Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
Bearing failure
Cause: Lubrication breakdown due to contamination, overgreasing, or thermal degradation leading to metal-to-metal contact and eventual seizure
Winding insulation breakdown
Cause: Thermal overload from excessive current, voltage imbalance, or poor ventilation causing insulation degradation and short circuits
Maintenance Indicators
  • Abnormal high-pitched whining or grinding noise from motor housing indicating bearing wear
  • Excessive vibration or visible wobble in motor shaft during operation suggesting imbalance or misalignment
Engineering Tips
  • Implement precision laser alignment during installation and re-alignment after maintenance to reduce bearing loads and vibration
  • Establish infrared thermography monitoring program to detect abnormal heat patterns in windings and bearings before catastrophic failure
