Angular dependence of magnetic properties of 2% silicon electrical steel

In this work, we studied the anisotropy of the magnetic proper-ties of a 2% silicon steel. Permeability, core losses, remanence and coercivity were analyzed in Epstein strips cut at 0 degrees, 15 degrees, 30 degrees, 45 degrees, 60 degrees, 75 degrees and 90 degrees from the rolling direction. Coercive force monotonically increased from 0 degrees to 90 degrees, accompanied with a remanence decrease. On the other hand,. a minimum in B-50 and B-25 was observed between 45 degrees and 60 degrees. This behavior can be explained by the steel sheet crystallographic texture, that shows a strong (110) [001] component, which develops the best properties in rolling direction (001) and is worse at 54 degrees, where < 111 > lies. Losses behavior is more complex. () 2001 Elsevier Science B.V. All rights reserved.
