Magnet Eddy Current Loss Reduction in Permanent Magnet Machines
IEEE transactions on industry applications, 2019 Magnet eddy current loss is very important for any types of permanent magnet (PM) machines, especially for high-speed PM machine since it increases significantly with rotating speed and has a great effect on the temperature of a magnet and, hence, the ...

Eddy-current loss prediction in the rotor magnets of a permanent magnet synchronous generator with modular winding feeding a rectifier load [PDF]
, 2011 In a permanent magnet synchronous generator (PMSG) with modular winding, significant eddy current may be induced in the rotor magnets due to asynchronous rotating stator magneto-motive forces (MMFs), and a rectifier load may signify the situation further.

Advanced Healthcare Materials, EarlyView.Osteoporosis from long‐term glucocorticoid (GIOP) use elevates susceptibility to fracture. This study shows GCs impair ascorbic acid (AA) metabolism in osteoblasts, collagen synthesis and extracellular matrix integrity. AA enhanced collagen biochemical and mechanical properties and restored osteoblast and endothelial function. These findings underscore
