Iron Loss Model Assumptions In the design process of a machine the ability to predict the iron losses is essential. Naturally, this also applies when using SMC in the soft magnetic parts. The total iron losses are basically divided into hysteresis-, eddy current- and anomalous losses according to the general equation: Pt = Ph + Pe + Pa (1)

WebA hysteresis loop shows the relationship between the induced magnetic flux density (B) and the magnetizing force (H). It is often referred to as the B-H loop. The area of a hysteresis loop varies with the type of material. The area, and thus the energy loss, is much greater for hard materials than for soft materials. WebOur range of soft magnetic materials comprises nickel-iron, silicon-iron and cobalt-iron alloys, as well as amorphous and nanocrystalline alloys. Thanks to their high magnetic saturation of up to 2.4 T, the cobalt-iron (CoFe) alloys VACOFLUX ® and VACODUR ® are generally suitable for all applications where high flux density
