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.

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，以推动汽车牵引电机技术的界限：i）创新的直接和主动冷却设计; ii）用于高保真实时估计机器运行状况的虚拟传感功能; iii）增强机器控制，减少设计和操作保守性ii）; iv）电动传动装置，以提供更高的运营灵活性和能源效率; v）基于数字孪生的优化，从早期设计阶段就系统地考虑生命周期分析和生命周期成本方面;以及vi）采用回收永磁体和圆形解决方案。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，其特点是迄今为止未开发的扭矩密度水平（>150 Nm/L，>50 Nm/kg），以及车载单定子双转子型无铁芯轴向磁通电机，其功率密度和比功率水平超过30 kW/L和10 kW/kg。这些解决方案将同时适用于乘用车和货车应用（50 kW - 120 kW的连续功率水平），提供具有竞争力的成本（25%），并将稀土含量降低60%以上，包括实施磁铁回收解决方案。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将进一步直接为相关的欧洲目的地和KSO C和A做出贡献，支持在关键数字，使能和新兴技术领域建立欧洲领导地位，并发展各自的价值链。
