Abstract:

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.
