  • Bifilar layer-insulated magnetic core and method for the production of a wound nanocrystalline magnetic core
    Patent number: 11170934
    Abstract: A method is provided for the production of a wound nanocrystalline magnetic core in which a nanocrystalline metal strip made of (Fe1-aMa)100-x-y-z-?-?CuxSiyBzM??X? is pre-wound to form a first coil. An insulating foil is provided that is coated with an adhesive on at least one side. An adhesive is applied to the nanocrystalline metal strip to laminate the insulating foil onto the metal strip and thereby to stabilise the metal strip as it is wound off the coil. The laminated nanocrystalline metal strip and the insulating foil are bifilar wound to form a bifilar, layer-insulated coil.

  • Method for producing nanocrystalline magnet cores, and device for carrying out said method
    Patent number: 7964043
    Abstract: The invention relates to a method and to a device for carrying out a manufacturing process in which all magnet cores to be produced are first continuously crystallized. Depending on whether the required hysteresis loops should be round, flat or rectangular, the magnet cores are either immediately finished, that is enclosed in housings, conditioned to a rectangular hysteresis loop in a direct-axis magnetic field or to a flat hysteresis loop in a magnetic cross-field and then finished.
