| Abstract Scope |
Ever-evolving geopolitical tensions have brought heavy rare earth (HRE) criticality back into focus. The usage of HREs in permanent magnets is key to achieving both high energy density and temperature stability in NdFeB-based magnets, particularly for traction motor applications. Optimizing the usage of HREs in traction motors has been limited by the ability of finite element analysis (FEA) methods to accurately predict demagnetization. In this talk, we discuss how multi-scale modeling is used to guide permanent magnet fabrication and to improve the ability to predict demagnetization during a drive cycle using FEA. This work discusses how we are leveraging advances in powder metallurgy, combined with microstructural and motor-level multi-physics modeling, to design permanent magnets architectures with optimized efficiency of HRE usage. Our approach enables a path to design permanent magnet architectures for specific motor designs, enabling rapid design iteration to minimize demagnetization and HRE usage while improving overall motor performance. |
