Experimental Measurements and Numerical Computations of a Ferromagnetic Core Made by Means of Additive Manufacturing.

This work presents experimental measurements and numerical computations about the magnetic behavior of a toroidal FeSi core made by means of additive manufacturing. The building technique of the sample is based on the laser bed powder fusion. The static hysteresis loops of the toroid have been measured for different magnetic inductions, and these data have been used to identify the corresponding Jiles-Atherton model parameters. The accuracy and reliability of this approach have been evaluated implementing the identified model in a finite element scheme. The numerical computations have been compared with the experimental data and an evaluation of the accuracy is given.
