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，以突破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) 虚拟传感功能，用于高保真地实时估计机器的运行状况； iii) 增强机器控制，减少 ii) 带来的设计和操作保守性； iv) 电动传动装置以提供增强的操作灵活性和能源效率； v) 基于数字孪生的优化，从早期设计阶段开始就嵌入生命周期分析和生命周期成本方面的系统考虑； vi) 采用回收永磁体和循环解决方案。拟议的创新将在新系列径向磁通直接驱动轮毂电机中实施，其特征是迄今为止尚未探索的扭矩密度水平（>150 Nm/升，>50 Nm/kg），以及车载单定子双转子型无铁芯轴向磁通电机，提供超过30 kW/升和10 kW/kg的功率密度和比功率水平。该解决方案将解决乘用车和货车应用（50 kW - 120 kW 的连续功率水平），提供具有竞争力的成本（25%），并减少 60% 以上的稀土含量，包括实施磁体回收解决方案。 EM-TECH获得了多家汽车制造商（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，进一步直接为相关欧洲目标和 KSO C 和 A 做出贡献。
