ABSTRACT:
A ferromagnetic amorphous metallic alloy strip is annealed to minimize exciting power rather than core loss. The strip has an exciting power less than 0.5 VA/kg when measured at 60 Hz and an operating induction of 1.40 to 1.45 Tesla, the measurement being carried out at ambient temperature. Cores composed of the strip can be run at higher operating induction than those annealed to minimize core loss. The physical size of the transformer's magnetic components, including the core, is significantly reduced.
