Design Consideration of Eddy-Current Loss for Rotor of HIA With Rectifier and Capacitive Loads
IEEE Transactions on Plasma Science, 2018Homopolar inductor alternator (HIA) with rectifier and capacitive loads is a promising choice for pulsed power supply. The solid-iron rotor of HIA can rotate at a very high speed, but this causes serious eddy-current loss in the rotor and results in ...

Eddy current loss calculation in multiconductor systems
IEEE Transactions on Magnetics, 1983This paper presents the application of the finite element technique for calculating eddy current losses in multiconductor systems used in power transmission. This paper is a contribution to skin effect analysis in conductors and enclosures of arbitrary shapes.

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 losses in PM canned motors
The XIX International Conference on Electrical Machines - ICEM 2010, 2010Different approaches for the determination of eddy current losses in PM canned motors are presented. After a general description of the problem, an analytical model will be derived, which will be compared to numerical FEM calculations. In addition, the influence of the most important design parameters of the can will be discussed.

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 saturable magnetic materials
IEEE Transactions on Magnetics, 1994In this paper, a finite element method, based on a variational formulation, is used to evaluate eddy current losses inside a nonlinear, saturable ferromagnetic material, for a two dimensional field problem. Boundary conditions are imposed in an integral form combined with Neumann conditions.

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.
