Challenge of PHM in Motor

Challenge of PHM in Motor

Challenge on PHM (Falekas and Karlis 2021)

• accurate CM ⭢ depend on models: productive algorithm need good model
• in PHM with AI techniques ⭢ depend on data quality produced: as methodologies largely depend on accurate values to produce acceptable results.

Limitation on PHM on Electric Machinery

• false indications,
• low sensitivity,
• difficulty of fault interpretation
• difficulties that arise from variable frequency drive (VFD) operation with the increase in the number of inverter-fed motors.
