Magnetic Loss Analysis in Coaxial Magnetic Gears [PDF]

open access: yesElectronics (Switzerland), 2019
This paper proposes a procedure for computing magnetic losses in coaxial magnetic gears. These magnetic structures are made of permanent magnets and ferromagnetic poles in relative motion transferring torque between two shafts in a contactless way. The loss computation in magnetic materials is crucial to define the system performance.

Magnetization loss of nanocrystalline soft magnets [PDF]

open access: yesJournal of Physics: Conference Series, 2009
FeCuNbSiB-ribbons with optimized nanocrystalline microstructure possess a unique combination of near-zero magnetostriction, high saturation induction and low magnetization losses. Due to the absence of distinct intrinsic anisotropies, the magnetization curve can be adjusted by field-annealing to square or flat shape. It is well known that excess losses
