Fault diagnosis is currently a target of wide research activities. There is large number of diagnostic methods based on various source of diagnostic signal, signal processing and data evaluation approach. Stator current is traditional diagnostic signal for fault detection of induction machines. Monitoring of this signal is mainly effective in case of diagnosis of broken rotor bars and rings. However, analysis of external magnetic field appears to be more powerful in case of rotor eccentricity detection. The measurement system based on LabVIEW platform is now presented and it includes both stator current and external magnetic field analysis.
