Abstract
In this work, six different series of iron based soft magnetic composites are produced and studied: (1) passive iron powder; (2) passive iron powder-0.7% resin with coupling agent; (3) passive iron powder-0.7% resin without coupling agent; (4) passive iron powder-1.5% resin with coupling agent; (5) passive iron powder-1.5% resin without coupling agent; (6) pure iron-1.5% resin. The specimens were shaped as cylindrical rods and characterized by fourier transform infrared spectrometer (FTIR), energy dispersive analyzer (EDX), X-ray diffraction (XRD) and indutance capacitance resistance (LCR) meter. The results show that the hysteresis loss coefficient is close to each other for all the samples (0.0011 < k 2 < 0.0019), but the eddy current loss coefficient is higher for the passive-0.7% resin sample without coupling agent ( k 3 = 0.005) in comparison with the other samples.
