摘要： A ferromagnetic amorphous metallic alloy strip is annealed to minimize exciting power rather than core loss. The strip has an exciting power less than 0.5 VA/kg when measured at 60 Hz and an operating induction of 1.40 to 1.45 Tesla, the measurement being carried out at ambient temperature. Cores composed of the strip can be run at higher operating induction than those annealed to minimize core loss. The physical size of the transformer's magnetic components, including the core, is significantly reduced.
摘要翻译：将铁磁性非晶金属合金带退火以使激发功率最小化而不是铁芯损耗。当在60Hz测量时，该条具有小于0.5VA / kg的激励功率，并且操作感应为1.40至1.45特斯拉，测量在环境温度下进行。由钢带组成的铁心可以比较高的工作感应运行，而不是退火的铁心，以减少铁心的损耗。包括核心在内的变压器磁性部件的物理尺寸大大减少。

摘要： An amorphous metal stator for a high efficiency radial-flux electric motor has a plurality of segments, each of which includes a plurality of layers of amorphous metal strips. The plural segments are arranged to form a generally cylindrical stator having a plurality of teeth sections or poles protruding radially inward from the inner surface of the stator. In a first embodiment, the stator back-iron and teeth are constructed such that radial flux passing through the stator crosses just one air gap when traversing each segment of the stator. In a second embodiment, the stator back-iron and teeth are constructed such that radial flux passing through the stator traverses each segment without crossing an air gap.

摘要： A high efficiency electric motor has a generally polyhedrally shaped bulk amorphous metal magnetic component in which a plurality of layers of amorphous metal strips are laminated together adhesively to form a generally three-dimensional part having the shape of a polyhedron. The bulk amorphous metal magnetic component may include an arcuate surface, and preferably includes two arcuate surfaces that are disposed opposite to each other. 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=0.005 f (Bmax)1.5+0.000012 f1.5 (Bmax)1.6, said core loss, said excitation frequency and said peak induction level being measured in watts per kilogram, hertz, and teslas, respectively. Performance characteristics of the bulk amorphous metal magnetic component of the present invention are significantly better than those of silicon-steel components operated over the same frequency range.

摘要： An iron based, boron, silicon, carbon and chromium containing magnetic alloy having at least 85 percent of its structure in the form of an amorphous metal matrix is annealed at a temperature and for a time sufficient to induce precipitation therein of discrete particles of its constituents and to form an oxide layer on the surface of the matrix. The resulting alloy has decreased high frequency core losses and increased low field permeability; it is particularly suited for high frequency applications.
