Abstract

A high efficiency electric motor has a generally polyhedrally shaped bulk amorphous metal magnetic component (10) in which a plurality of layers (20) of amorphous metal strips are laminated together adhesively 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 to each other. The magnetic component is operable at frequencies ranging from about 50 Hz to about 20,000 Hz. When the motor is operated at an excitation frequency “f” to a peak induction level Bmax, the component exhibits a core-loss less than about 'L' wherein L is given by the formula L = 0.005 f (Bmax)1.5 + 0.000012 f1.5 (Bmax)1.6, said core loss, said excitation frequency and said peak induction level being measured in watts per kilogram, hertz and tesla, respectively. Performance characteristics of the bulk amorphous metal magnetic component of the present invention are significantly better than those of silicon-steel components over the same frequency range.
