Thermal performance analysis and optimization of a stator core water-cooling system for high-power-density permanent magnet synchronous motors

Case Studies in Thermal Engineering
The stator core water-cooling structure is an effective thermal solution for high-power-density permanent magnet synchronous motors (PMSMs). However, the additional thermal outlets of circulation loss and eddy loss introduced by the cooling pipes often ...

A Unifying Thermodynamic Model for Phase Separation and Aging of Biopolymers

Advanced Science, EarlyView.
Phase separation and aging of intrinsically disordered proteins are placed in a unifying framework. A thermodynamically consistent time‐dependent version of associating‐polymer theory shows how the processes are intricately coupled. Assuming aging to occur through interacting sites resulting from reversible conformational transitions, the model ...

Simulation of Eddy Current Losses in Twisted Wires

Periodica Polytechnica Electrical Engineering and Computer Science
Twisted wires made of insulated strands, known as stranded conductors or litz wires, are used in various areas where the eddy current loss within the wire needs to be reduced. These areas include induction heating, resonance-based wireless energy transfer, and certain radio frequency devices. Some litz wires consist of thousands of individual conductor

Curvature-related eddy-current losses in laminated axial flux machine cores [PDF]

, 2005
In this paper we present an axiperiodic quasi-static model to evaluate the magnetic flux density distribution and power loss due to curvature related radial flux in the laminated core of axial flux machines.

From Magnetic Fibers to Paper Architectures: A Lightweight Strategy for Robust Low‐Frequency Microwave Absorption

Advanced Science, EarlyView.
A scalable process converts para‐aramid fibers into soft‐magnetic building blocks via micrometer‐thick Fe0.64Ni0.36 (Invar‐type) coatings. Assembled into paper, they form a hierarchical conductive network whose tunable permeability enables thin, lightweight microwave absorption in the low‐frequency (S‐band) regime.
