Abstract
A bulk amorphous metal magnetic component for an electric machine such as a motor or generator is described. The component may include a plurality of substantially similarly shaped laminations stamped from ferromagnetic amorphous metal strips, stacked and bonded together in registry, wherein the laminations include a plurality of tooth-shaped sections. In an alternate implementation, the component may be constructed by first stacking a plurality of layers of amorphous metal strips, laminating the layers and then cutting the object to form the component. The bulk amorphous metal magnetic component when operated at an excitation frequency “f” to a peak induction level B has 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.
