Iron losses in sweat

The American Journal of Clinical Nutrition, 1986
The losses of iron in whole body cell-free sweat were determined in eleven healthy men. A new experimental design was used with a very careful cleaning procedure of the skin and repeated consecutive sampling periods of sweat in a sauna. The purpose was to achieve a steady state of sweat iron losses with minimal influence from iron originating from ...

Verification of Iron Loss Calculation Method using a High-Precision Iron Loss Analyzer

IEEJ Transactions on Industry Applications, 2013
SUMMARYBecause of the improved performance of power devices, the volume of the ac filter inductors used in high‐frequency PWM inverters has been reduced. However, the temperature rise in the filter inductor due to this miniaturization has become more pronounced.

Losses in silicon-iron

IEEE Transactions on Magnetics, 1974
Measurements of total power loss and domain-wall spacing have been made on individual grains in polycrystalline specimens of commercial grain-oriented 3% silicon-iron material. The loss-per-cycle against frequency characteristic of a grain is found to consist of discrete linear portions, which correspond to different domain-wall spacings. These changes

Annual Iron Loss Associated with Hemodialysis

American Journal of Nephrology, 2016
<b><i>Background:</i></b> In order to keep up the optimal iron status in chronic hemodialysis patients, it is important to know how much iron is lost due to hemodialysis. Residual blood associated with the hemodialysis procedure together with blood sampling inevitably causes the loss of iron in chronic hemodialysis patients ...

Armature Iron Losses in Series Motors

Transactions of the American Institute of Electrical Engineers, 1949
IN AN A-C series motor, the flux pulsation in the field is predominantly at line frequency. The field iron loss can be computed easily and represented by a loss component in the magnetizing current. However, due to the rotation of the armature, the gap flux is rotating relative to the armature, as well as pulsating.

Analysis of iron losses in induction motor with an improved iron-loss model

2014 IEEE Conference and Expo Transportation Electrification Asia-Pacific (ITEC Asia-Pacific), 2014
In order to study iron loss distribution characteristics in stator and motor of induction motor, an improved iron-loss model with higher accuracy is proposed based on time-stepping finite elements. In Section Two,various iron loss formulaes are compared. followed by an miproved iron-loss model.

Iron loss in machines with powdered iron stators

IEEE International Electric Machines and Drives Conference. IEMDC'99. Proceedings (Cat. No.99EX272), 2003
This paper describes iron loss measurements in a permanent magnet servomotor, which has a stator constructed with soft magnetic composites (SMCs). It is shown that whilst the SMC has significantly greater iron loss density than silicon iron steel, it has many other advantages. The SMC machine is shown to outperform its conventional laminated equivalent.
