- Abstract
In this study, a new soft magnetic composite (SMC) material design scheme was put forward. According to this design scheme, SMC with silicate glass insulation layers was prepared by powder metallurgy with nanometer glass powder and micron iron powder. It can be annealed at high temperature for reducing residual stress. The magnetic properties were good. The maximum permeability, saturation magnetic induction, residual magnetic flux density and coercivity were 467, 1.47 T, 1.25 T and 394 A/m, respectively. The core loss versus alternating magnetic field frequency showed linear growth. The core loss was 4.4 W/kg at an induction level of 1 T, 50 Hz.
