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.
Keywords: Magnetic losses, permeability, electrical steel, compressive stress
