    Abstract: A nanomagnetic structure and a method of fabricating a nanomagnetic structure. The nanomagnetic comprises two or more nanomagnetic material elements, each nanomagnetic material element having a respective predetermined geometric shape such that the nanomagnetic structure exhibits different stable ground states initializable by magnetic fields applied across the nanomagnetic structure in respective different directions; wherein the nanomagnetic material elements are disposed relative to each other such that the magnetic structure exhibits a difference in effective internal magnetic field strength between the different stable ground states. Advantageously, this variation in the internal magnetic field strength is the key for distinct dynamic response associated with the different magnetic ground states. Reconfigurable operation has been shown based on this magnetization dynamics in example embodiments.

    Abstract: A method for applying at least one magnet, a holding device for such a method, and an arrangement comprising a number of holding devices. The method is used for applying at least one magnet to a surface of a part made of a magnetic material. The at least one magnet is moved towards the surface of the part while being retained in the holding device using a retaining force, and a force of attraction that acts against the retaining force is substantially directed towards the part and is applied to the at least one magnet such that the magnet is transferred to the surface of the part as soon as the magnet has been moved towards the surface of the part so as to be at a certain distance therefrom at which the force of attraction exceeds the retaining force.

  • Patent number: 8747583
    Abstract: This invention is a manufacturing device for a permanent magnet disposed in a rotating electrical machine, in which a plurality of magnet pieces, each formed by being fractured and split along a notch groove, are aligned and joined to each other with an adhesive interposed between fractured surfaces. First pressing means for aligning the plurality of fractured and split magnet pieces with the fractured surfaces opposed to each other in a width direction by pressing from the width direction of the permanent magnet and second pressing means for aligning the plurality of magnet pieces in a thickness direction by pressing from a thickness direction of the permanent magnet are provided. Moreover, third pressing means for joining the opposing fractured surfaces of the magnet piece with the interposed adhesive by pressing the plurality of magnet pieces from a longitudinal direction of the permanent magnet is provided.

  • Publication number: 20140139067
    Abstract: A metal article, such as a stator core, is formed from a continuous strip of wound sheet stock material including winding slot cutouts. The winding slot cutouts are maintained at a substantially constant width throughout most of the radial extent of the winding slots in the finished article, except that one or more of the first and/or last wound layers (i.e., the radially innermost and radially outermost layers) may define winding slot cutouts that are wider than the other winding slot cutouts. Several radial layers may define cutout widths that are progressively expanded such that the resulting winding slot has terminal ends with edges that defining a stair-step profile that approximates a “radiused” or rounded edge. This rounded edge profile protects windings projecting radially into or outwardly from the winding slots near the edge of such slots.

  • Publication number: 20140126162
    Abstract: An improved low cost and highly consistent inductive apparatus. In one embodiment, the low cost and highly consistent inductive apparatus addresses concerns with so called conductive anodic filament (CAF) that occurs within these laminate structures by incorporating surface mountable chip chokes in the underlying circuit design, These conditions that result in undesirable CAF include high humidity, high bias voltage (i.e. a large voltage differential), high-moisture content, surface and resin ionic impurities, glass to resin bond weakness and exposure to high assembly temperatures that can occur, for example, during lead free solder bonding application. Methods of manufacturing and using the aforementioned substrate inductive devices are also disclosed.
