A Multiscale Approach to Predict Classical Losses in Soft Magnetic 1 Composites
نویسندگان
چکیده
10 This paper presents the application of a finite element multiscale method, based on the homogenization technique, to the prediction 11 of classical losses in soft magnetic composite materials. The experimental results, obtained for a wide range of frequencies and for 12 various toroidal samples with different cross sections, are explained by using the considered model. It has been found that the classical 13 losses are influenced by the dimensions of the sample, as well as by the conductivity and the length of the random contacts between the 14 grains. 15 16 Index Terms — Composite materials, numerical analysis, multiscale problem, classical losses. 17 18 19

متن کاملLosses Approximation for Soft Magnetic Composites Based on a Homogenized Equivalent Conductivity
Soft magnetic composites (SMC) are a promising alternative to laminated steel in many Electrical Engineering applications. This is largely owing to their low level of eddy current losses. The electromagnetic behavior of SMC in electromagnetic devices cannot be easily predicted using standard numerical techniques such as the finite element method, mostly due to the computational cost required to...
