Core Loss Reduction In Electrical Steels Through Materials Processing, B. Verbrugge, David C. Jiles

Electrical and Computer Engineering Publications

Research has been conducted into the effects of laser scribing on the core losses of soft magnetic materials. Various types of lamination steels for use in electric motors and transformers were studied including iron based alloys containing carbon,silicon,nickel, and cobalt. The results show that the change in core losses for carbon,nickel, and cobalt alloys was small for the scribing conditions examined, but core loss reductions of up to 18% were achieved with iron–silicon alloys.
