Permanent Magnet Synchronous Motors and Rare-Earth Magnet Materials
This community focuses on the design, control, and material science of permanent magnet machines, primarily for electric drive applications in transportation and industrial systems.
The research centers on permanent magnet synchronous motors (PMSMs) and generators, with a heavy emphasis on control strategies such as model predictive control, sliding mode control, and sensorless operation. A significant portion of the work addresses the underlying magnet materials, specifically neodymium-iron-boron (NdFeB) alloys, including grain boundary diffusion techniques to enhance magnetic properties. Applications frequently cited include electric vehicles, wind power generation, and specialized linear machines. The literature also covers fault-tolerant designs, torque ripple minimization, and multi-phase machine configurations to improve reliability and performance in demanding environments.
The community represents a substantial share of research involving neodymium, accounting for 10.1% of all neodymium-related papers, and 8.5% of samarium research. It also constitutes 2.5% of iron research and 2.3% of boron research, reflecting the critical role of these elements in high-performance magnet production.
There are 10,961 papers in this community, published most frequently in IEEE Transactions on Magnetics, IEEE Transactions on Industrial Electronics, and the Journal of Magnetism and Magnetic Materials.
Recent work continues to focus on advanced control algorithms for PMSMs, including fault-tolerant control for multi-phase motors and digital twin-assisted fault diagnosis in wind power systems. Newer studies also explore high-temperature magnetic materials and the optimization of axial flux machines for emerging applications such as electric aircraft propulsion.
