PHM in Motor

PHM in Motor

Measured parameter (Falekas & Karlis, 2021)

• insulation testing (partial discharges)
• electrical testing (current spectrum)
• flux analysis (stray flux): richer harmonic content
• transient analysis
• steady-state analysis (FEM model)

New techniques such as (Lee et al., 2020):

• insulation testing
• airgap and stray flux monitoring,
• transient analysis,
• intelligent algorithms, and fault prognostics for improving the reliability of condition monitoring and for providing a clear course of action for maintenance
