[15E-T16-16] A New Generation of Sustainable SMC Materials with Low Core Loss
キーワード：Soft magnetic composite, Electrification, Sustainability
Electrification pushes the agenda of soft magnetic material development, with increased demands on efficient low loss materials with minimal environmental impact.
Soft Magnetic Composites (SMC) challenges traditional magnetic material such as soft ferrites and electrical steels in applications with alternating magnetic fields. In comparison to those traditional materials, the relatively higher hysteresis loss limits wide application of SMC.
A new material has been developed, that combines an improved base powder and newly developed coating, into a product with lower hysteresis losses than any previous material and improved thermal durability.
This paper introduces Somaloy® 7P, discusses the effect of manufacturing process parameters, such as compaction pressure, heat treatment temperature and atmosphere, on component performance. The effects of operating temperature on component properties are investigated. Finally, benefits of lower core loss are demonstrated in some application cases.
