A unitary amorphous metal magnetic component for an axial flux electric machine such as a motor or generator is formed from a spirally wound annular cylinder of ferromagnetic amorphous metal strips. The cylinder is adhesively bonded and provided with a plurality of slots formed in one of the annular faces of the cylinder and extending from the inner diameter to the outer diameter of the cylinder. The component is preferably employed in constructing a high efficiency, axial flux electric motor. When operated at an excitation frequency “f” to a peak induction level Bmax the unitary amorphous metal magnetic component 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, the core loss, excitation frequency and peak induction level being measured in watts per kilogram, hertz, and teslas, respectively.
A low core-loss unitary amorphous metal magnetic component for an axial-flux electric machine, comprising:
An axial flux electric motor, comprising at least one low core loss, unitary amorphous metal component, said component comprising:
A brushless, axial flux, permanent magnet DC motor, comprising a frame, a unitary, low loss amorphous metal stator fixedly connected to said frame, and a permanent magnet rotor rotatably mounted in said frame, said rotor having at least one permanently magnetized region with at least one pair of oppositely magnetized poles, and said stator comprising:
An axial flux induction motor, comprising a low core-loss, unitary amorphous metal stator, said stator when operated at an excitation frequency “f” to a peak induction level Bmax having 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.
