Amorphous alloy stereo wound-core
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.
