- •
A high-resolution spectral analysis is used for fault identification in an induction motor.
- •
The methodology uses the Empirical Mode Decomposition and a high-resolution method.
- •
The methodology could be applied during the start-up transient followed by a steady-state regime.
- •
The methodology identifies a single broken rotor bar and mixed eccentricity faults.
