- Abstract:
- This paper concerns effects of mechanical stress on soft magnetic silicon iron sheets subject to rotational magnetization (RM). RM is typical for armatures of rotating machines and for T-joint regions of transformer cores. In both cases, distinct mechanical stress may arise, e.g., from temperature changes or from clamping. Simulation of such magneto-mechanical conditions on a specifically designed test apparatus shows that tensile (or compressive) stress of several MPa intensity yields distinct effects on all three permeability, energy losses and magnetostriction.
