Electromagnetic buffering considering PM eddy current loss under intensive impact load [PDF]

, 2019
The intensive impact load will generate a huge acceleration in the primary part of the Electromagnetic buffers (EMBs), resulting in an instantaneous increase in the eddy current loss of the permanent magnet (PM).

Multi-field analysis of energy loss and temperature distribution in magnetic couplings

AIP Advances
The operation of magnetic couplings produces eddy current losses that lead to heat buildup. Excessive temperatures can demagnetize the couplings, ultimately causing transmission failure.

Value of MRI Outcomes for Preventive and Early‐Stage Trials in Spinocerebellar Ataxias 1 and 3

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To examine the value of MRI outcomes as endpoints for preventive and early‐stage trials of two polyglutamine spinocerebellar ataxias (SCAs). Methods A cohort of 100 participants (23 SCA1, 63 SCA3, median Scale for the Assessment and Rating of Ataxia (SARA) score = 5, 42% preataxic, and 14 gene‐negative controls) was scanned at 3T up ...

Classical eddy current losses in soft magnetic composites [PDF]

Journal of Applied Physics, 2013
This paper deals with the problem of loss evaluation in Soft Magnetic Composites (SMCs), focusing on the classical loss component. It is known that eddy currents can flow in these granular materials at two different scales, that of the single particle (microscopic eddy currents) and that of the specimen cross-section (macroscopic eddy currents), the ...

Estimation of Eddy-Current Loss for MnZn Ferrite Cores

, 2011
This paper proposes a new estimation for the eddy-current loss of MnZn ferrite cores. The eddy-current loss plays a critical role in the frequency range of 100-500 kHz, whereas the amount of the hysteresis loss dominates the core loss of magnetic devices

Normal‐Appearing White Matter Injury Mediates Chronic Deep Venous Hypoxia and Disease Progression in Multiple Sclerosis

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To explore how cerebral hypoxia and Normal‐Appearing White Matter (NAWM) integrity affect MS lesion burden and clinical course. Methods Seventy‐nine MS patients, including 13 clinically isolated syndrome (CIS) patients and 66 relapsing–remitting multiple sclerosis (RRMS) patients, and 44 healthy controls (HCs) were recruited from ...

Experimental and Theoretical Study of Interlaminar Eddy Current Loss in Laminated Cores

, 2017
Insulation failure between the electrical sheets of electrical machines or transformers might occur due to the burrs formed during the cutting process. Together with welding seams or screws used to hold the stack together, the burrs provide a conducting ...

Geometrical control of eddy currents in additively manufactured Fe-Si

Materials & Design, 2023
Additive manufacturing has enabled the processing of high silicon electrical steels which have excellent soft magnetic properties. In bulk form, core losses as a result of eddy currents would be too large to allow their use in high-frequency electrical ...
