MAGNETIC-PROPERTIES OF THIN GAUGE 3-PERCENT SI-FE WITH (110)[001] ORIENTATION

Thin-gauge 3% Si-Pe with {110}[001] orientation is a suitable material for magnetic devices in the frequency range from 10(2) to 10(5) Hz, Low core loss and high permeability in this frequency range are required, With recently developed, highly grain-oriented materials, physical parameters that affect core losses were investigated as a function of excitation frequency and magnetic flux density. The relationship between core loss and excitation conditions is classified into four regions, This material is useful for transformers and inductors, especially for higher flux density application in the middle frequency region (Bm[maximum excitation magnetic flux density] > 1 T, 10(2) to 10(3) Hz), such as airplane devices.
