Sakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2017 Low voltage winding leads cause local eddy current losses in top-plate of the transformer tank. In this paper, this loss component which also causes local hot spots is investigated. Top-plate design is modified using stainless steel non-magnetic material,

A.C. loss contributions of the transport current and transverse field caused by combined action in a multifilamentary wire [PDF]
, 1985 A.c. losses caused by an a.c. transport current and a transverse a.c. magnetic field during simultaneous action were measured. The loss contributions have been obtained separately.

Classical eddy current losses in soft magnetic composites [PDF]
Journal of Applied Physics, 2013 This paper deals with the problem of loss evaluation in Soft Magnetic Composites (SMCs), focusing on the classical loss component. It is known that eddy currents can flow in these granular materials at two different scales, that of the single particle (microscopic eddy currents) and that of the specimen cross-section (macroscopic eddy currents), the ...

Rotor Eddy-Current Loss in Permanent Magnet Brushless Machines [PDF]
IEEE Transactions on Magnetics, 2004 This paper presents an analysis of the rotor eddy-current loss in modular and conventional topologies of permanent magnet brushless machine. The loss is evaluated both analytically and by time-stepped finite-element analysis, and it is shown that it can be significant in both machine topologies.
