    Abstract: One-time, single-use sensor elements (22, 46) are provided for detecting the occurrence of predetermined conditions such as temperature and elapsed time-temperature. The sensor elements (22, 46) preferably comprise elongated, glass-coated, metal alloy, amorphous or nanocrystalline microwires (30, 48), which can be placed in a position to detect the predetermined condition of interest. An alternating magnetic field detector (28) may be used to continuously or periodically interrogate the sensor elements (22, 46) to determine if the predetermined condition has occurred. In one aspect of the invention, the microwires (30, 48) experience a change in configuration upon the occurrence of the predetermined condition, and have correspondingly different induced remagnetization responses. In another embodiment, a static microwire is provided having an initial bi-stable single domain; when a predetermined time-temperature condition is experienced, multiple domains are established in the microwire, and this can be detected by the detector (28).

    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 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.

    Abstract: Soft magnetic composites having a high compressibility and a high permeability are described. These two characteristics are obtained by combining high compressibility iron powder to high permeability powders. The iron powder is of a high compressibility and in a size range and proportion that results in a powder mass amenable to compaction by industrially viable and cost-effective compaction process such as uniaxial cold compaction. The high compressibility iron powder helps achieve high relative density and also allows easy path for the passage of magnetic flux.
