Rotational magnetization in nonoriented Fe-Si steel under uniaxial compressive and tensile stresses

The influence of uniaxial mechanical stress on the magnetization processes and energy losses in nonoriented Fe-Si steels is investigated under alternating and circular rotational flux. The advanced waveform control and measurement technique allow creating any kind of magnetic flux from alternating in all directions to different elliptical and circular rotational flux. The study of rotational magnetization under uniaxial stress gives a new perspective on the change of anisotropy of the material due to applied compressive or tensile stresses, as well as plastic deformation. Due to the broad use of nonoriented steel under rotational magnetization and mechanical stress or deformation, the new study could have a wide practical application.
