Abstract
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 Bthe unitary amorphous metal magnetic component has a core-loss less than 'L' wherein L is given by the formula L=0.0074f(B)+0.000282f(B), the core loss, excitation frequency and peak induction level being measured in watts per kilogram, hertz, and teslas, respectively.
