Electronics

Longitudinal critically refracted wave for residual stress assessment on a welded plate using 3D laser vibrometry

Local residual stresses, remaining in a material without any external load, generally result from manufacturing processes and associated deformations. Their characterization is important, as they can weaken the mechanical performance of the…

Characterization and Multiscale Modeling of the Magneto-Elastic Behavior of Galfenol

The properties of giant magnetostrictive materials (GMMs) in actuation, sensing, or energy harvesting applications are very sensitive to pre-stress levels. This work presents the experimental characterization of the magneto-mechanical behavior of…

Predictive sensitivity analysis of motor’s windings HF impedances

This paper describes a process in which high frequency (HF) differential-mode (DM) and common-mode (CM) impedances of a Permanent Magnet Synchronous Motor (PMSM) are predicted. These tools, using both 2D Finite Element Modeling (FEM) and Spice…

Modeling random conductor distribution in stator winding slots: impact on common and differential-mode impedances

This paper presents a unified methodology for modeling the Common Mode (CM) and Differential Mode (DM) impedances of a permanent magnet synchronous motor. It combines finite element (FE) modeling methodologies with Spice-type discrete-parameter…
