Abstract The most important properties of soft magnetic materials are peak induction and magnetic losses, determining the size and efficiency of electric devices. Conventional soft magnetic materials are not suitable for the construction of miniaturized magnetic cores. Soft magnetic composites meet miniaturization requirements of electric and electronic devices. In this paper, magnetic losses in self-developed Fe-polymer composites are analyzed. The frequency dependencies of magnetic losses are measured at different level of maximum induction. The influence of Fe-grain size on magnetic losses is also discussed.

Energetic Characterization

In recent years, innovative magnetic materials have been introduced in the field of electrical machines. In the ambit of soft magnetic materials, laminated steels guarantee good robustness and high magnetic performance but, in some high-frequency applications, can be replaced by Soft Magnetic Composite (SMC) materials. SMC materials allow us to reduce the eddy currents and to design innovative 3D magnetic circuits. In general, SMCs are characterized at room temperature, but as electrical machines operate at high temperature (around 100 °C), an investigation analysis of the temperature effect has been carried out on these materials; in particular, three SMC samples with different binder percentages and process parameters have been considered for magnetic and energetic characterization.
