Problems solved by technology

However, Japanese Publication No. 04-165607 only teaches about simple shapes, which cannot create alignment between parts and control the inductance of the final assembly
The air gap formed by the bondline blocking the length of the magnetic path is uncontrolled and will result in an undesired height variation in inductance from component to component

Embodiment Construction

[0047] Except in the operating examples, or unless otherwise specifically stated, all numerical ranges, amounts, values ​​and percentages, such as those expressing amounts of materials, times and temperatures of reactions, ratios of amounts, and in the following sections of this specification Other parameters may be read as preceded by the word "about", even though the term "about" may not be explicitly presented with a numerical value, amount or range. Accordingly, unless indicated to the contrary, the numerical parameters set forth in the following specification and appended claims are approximations that may vary depending upon the desired properties sought to be obtained by the present invention. At any rate, and not as an attempt to limit the application of the doctrine of equivalents to the scope of the claims, each numerical parameter should at least be construed in light of the number of reported significant digits and by applying ordinary rounding techniques.

Abstract

Electromagnetic assemblies, core segments that form the same, and their methods of manufacture. The segments have an interlocking engagement, whereby a variety of assemblies can be produced from a very small number of similar or complementary segments in a manner that provides excellent mechanical stability. The articles and methods of formation offer design flexibility and provide for a large variety of patterns from a small number of primary shapes, provide an economical manufacturing method for large transformer and inductor cores, and improve uniformity of magnetic properties of the assemblies when compared to conventional practices.

Description

technical field [0001] The present invention relates to an electromagnetic assembly, coresegments forming the same, and methods for their manufacture. Background technique [0002] From ceramic materials, such as Mn-Zn ferrite, Ni-Zn ferrite and other soft magnetic ferrite compositions, and from powdered metal alloys, such as Fe, Fe-Al-Si, Fe-Co, Fe-Co Soft magnetic cores made of -V, Fe-Mn, Fe-P, Fe-Si, Ni-Fe, Ni-Fe-Mo and other soft magnetic alloys have been commercialized for decades. More recently, amorphous and nanocrystalline soft magnetic alloys made by various rapid solidification techniques and reduced to powder form by atomization or pulverization have also become commercially available. Single-piece cores, such as toroidal cores (rings), are available in sizes up to about 150 mm diameter. Sizes in excess of 150mm diameter are not economical to produce as very large high tonnage presses are required to consolidate the ceramic or metal powder into the desired shape...
