Novel permanent magnet motor topologies using advanced magnetic materials

该项目旨在通过使用先进的磁性材料和制造技术开发新型电动机拓扑结构。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、构建和优化创新的电机拓扑结构。这些拓扑结构将通过同时开发软、硬磁性材料和制造工艺来实现。与叠片相比，软磁复合材料（SMC）具有独特的各向同性磁性能，特别是在制造电机和定子方面具有多项优势。使用冷喷涂工艺制造M-NdFeB复合材料，加拿大国家研究理事会（NRC）已经表明，可以构建使用传统制造方法不能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，例如减少部件数量和组装步骤，可以显着降低电动机的成本。3D磁通量和可制造性的优势将在该项目中通过构建和测试各种原型来明确建立。 加拿大魁北克的Rio Tinto Metal Powders（RTMP）与位于魁北克布切尔维尔的NRC合作，将改进SMC粉末等级的性能和制造工艺，而NRC将继续开发冷喷涂永磁技术。Concordia大学在电机设计和有限元分析方面的专业知识将被要求开发受益于3D磁通的永磁电机拓扑结构。粉末冶金部件生产商斯塔克波尔对原型制造的支持将确保该项目目标的实现。

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.
