New Generation of Electrical Machines Enabled by Additive Manufacturing

我们项目的目标是建立一个由电机和添加剂制造(AM)领域的知名大学和行业合作伙伴组成的联盟，以全面研究和扎实开发用于关键应用的新一代电机。具体来说，我们将把实现我们目标的不同必要步骤整合到一个行业-博士网络中。这些包括多材料(软磁和非磁性材料)转子、3D结构AM导体、多材料(软磁和永磁体材料)以及对添加制造的EM的多物理研究。我们项目的目标是：a)构思受益于AM的3D几何自由度的电机的新概念，b)研究多材料添加剂制造的潜力并奠定基础，以提高电磁性能，具体增加功率密度，增加扭矩密度，降低铜耗，减少铁耗，减少谐波影响，c)建立网络，培养对添加剂制造工艺和电机都有深刻知识的合格工程师，以加速该技术的工业应用。D)建立一个由学术界和工业界组成的以知识为基础的专家小组，以代表欧洲坚实的创新，并保持欧盟在该领域的先锋作用；e)在电机领域取得必要的突破性技术，以加快相关应用的技术发展；f)鉴于原材料短缺，降低对材料的严格要求，特别是对稀土磁铁的要求。我们希望利用AM来解决目前在电机方面的技术障碍，以加快汽车和航空等领域对二氧化碳减排有直接影响的电气驱动的发展。

The goal of our project is to establish a consortium of renowned universities and industry partners in the field of electrical machines and additive manufacturing (AM) for a comprehensive study and solid development of new generation of electrical machines for key applications. In detail we will integrate different necessary steps for realizing our goal into an industry-doctoral network. These include multi-material (soft magnetic and non-magnetic materials) rotor, 3D-structured AM conductors, multi-material (soft magnetic and permanent magnet material) and multi-physical study of additive manufactured EMs. the objectives of our projects are: a) conceiving new concepts of electrical machines that benefit from the 3D geometrical freedom of AM, b) studying the potential and laying the foundations of multi-material additive manufacturing to enhance the EM performance, concretely increasing the power density, increasing the torque density, reducing the copper losses, reducing the iron losses, reducing the harmonic effects, c) establishing a network for educating qualified engineers with deep knowledge on both additive manufacturing processes and electrical machines to accelerate the industrial application of this technology, d) establishing a founded knowledge-based group of experts from academic and industry to represent a solid European innovation and to maintain the pioneering role of the EU in this field, e) reaching the necessary breaking-through technology in electrical machines to accelerate the technological development in related applications, f) reducing the stringent material requirements, particularly focusing on rare-earth magnets, in the light of raw materials shortages. We want to use AM to solve the current technological obstacles regarding electrical machines to accelerate the developing of electrical drives in areas such as automotive and aviation with direct impact on CO2 reduction.
