Innovative e-motor technologies covering e-axles and e-corners vehicle architectures for high-efficient and sustainable e-mobility

EM-TECH汇集了来自工业界和学术界的10名参与者，通过以下方式开发新颖的解决方案，推动汽车牵引电机技术的发展：1)创新的直接和主动冷却设计；Ii)虚拟感知功能，用于高保真实时估计机器的运行状态；Iii)增强了机器控制，降低了设计和操作的保守性；Iv)电动传动装置，以提高操作的灵活性和能源效益；v)基于数字孪生的优化，从早期设计阶段就嵌入了生命周期分析和生命周期成本方面的系统考虑；六、采用回收永磁体和循环解决方案。提出的创新将在新系列的径向磁通直接驱动轮内电机中实施，其特点是迄今为止尚未开发的扭矩密度水平（>150纳米/升，>50纳米/公斤），以及车载单定子双转子型无铁轴向磁通电机，其功率密度和特定功率水平超过30千瓦/升和10千瓦/公斤。这些解决方案将适用于乘用车和厢式货车的应用（持续功率水平为50 kW - 120 kW），提供具有竞争力的成本（25%），并将稀土含量降低60%，包括磁铁回收解决方案的实施。EM-TECH获得了几家汽车制造商（奥迪和长安英国）的支持，这将加强开发战略。EM-TECH将通过支持在关键数字、赋能和新兴技术领域建立欧洲领导地位，以及各自价值链的发展，进一步直接为相关的欧洲目的地和KSO C和A做出贡献

EM-TECH brings together 10 participants from industry and academia to develop novel solutions to push the boundaries of electric machine technology for automotive traction, through: i) innovative direct and active cooling designs; ii) virtual sensing functionalities for the high-fidelity real-time estimation of the operating condition of the machine; iii) enhanced machine control, bringing reduced design and operating conservativeness enabled by ii); iv) electric gearing to provide enhanced operational flexibility and energy efficiency; v) digital twin based optimisation, embedding systematic consideration of Life Cycle Analysis and Life Cycle Costing aspects since the early design stages; and vi) adoption of recycled permanent magnets and circularity solutions. The proposed innovations will be implemented in new series of radial flux direct drive in-wheel motors characterised by so far unexplored levels of torque density (>150 Nm/litre, >50 Nm/kg), and on-board single stator double rotor type ironless axial flux machines providing power density and specific power levels in excess of 30 kW/litre and 10 kW/kg. The solutions will address both passenger car and van applications (continuous power levels of 50 kW - 120 kW), providing competitive costs (25%), and to >60% decrease of the rare earth content, including implementation of magnet recycling solutions. EM-TECH obtained the support of several car makers (AUDI and Changan UK), which will strengthen the exploitation strategy. EM-TECH will further directly contribute to the relevant European Destination and KSO C and A, by supporting the establishment of a European leadership in the sector of key digital, enabling and emerging technologies, and the development of the respective value chains
