Presentation / Conference Contribution
Bonet-Jara, J., Fernandez-Cavero, V., Vedreno Santos, F., & Pons-Llinares, J. (2022). Very Accurate Time-Frequency Representation of Induction Motors Harmonics for Fault Diagnosis Under Arbitrary Load Variations. In 2022 International Conference on Elect

Induction motors work under steady state in many applications. Nevertheless, in some cases (e.g., wood cutting machine or pulp mixer in paper industries), the load continuously varies. In these cases, time-frequency transforms are needed to detect th...
