Identification of Defects in the Magnetoelectric Ring Sensor using Spectral Analysis

Abstract

The paper discusses the method for detecting defects that may arise in the construction of ring-shaped magnetoelectric sensors. The approach is based on the amplitude and phase spectral analysis generated on the sensor’s output. The defect detection is performed using the Discrete Fourier Transform (DFT). The experiments covered two faults, related to the physical dislocation of the amorphous metal ribbon around the magnetic ring. Results show that it is possible to automatically locate particular defects in the electromagnetic sensor based on the input-output characteristic analysis.
