To provide improved amorphous metal motor components that exhibit a combination of excellent magnetic and physical properties needed for high speed, high efficiency electric machines.
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 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=0.005f (Bmax) 1.5+0.000012f1.5 (Bmax) 1.6.
