Experimental determination of specific power losses and magnetostriction of electrical steel coils

Quantifying Effects of Cutting and Welding on Magnetic Properties of Electrical Steels

“…Such data are usually obtained from certificates or datasheets made available by electrical steel manufacturers using Epstein frame measurements [1], or in some cases from other methods [2]. The capability of any electrical steel manufacturer to reproduce the presented experiments since they have in-house Epstein frame measurements capabilities is a fundamental feature at the core of this paper.…”
