Abstract

Manufacturing processes, such as cutting, welding, or assembling originate mechanical and thermal effects that locally introduce residual stresses. Consequently, the magnetic material shows a decrease of magnetic permeability and an increase of hysteresis losses. The adoption of catalogue data for electrical machines simulation thus follows low accuracy of the results. This article deals with effective modeling of the degradation of relative permeability and iron losses in soft magnetic materials due to manufacturing processes. The degradation profile is assessed by means of experimental activity conducted on a set of ring samples where the damaged material has been removed through electrical discharge machining. The proposed modeling approach is particularly relevantwhen it is implemented in numerical simulation tools.
