The project aims to develop novel electric motor topologies by using advanced magnetic materials and manufacturing techniques. The project main tasks will be to identify, design, simulate, build and optimize innovative motor topologies using 3D magnetic flux path designs. These topologies will be enabled by developing simultaneously soft and hard magnetic materials and manufacturing processes. Soft magnetic composites (SMC) offers unique isotropic magnetic properties compared to laminations that can enable several advantages for the fabrication of machines and stators in particular. Using the cold spray process for the fabrication of a M-NdFeB composite, the National Research Council of Canada (NRC) have shown that it is possible to build complex shaped permanent magnets that cannot be realized on rotors using traditional fabrication methods. These two materials also offers manufacturing advantages such as reduced part counts and assembly steps that can significantly reduce the cost of the electric motor. Both the advantages of the 3D magnetic flux and the manufacturability will be clearly established in this project by building and testing various prototypes. Rio Tinto Metal Powders (RTMP) of Quebec, Canada, in collaboration with the NRC in Boucherville, QC, will improve the performance and the fabrication process of SMC powder grades while NRC will continue the development of the cold spray permanent magnet technology. The expertise of Concordia University on electric motor design and on finite element analysis will be required to develop permanent magnet motor topologies that would benefit from 3D magnetic flux. The support of Stackpole, a producer of powder metallurgy components, for the fabrication of the prototypes will ensure the achievement of this project objective.

该项目旨在通过使用先进的磁性材料和制造技术来开发新型的电动机拓扑。项目主要任务将使用3D磁通路径设计识别，设计，模拟，构建和优化创新的电机拓扑。这些拓扑将通过同时开发柔软和硬磁性材料和制造工艺来启用。与层压板相比，软磁复合材料（SMC）提供了独特的各向同性磁性特性，这些层压层可以使计算机和法规的制造能够获得多种优势。加拿大国家研究委员会（NRC）使用冷喷雾过程来制造M-NDFEB复合材料，表明可以使用传统的制造方法建造无法在转子上实现的复杂形状的永久磁铁。这两种材料还提供了制造优势，例如减少的零件计数和装配步骤，可以显着降低电动机的成本。 3D磁通量的优势和制造性都可以通过构建和测试各种原型来确定。 加拿大魁北克的Rio Tinto Metal Powders（RTMP）与NRC在质量控制的NRC合作，将改善SMC粉末等级的性能和制造过程，而NRC将继续开发冷喷雾剂永久磁铁技术。 Concordia大学电动机设计和有限元分析的专业知识将需要从3D磁通量中受益的永久磁铁拓扑。粉末冶金成分生产商Stackpole的支持，用于制造原型，将确保实现该项目目标。
