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.

该项目旨在利用先进的磁性材料和制造技术开发新型电动机拓扑。该项目的主要任务是使用 3D 磁通路径设计来识别、设计、模拟、构建和优化创新电机拓扑。这些拓扑将通过同时开发软磁和硬磁材料以及制造工艺来实现。与叠片相比，软磁复合材料 (SMC) 具有独特的各向同性磁特性，可为机器和定子的制造带来多种优势。加拿大国家研究委员会 (NRC) 表明，使用冷喷涂工艺制造 M-NdFeB 复合材料，可以制造出使用传统制造方法无法在转子上实现的复杂形状的永磁体。这两种材料还具有制造优势，例如减少零件数量和组装步骤，从而可以显着降低电动机的成本。通过构建和测试各种原型，该项目将清楚地体现 3D 磁通量和可制造性的优点。 加拿大魁北克力拓金属粉末公司 (RTMP) 与位于魁北克省 Boucherville 的 NRC 合作，将改进 SMC 粉末等级的性能和制造工艺，同时 NRC 将继续开发冷喷涂永磁体技术。开发受益于 3D 磁通量的永磁电机拓扑需要康考迪亚大学在电机设计和有限元分析方面的专业知识。粉末冶金部件生产商 Stackpole 对原型制造的支持将确保该项目目标的实现。
