Abstract :
This paper investigates the influences of bending stress and annealing on magnetic properties of grain-oriented electrical steel sheets. Grain-oriented electrical steel sheets under different levels of bending stress are measured. The actual wound core transformer model that applied those magnetic properties is analyzed. The influences of bending stress and annealing on the behavior of the flux of an actual wound core transformer made by rolling electrical steel sheets are verified.
