POWER LOSS AND MICROSTRUCTURE IN NON-ORIENTED SiFe LAMINATIONS

Results are reported about the power loss dependence on microstructural parameters in SiFe non-oriented laminations.In particular, the direct influence of grain size and crystallographic texture on hysteresis losses is investigated.A general phenomenological law is provided, by which we are able to enucleate the individual effects of impurity content, average grain size and texture on losses.
