<P>PROBLEM TO BE SOLVED: 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. <P>SOLUTION: 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 (B<SB POS="POST">max</SB>)<SP POS="POST">1.5</SP>+0.000012f<SP POS="POST">1.5</SP>(B<SB POS="POST">max</SB>)<SP POS="POST">1.6</SP>. <P>COPYRIGHT: (C)2012,JPO&INPIT |
