BULK AMORPHOUS METAL MAGNETIC COMPONENTS

摘要

A bulk amorphous metal magnetic component has a plurality of layers of amorphous metal strips laminated together to form a generally three-dimensional part having the shape of a polyhedron. The bulk amorphous metal magnetic component may include an arcuate surface, and preferably includes two arcuate surfaces that are disposed opposite each other. The magnetic component is operable at frequencies ranging from between approximately 60 Hz and 20,000 Hz and exhibits a core-loss of between less than or equal to approximately 1 watt-per-kilogram of amorphous metal material for a flux density of 1.4 T and when operated at a frequency of approximately 60 Hz, and a core-loss of less than or approximately equal to 70 watts-per-kilogram of amorphous metal material for a flux density of 0.30T and when operated at a frequency of approximately 20,000 Hz. Performance characteristics of the bulk amorphous metal magnetic component of the present invention are significantly better when compared to silicon-steel components operated over the same frequency range.
