Process For In-Line Mechanically Scribing Of Amorphous Foil For Magnetic Domain Alignment And Core Loss Reduction
The invention relates to the reduction of core losses in soft magnetic applications utilizing amorphous foil as the core material. Amorphous foil is known to have lower losses when compared to crystalline silicon steel laminations. It is found that a reduction of 10-40% of losses can be achieved over the current state of the art amorphous material by mechanical scribing of the surface of the soft magnetic laminations comprising the wound core in power conditioning devices such as a transformer. The scribing process introduces control of the magnetic domains causing ease of magnetic flux reversal.
