Specific power loss comparisons of magnetic strips using standard Epstein frame

Abstract

Amorphous magnetic materials are now competing in some of the markets traditionally monopolized by electrical steels. A variety of grain-oriented silicon-iron and amorphous magnetic materials have been under investigation. In order to compare their magnetic properties: we have used an Epstein frame. The samples were magnetized over a range of flux densities from 0.7 T to 1.5 T at 50 Hz. Results show that Metglas 2605SC (Fe81B13.5Si3.5C2) amorphous material is superior to all silicon-iron electrical steels, except for some disadvantages for transformer use.
