“…However, these limitations were being overcome with the development of improved raw materials and new shaping technologies. These composites find increasing use in electrical motors, replacing existing laminate materials [53,56,59,65,[68][69][70][71][72][73]. These materials are being developed to provide materials with competitive magnetic properties (good relative permeability and magnetic saturation), but with high electrical resistivity [49].…”

“…Compared with the conventional laminated steel cores, SMCs offer enormous advantages, such as three-dimensional isotropic magnetic properties, low eddy-current core loss at high frequency, and high adaptability to complex machine design. Hence, it has replaced the laminated steel cores in most fields of electric motors, transformer cores, power switching inductors, online noise filters, and chokes [2][3][4][5].…”

An iron-based soft magnetic composite with Fe 3 O 4 -MnZnFe 2 O 4 insulation coating has been prepared by powder metallurgy method. This work investigated the microstructure and magnetic properties of Fe/Fe 3 O 4 -MnZnFe 2 O 4 powder cores. Scanning electron microscopy (SEM) coupled with an energy dispersive spectrometry (EDS) analysis indicated that the Fe 3 O 4 and MnZnFe 2 O 4 nanoparticles were uniformly coated on the surface of Fe powders. The co-existence of Fe 3 O 4 and MnZnFe 2 O 4 contributes to the preferable distribution of nano-sized insulation powders and excellent soft magnetic properties of soft magnetic composite (SMC) with high saturation magnetization M s (215 A·m 2 /kg), low core loss (178.7 W/kg measured at 100 kHz, 50 mT), and high effective amplitude permeability of 114 (measured at 100 kHz). Overall, this work has great potential for realizing low core loss and outstanding soft magnetic properties of Fe-based powder cores.

“…The engineering community has noticed the advantages resulting from the application of powder metallurgy in the design of electromagnetic converters and electric machines [11][12][13][14][15]. Insulated iron powder (compacted and heat treated) offers an attractive alternative to conventionally used steel laminations in components requiring soft magnetic materials.…”

Magnetic Properties of SMC Cores Produced at a Low Compacting Temperature

Soft magnetic composites are readily used in the design of electromagnetic converters and electrical machines. In the paper, the magnetic properties of "home-made" cores made of iron powder and suspense polyvinyl chloride are examined. Samples were prepared by hot pressing of a PVC/Fe powder mixture with a different ratio of constituent components. Phase composition was investigated using an X-ray diffractometer and the presence of α-Fe was detected. Measurements of magnetic permeability revealed its allometric decrease with an increase of PVC content in composite. For the description of magnetization curves the phenomenological Jiles-Atherton model is used. The results of simulations are in a qualitative agreement with experiment.
