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 ...

Core Loss Analysis of Interior Permanent Magnet Synchronous Machines under SVPWM Excitation with Considering Saturation

Energies, 2017
Core loss is one of the significant factors affecting the high power density of permanent magnet machines; thus, it is necessary to consider core loss in machine design. This paper presents a novel method for calculating the core loss of permanent magnet

SYNCHRONIZATION AND ANTI-SYNCHRONIZATION OF CHAOS IN PERMANENT MAGNET RELUCTANCE MACHINE

Far East Journal of Dynamical Systems, 2007
In this paper, we investigate chaos synchronization and anti-synchronization between two coupled permanent magnet reluctance machines (PMSM) exhibiting chaotic behaviour. Nonlinear controllers derived from nonlinear control theory are designed for a drive-response PMSM system so that the response system synchronizes and anti-synchronizes with the drive

Single‐molecule DNA flow‐stretch assays for high‐throughput DNA–protein interaction studies

FEBS Open Bio, EarlyView.
We describe an optimised single‐molecule DNA flow‐stretch assay that visualises DNA–protein interactions in real time. Linear DNA fragments are tethered to a surface and stretched by buffer flow for fluorescence imaging. Using λ and φX174 DNA, this protocol enhances reproducibility and accessibility, providing a versatile approach for studying diverse ...

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

Advanced Engineering Materials, EarlyView.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

Materials‐Driven Additive Manufacturing for Electrical Machines: Qualification‐Oriented Design Beyond Geometric Freedom

Advanced Engineering Materials, EarlyView.
This perspective reframes additive manufacturing for electrical machines as a qualification‐limited materials and architecture design problem. It links process–structure–property–performance relationships to magnetic, conducting, dielectric, and thermal property windows, highlighting where AM can enable segmented magnetic circuits, permanent magnet ...
