Eddy Current Phenomena in Laminated Structures Due to Travelling Electromagnetic Fields
By
Progress In Electromagnetics Research M, Vol. 18, 159-169, 2011
Abstract
The distribution of fields travelling in the laminated structure with assumed values for the tangential components of the magnetic field intensities on the top and bottom surfaces of the structure, has been obtained using linear electromagnetic field theory. The treatment takes cognizance of interlaminar capacitance inherently present in a laminated structure. Analysis presented in this paper assumes identical field distribution in each lamination and a given current sheet as the source for the travelling electromagnetic fields. It has been concluded that convection currents are developed at the interface between iron and insulator regions.
