On the estimate of eddy current losses in current carrying conductors

Journal of Applied Physics, 2000
It is shown that ohmic losses in current carrying conductors at nonzero frequency can be decomposed into two parts. One part is due to a current distribution that would have existed within the conductor at zero frequency (dc current distribution).

Eddy current losses in round conductors

27th International Spring Seminar on Electronics Technology: Meeting the Challenges of Electronics Technology Progress, 2004., 2005
Eddy current losses in round conductors are discussed. An analytical approximation is presented. The proposed solution considers the wire diameter, the number of layers and wires in parallel, the distance from a possible air gap, the horizontal and vertical copper filling factors.

Eddy-current power loss in laminated iron cores

ISCAS 2001. The 2001 IEEE International Symposium on Circuits and Systems (Cat. No.01CH37196), 2002
This paper presents an analysis of power losses in gapless laminated iron cores at high frequencies. First, the magnetic field intensity is found. Next, the eddy current density is determined. Finally, expressions for the power loss density and the power loss per unit volume of an iron core are derived.

Eddy-Current Losses in Rectifier Transformers

IEEE Transactions on Power Apparatus and Systems, 1970
Two methods are developed for evaluating the eddy- current losses occurring in a rectifier transformer during operation, i.e., when carrying pulsating currents. The first is based on the analysis of the whole waveshape; the second starts from the harmonic composition of current curves.

Eddy current loss in grooved solid poles

IEEE Transactions on Magnetics, 1978
In this paper, the approximate equivalent circuit of the grooved solid pole synchronous motor is derived. In the approximate equivalent circuit, the upper part (grooved part) and the lower part (core part) of the grooved solid pole synchronous motor are separated.

Eddy current losses in PM canned motors

The XIX International Conference on Electrical Machines - ICEM 2010, 2010
Different 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 due to alternating current strips

IEEE Transactions on Power Apparatus and Systems, 1975
A two dimensional solution for the vector potential and eddy current loss in a plurality of conducting regions due to a plurality of current sources is presented. The solution is applicable to those problems with boundaries which may be aligned with the coordinate surfaces of an orthogonal system of separable coordinates.

Analytical solutions to eddy current and excess losses

COMPEL - The international journal for computation and mathematics in electrical and electronic engineering, 2005
Summary: 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.
