Magnetic properties of hybrid-soft magnetic composites

Materials Science and Engineering: B, 2009
Abstract Soft magnetic composites containing an organic binder and mixtures of two different soft magnetic particles – iron and nano-crystalline Fe73.5Si15.5B7Cu1Nb3 – in varying mixing ratios have been prepared at a total filler fraction x mag = 0.5 and examined regarding the magnetic properties.

Soft magnetic composites in active magnetic bearings

IEE Colloquium on New Magnetic Materials - Bonded Iron, Lamination Steels, Sintered Iron and Permanent Magnets, 1998
Active magnetic bearings are being considered increasingly for high-speed electrical machines, since they eliminate frictional losses and are virtually maintenance-free. However, in addition to the copper loss in the coils, there may be a significant eddy current and hysteresis loss in the soft magnetic rotor.

High performance of Fe-based soft magnetic composites coated with novel nano-CaCO3/epoxy nanocomposites insulating layer

Journal of Solid State Chemistry, 2021
In this paper, a novel type of nano-CaCO3/epoxy nanocomposites insulating layer for the FeSiCr/carbonyl-iron soft magnetic composites (SMCs) has been successfully developed. The novel inorganic/resin nanocomposites can greatly reduce the core loss of the

The influences of matrix materials on the magnetic and mechanical properties of Fe78Si9B13 soft magnetic composites fabricated by injection molding

Materials research bulletin, 2021
Soft magnetic composites are fabricated via metal injection molding (MIM) of amorphous Fe78Si9B13 powder in which three kinds of binders (PA + SA, HDPE + SA, PA+HDPE + SA) are chosen as matrix materials. Because of the interaction between amino in PA and

Soft magnetic composite materials (SMCs)

Journal of Materials Processing Technology, 2007
Abstract Soft magnetic composites (SMCs), which are used in electromagnetic applications, can be described as ferromagnetic powder particles surrounded by an electrical insulating film. SMC components are normally manufactured by conventional PM compaction combined with new techniques, such as two step compaction, warm compaction, multi-step and ...

Permeability of hybrid soft magnetic composites

Acta Materialia, 2011
Abstract The magnetic permeability of a three-phase hybrid soft magnetic composite (SMC) is formulated, extending Eshelby’s equivalent inclusion method to account for the three-phase microstructure of this SMC. The composite contains two kinds of ellipsoidal fillers dispersed in a matrix. All of the components have distinct magnetic properties.
