High-Fidelity Voltage-Behind-Reactance Model of Electrically Excited Synchronous Machines Using Flux Maps

IEEE Open Journal of Industry Applications
Electrically excited synchronous machines (EESMs) have historically been used as efficient and reliable synchronous generators. However, the actual need for cost-effective, sustainable motors without rare-earth magnets has notably increased the interest ...

Influence of Temperature on Brushless Synchronous Machine Field Winding Interturn Fault Severity Estimation

Applied Sciences
There are numerous methods for detecting interturn faults (ITFs) in the field winding of synchronous machines (SMs). One effective approach is based on comparing theoretical and measured excitation currents. This method is unaffected by rotor temperature

Rare-Earth Reduction in Electric Traction Motors: A Design-Oriented Review Linking Topology, Magnetic Materials, Soft-Magnetic Cores and Windings Across Ground-Vehicle Segments

Energies
The electrification of ground transport is advancing under a constraint that is as much geopolitical as technical: the rare-earth elements used in high-energy permanent magnets, and especially the heavy-rare-earth additions required for high-coercivity ...
