Analytical solutions to eddy current and excess losses
COMPEL - The international journal for computation and mathematics in electrical and electronic engineering, 2005Summary: This paper sets out to develop analytical solution to the hysteresis, eddy current and excess losses using the \(T(x)\) model. Based on Steinmetz' postulation, the losses, represented by the area enclosed by the hysteresis loop, are individually formulated in analytical form.

Eddy current losses in laminated transformer cores
3D Africon Conference. Africon '92 Proceedings (Cat. No.92CH3215), 2003A finite element method, based on the variational principle, for two-dimensional field configurations is used to evaluate eddy current losses in a sheet of a laminated transformer core assumed to be a linear homogeneous conducting medium. Boundary conditions are imposed in an integral form combined with Neumann conditions.

Eddy-current losses in reactor flux shields
Proceedings of the Institution of Electrical Engineers, 1970The magnetic-field distribution is analysed for the case of an aluminium plate excited by a circular current loop, and an expression for the eddy-current loss in the plate is deduced. This analysis is tested by comparison with measurements on a model which closely resembles the theoretical geometry, and the results are shown to be in close agreement. A

Eddy-current losses in solid and laminated iron
Transactions of the American Institute of Electrical Engineers, Part I: Communication and Electronics, 1959In this paper formulas are developed, on the basis of simple physical conceptions, for the calculation of eddy currents in solid and laminated iron, which, as the experiments presented show, enable the losses caused by eddy currents to be predicted with surprising accuracy. A simple formula for the calculation of the power factor (pf) that the magnetic

Computing Eddy Current Losses in Reactor Coils
1988Reactor coils are electrical components which serve (among others) the following purposes: to limit the current under system fault conditions, to distribute the load to parallel circuits, to reduce the starting current that occurs when elec- trical machines are switched on, to limit short-circuit currents in rectifier equipments.

Eddy-current loss in a rotating magnetic field
Soviet Physics Journal, 1973The eddy-current loss is calculated for nonferromagnetic disks in a rotating magnetic field. The power loss is found as a function of the magnetic field intensity, the field rotation velocity, and the disk dimensions. The eddy-current loss was measured experimentally in rotating fields in copper, aluminum, and zinc disks; a good agreement was found ...
