For electrical applications that require low losses, especially at high frequencies, components made from soft magnetic composites (SMCs) can provide more design flexibility as they can often be designed smaller, lighter and cheaper, and can make integration with the surrounding system easier. Sintex will present its expertise in the design and manufacturing of SMC components.
The SMC material consists of very pure iron powder with a special surface coating on each particle. This electrically insulating surface ensures a high electrical resistance and the eddy current loss is almost negligible. The benefits of SMC increase with the magnetic frequency. At frequencies exceeding 200Hz, SMC exhibits lower loss than standard 0.5mm-thick laminated iron plates. This boosts the maximum power rating, lowers running costs and benefits the environment.
