Abstract
A bulk amorphous metal magnetic component has a plurality of laminations of ferromagnetic amorphous metal strips adhered together to form a generally three-dimensional part having the shape of a polyhedron. The component is formed by stamping, stacking and bonding. The bulk amorphous metal magnetic component may include an arcuate surface, and an implementation may include two arcuate surfaces that are disposed opposite each other. The magnetic component may be 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 B, it may exhibit a core-loss less than 'L' wherein L is given by the formula L=0.0074 f (B)+0.000282 f(B), said core loss, said excitation frequency and said peak induction level being measured in watts per kilogram, hertz, and teslas, respectively.
