181 Amorphous alloy stereo wound-core US13704725 2011-10-31 US08736415B2 2014-05-27 Kaixuan Xu; Xianqing Guo
The invention provides an amorphous alloy stereo wound-core, comprising three structurally identical amorphous alloy made square frames; the cross section of the sides of the frames is in an approximately semi-circular or semi-polygonal shape; the frames have semi-circular cross sections and uniform thicknesses; the vertical sides of every two adjacent frames fit together fixedly to form a core pillar, the horizontal sides of the frames form iron yokes; the cross section of each core pillar has a circular or regular-polygonal shape. With this structure, the magnetic conduction direction of the amorphous alloy is completely consistent with the magnetic circuit direction of the core, and its working vibration is small. This core structure guarantees balanced three-phase power supply and largely reduces the magnetic resistance and excited current. There is no seam in the amorphous alloy stereo wound-core, so there is no area with high energy consumption. In this way, the advantages of the amorphous alloy on high magnetic conduction can be fully realized; the loss caused by an air gap in a seam is minimized. On the basis of the very low no-load loss of the conventional amorphous alloy, the present invention can further reduce the loss by 20% or more.
182 DIE ASSEMBLY AND METHOD FOR MANUFACTURING WOUND MOTOR LAMINATED ARTICLE US14056679 2013-10-17 US20140139067A1 2014-05-22 Thomas R. Neuenschwander; Barry A. Lee
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.

185 Reactor Device US13810852 2011-07-06 US20130147596A1 2013-06-13 Kenji Nakanoue
A reactor device is provided with a yoke section incorporating an elliptical wire-wound iron core and an iron-core leg section having wire-wound iron cores stacked one on another. The reactor device may have significantly deteriorated magnetic properties due to an abnormal current caused by a magnetic flux developed in the leg section. The short circuit of the abnormal current is cut by providing a cut portion from the center of the end surface of a wire-wound iron core in the leg section to the outer shape thereof and then insulating the cut portion. Use is made of a fixture jig to maintain the shape of the iron core even after the iron core has been cut, and at a final stage, use is made of a band or tape for maintaining the shape. The band used for maintaining the shape is adapted to prevent a magnetic flux developed in the iron core from making one turn.

Magnetic flux in a magnetic flux distribution inside a wound iron core for a stationary apparatus is mal-distributed toward the inner periphery side where the magnetic path of a laminated magnetic steel sheet is short with respect to the total lamination thickness and magnetic resistance is small and the inner periphery side on which magnetic flux is concentrated has a high magnetic flux density and increased iron loss, and therefore magnetic steel sheets of different magnetic characteristics are disposed at an arbitrary lamination ratio to make uniform the magnetic flux distribution inside the same wound iron core. In order to make uniform the magnetic flux distribution inside the wound iron core for a stationary apparatus, such a structure is adopted that a magnetic steel sheet having a magnetic characteristic inferior to that on the outer periphery side is disposed on the inner periphery side having a shorter magnetic path and smaller magnetic resistance and a magnetic steel sheet having a magnetic characteristic superior to that on the inner periphery side is disposed on the outer periphery side having a longer magnetic path and greater magnetic resistance to thereby make uniform the magnetic flux distribution in a sectional area of the iron core.

An electromagnetic component is formed from a pre-form comprising layers of soft magnetic metal ribbon. Adhesive is applied to permeate the pre-form and is then cured. The bonded pre-form is placed within a milling assembly that supports and constrains the ribbon layers during a milling operation used to process the pre-form into an electromagnetic component shape. Optionally, the shape is thermally processed. The resulting electromechanical component has attractive soft magnetic properties, including low core loss, that render it useful as a component in electric motors and generators and static inductive devices operable at high excitation frequencies.
