Abstract
Changes in permeability and magnetic losses in non-oriented electrical steel sheets resulting from compressive stress have been investigated using a single-sheet tester. A compressive stress of up to 20 MPa is uniformly applied normal to the sheet surface. It is demonstrated that a stress beyond 5 MPa can decrease magnetic losses, including both hysteresis loss and eddy current loss.
