Abstract Scope |
Cast resin-based cores have a few advantages over the sintered oxide-insulated SMCs despite having lower saturation and lower permeability. They can be freely designed and manufactured with almost no shape limitations. No compaction is necessary, thus stress-sensitive high-induction iron-based powders can be used as a magnetic material to increase the soft magnetic properties. The real challenge is to reduce the porosity of the cast or moulded cores, as pores are known to have a strong influence on the resulting SMC magnetic properties and its macroscopic cohesion as well. In this work we present our current results on optimization trials of such cores processing. By various technological treatments we were able to significantly reduce the porosity of cast SMC cores in shape of toroids from about 30 to only a few percent. This resulted in visible soft magnetic properties increase as well as power loss decrease. |
