    摘要： An electrical choke comprises a magnetic amorphous metal core having, in combination, a distributed gap and a discrete gap. The amorphous metal is an iron based, rapidly solidified alloy. The distributed gap configuration is achieved by subjecting the magnetic core to a heat treatment, causing partial crystallization of the amorphous alloy. Such partial volume crystallization reduces the permeability of the magnetic core from several thousands to a value ranging from 200 to 800. The discrete gap is introduced by cutting the core and inserting a spacer. Depending on the width of the gap and the value of the annealed permeability, effective permeabilities in the range of 200 to 40 can be achieved. Advantageously, the reduced permeability magnetic core maintains its initial permeability under DC bias field excitation and exhibits low core loss, making it especially suited for use in power factor correction applications.

    摘要： The invention relates to an inductive component that comprises a magnetic core (1), coil (6) and yoke (7, 10). According to the invention, the magnetic core (1) comprises a cylinder (2) that has been wound from wide strip material around a non-magnetic material (5) such as to obtain planar outer ends (8, 9). Two flanges (3, 4) are wound from two narrow strips at the outer ends (8, 9) of the cylinder. The coil (6) is wound around the centre part of the cylinder (2) between the flanges (3, 4). Finally, the yoke (7, 10) is wound from strip material around the magnet core (1).

    摘要： A method for manufacturing a laminate comprising at least two sheets of magnetic material is disclosed. The laminate (10) may be used to form a stacked transformer core. The method increases the productivity of the core-stacking process, decreases the core loss destruction factor, decreases total core loss, decreases acoustic noise generated by the electrical device employing the laminate, and does all of this in a manner which is commercially practical. The method comprises applying an adhesive (12), preferably a hot melt adhesive, in a pattern of thin beads onto one side of a first lamina or sheet of magnetic material, the pattern comprising a plurality of lines, the lines being substantially parallel to each other and substantially perpendicular to a direction of grain orientation or rolling direction of the lamina. A second lamina is then stacked onto the one side of the first lamina, and then a compressive force is applied to specified areas of the laminate. The spacing between the respective lines of adhesive is preferably 1-20 millimeters and, for an approximate diameter (D) of each bead, the spacing (S) between the beads of each line is preferably between D and 2D.
