Manipulation of stator current signature for rotor asymmetries fault diagnosis of wound rotor induction machine

In this paper, a new technique based on the manipulation of stator current signature for induction machines fault diagnosis is introduced. The goal proposed method to demodulate characteristic frequencies from supply frequency and preserve information its harmonics. can be easily implemented used in experimental systems due low computational complexity. validity proved through theoretical analysis results steady-state transient conditions. regard, 270-W wound rotor machine (WRIM) tested under different severities load levels.
