Laminated amorphous metal component for an electric machine

A brushless, radial flux, permanent magnet DC motor comprising:

• a) an amorphous metal stator comprising a plurality of substantially similarly shaped layers which are stamped from ferromagnetic amorphous metal strips and stacked and bonded together in registry;
• and
• b) a rotor disposed for rotation within said stator, said rotor having at least one permanently magnetized region with at least one pair of oppositely magnetized poles.

A radial flux DC motor comprising:

• a) an amorphous metal stator having a plurality of substantially similarly shaped layers which are stamped from ferromagnetic amorphous metal strips and stacked and bonded together in registry, each layer including a plurality of tooth-shaped sections;
• and
• b) a rotor disposed for rotation within the stator.

A switched reluctance motor comprising:

• a) an amorphous metal stator having a plurality of substantially similarly shaped layers which are stamped from ferromagnetic amorphous metal strips and stacked and bonded together in registry, each layer including a plurality of tooth-shaped sections;
• and
• b) an amorphous metal rotor having a plurality of substantially similarly shaped layers which are stamped from ferromagnetic amorphous metal strips and stacked and bonded together in registry.

A bulk amorphous metal magnetic component for an electric machine comprising a plurality of substantially similarly shaped laminations of ferromagnetic amorphous metal, stacked and bonded together in registry, wherein the laminations include a plurality of tooth-shaped sections and said component when operated at an excitation frequency “f” to a peak induction level Bmax has a core-loss less than “L” wherein L is given by the formula L=0.0074 f (Bmax)1.3+0.000282 f1.5 (Bmax)2.4, said core loss, said excitation frequency and said peak induction level being measured in watts per kilogram, hertz, and teslas, respectively.
