Alloy Powder Core for EV

Alloy Powder Core for EV

Alloy Powder cores are made of “iron alloy” powders mixed with epoxy resins, which is compressed at high pressure to form toroids, pot cores etc. Their permeability ranges 10 to 600 and saturation flux density ranges 0.7 to 1.6 T. They are mainly used in inductors and transformers in power electronics industry.

G&M is able to customize the design to meet customers’ requirements.

Alloy Powder cores are made of “iron alloy” powders mixed with epoxy resins, which is compressed at high pressure to form toroids, pot cores etc. Their permeability ranges 10 to 600 and saturation flux density ranges 0.7 to 1.6 T.  They are mainly used in inductors and transformers in power electronics industry.

Of these, MPP (made from 80% Ni Steel powders)  offer lowest core losses, but has lower flux capacity (Js ~0.75T).  Koolmu also offers competitively low core loss. Xflux (made from high Si steel) has the highest saturation flux density (Js~ 1.6T), but produces highest losses. Amoflux (made by powdering Metglas ribbon) offers 50% lower loss than HiFlux (made from 50% Ni Steel).   Most alloy powder cores can operate up to 200 C, excepting Amoflux which is limited to 155
