In this work, we detected the defects of the asynchronous electric machine under normal conditions and without load by installing multi-layer sensor active materials at the stator (Terfenol-D and PZT-5H). The magnetic field in the stator deforms the magnetostrictive layers and this distortion in turn affects the piezoelectric layer, which leads to the polarization of this layer and the appearance of a potential difference between their terminals. We chose the finite element method for the numerical solution. This method is a more powerful and versatile numerical technique for handling problems involving complex geometries and inhomogeneous media.

Abstract


In this work, we detected the defects of the asynchronous electric machine under normal conditions and without load by installing multi-layer sensor active materials at the stator (Terfenol-D and PZT-5H). The magnetic field in the stator deforms the magnetostrictive layers and this distortion in turn affects the piezoelectric layer, which leads to the polarization of this layer and the appearance of a potential difference between their terminals. We chose the finite element method for the numerical solution. This method is a more powerful and versatile numerical technique for handling problems involving complex geometries and inhomogeneous media.
