Abstract

The effect of effective rolling strain, in the range 0-0.147, on the core loss, hysteresis loss, eddy current loss, ac and dc permeabilities of a lamination steel has been investigated. It was found that both core loss and hysteresis loss increased with the square root of strain. However, eddy current loss decreased with increasing square root of strain. Both ac and dc permeabilities are inversely proportional to the square root of strain. These magnetic properties were closely related to the dislocation density and were explained by the model of domain-dislocation interaction
