Abstract

The effect of tensile stresses applied at magnetic fields H = 100–800 A/m on the magnetic properties of anisotropic electrical steels T130-27S and N27P-100 (PAO NLMK), B27P100 (BAO Steel), and H100-27 (Thyssen Krupp) has been studied. The application of external tensile stresses along the easy magnetization direction at magnetic fields H = 800 A/m and a maximum measurement induction of 1.7 T is shown to increase the magnetic induction up to 1.95 T and to decrease the specific magnetic losses by 19–26%. This effect is caused by the optimization of a domain structure. For the electrical steels under study, the application of external tensile stresses of 50–60 MPa is optimal, since the increase in the magnetic characteristics at higher stresses becomes insignificant and they can even decrease in some cases.
