Abstract
A magnetic core for use with electrical windings characterized by a plurality of groups of butt-jointed laminations of high permeability, amorphous material with each lamination group having a layer of protective material surrounding the outermost lamination and comprising a strip of material having a melting point above the temperature range of from about 340.degree. C. to 420.degree. C., whereby each lamination group is protected from damage during handling.
Claims3
A magnetic core for use with electrical coils comprising:
- a plurality of groups of butt-jointed laminations of an amorphous alloy having high permeability and brittleness as annealed,
- each group of laminations comprising an external layer of protective material having a melting point above the temperature range of from about 340.degree. C. to about 420.degree. C. and having high permeability in the direction of grain orientation, whereby each lamination group is protected from damage during handling, and
- the assembly of the laminations of amorphous metal an external layer being in surface-to-surface contact and devoid of interlaminar compounds.
