摘要: Magnetic permeability and losses at 1.5 T of a 2% Si non-oriented fully processed electrical steel Epstein strip, cut by different techniques (punching, guillotine, laser photocorrosion), have lower values the as-cut condition, when compared to after annealing. Permeability showed be more affected cutting than losses. Photocorrosion is slightly less harmful, but annealing did not improve it as much samples with guillotine.
