BULK AMORPHOUS METAL MAGNETIC COMPONENT

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 50 Hz and 20,000 Hz. When the component is excited at an excitation frequency "f" to a peak induction level Bmax, it exhibits a core loss less than "L" wherein L is given by the formula L = 0.0074 f(Bmax)<1.3>+ 0.000282 f<1.5>(Bmax)<2.4>, said core loss, said excitation frequency and said peak induction level being measure in watts per kilogram, hertz, and teslas, respectively. 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.
