Aspects of the cut-edge effect stress on the power loss and flux density distribution in electrical steel sheets
Review articleOpen access

AbstractThis paper describes some effects of cutting on power loss, localised flux distribution and B–H curves of a fully processed, high permeability non-oriented electrical steel. Cutting a single sheet into narrow strips increased the power loss by up to 30% and significantly changed the B–H characteristics. The change in flux distribution caused by cutting was lower when magnetised at 400 Hz than at 50 Hz.
