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 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 “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. 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.
摘要翻译：高效率电动机具有通常为多面体形状的块状非晶金属磁性部件，其中多层非晶态金属条被层叠在一起以形成具有多面体形状的大致三维部分。块状非晶金属磁性部件可以包括弧形表面，并且优选地包括彼此相对设置的两个弧形表面。磁性部件可在约50Hz至约20,000Hz的频率范围内操作。当电动机以激励频率“f”运行到峰值感应电平Bmax时，该分量表现出小于“L”的磁芯损耗，其中L由公式L = 0.0074f（Bmax）1.3 + 0.000282 f1给出。 5（Bmax）2.4，所述铁损，所述激励频率和所述峰值感应电平分别以瓦特/千克，赫兹和特斯拉进行测量。本发明的块状非晶态金属磁性部件的性能特征明显优于在同一频率范围内工作的硅钢部件。
