Computation of Eddy Current Loss in a Ferromagnetic Core with Single Excitation

Abstract

The present analysis is concerned with the determination of the magnetic field distribution and eddy current loss in a heavy ferromagnetic core by linear theory. An analytical method is used to solve a simple one dimensional rectangular coordinate diffusion equation governing the H field using Robin boundary condition which is the combination of Dirichlet and Neumann boundary condition. For linear analysis, different choices of Permeability are chosen to compute eddy current loss and the results are compared with the experimental value.
