Study on electromagnetic characteristics of cylindrical hole defect in variable parameter traction motor shaft based on eddy current effect.

PubMed · 2026-01-01

This study has no connection to plant science. It investigates electromagnetic methods for detecting corrosion defects in locomotive motor shafts using eddy current testing and computer simulation.

Horizontal magnetic induction intensity peak spacing can quantitatively measure the diameter of cylindrical hole defects in motor shafts

Amplitude variations of both horizontal and vertical magnetic signals can qualitatively detect defect presence and estimate relative depth, up to a saturation threshold

Vertical magnetic induction intensity phase is insensitive to defect geometry and therefore not useful for characterizing defect shape
