Generalized Dynamic Hysteresis Model for Improved Iron Loss Estimation of Complex Flux Waveforms
IEEE transactions on magnetics, 2019This paper presents a generalized dynamic hysteresis model for estimating the iron loss of complex flux waveforms. A versatile measurement system is developed to experimentally investigate the magnetic and iron loss properties of the studied soft ...

The determination of menstrual iron loss
Biochemical Medicine, 1970Abstract A procedure involving dry ashing and spectrophotometry with thioglycollic acid is described for the determination of iron loss during menstruation. In its development the nonvolatility of iron was checked and wet-oxidation and dry-ashing methods of destroying organic matter compared with special reference to citrated whole blood.

Armature Iron Losses in Series Motors
Transactions of the American Institute of Electrical Engineers, 1949IN 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.

2015 IEEE International Electric Machines & Drives Conference (IEMDC), 2015
This paper addresses the influence of the estimation of hysteresis, eddy current and excess loss coefficients on the prediction of the overall iron losses in traction motors. Two standard iron loss models (according to Bertotti and Jordan) are presented and it is examined how the determination of the corresponding loss coefficients is effecting the ...

Iron losses in processing tailings
Journal of Mining Science, 2005For ferruginous quartzite of the Mikhailovsk deposit, the features of mineral composition, iron occurrence, granulometric composition, and opening of phases of stage and total tailings of processing are considered. Extraction of hematite from tailings using combined concentration schemes is one of the variants of complex utilization of mineral source ...
