率密度 >7 KW/kg 和 42kW/l，便宜 28%，节省 50-66% 材料，包括 REE 减少 60% 含量和 >80% 的 REE 可回收率。由于该解决方案仍然依赖于中国的稀土元素，HEFT 将与 ERMA 稀土永磁体循环经济市场行动计划保持一致，并建议：一条替代磁体路线（基于 Ce）和两条 REE 回收路线以及欧洲稀土行业基础的政策促进，到 2030 年能够满足欧盟需求的 20%。HEFT 计划建立 8 个工作区来实施这些概念，其中 5 个研究合作伙伴对于开发 围绕设计到 X 方法的创新理念，而实力雄厚的公司（GKN Automotive、MAGNETI、VYNCOLIT）将确保 HEFT 结果具有明确的市场导向并满足行业需求。 HEFT 计划组织 OEM 研讨会，以确保广泛采用 HEFT 解决方案，同时与政策制定者一起推动欧盟循环市场的监管，这将有助于保持欧盟公司的领导地位，同时提高其竞争力和与新循环商业模式相关的就业机会。
