Specific power loss comparisons of magnetic strips using standard Epstein frame
MetadataShow full item record
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.
