How condition monitoring techniques help you move from reactive repairs to predictive maintenance for motors and generators.
Many plants still rely heavily on run-to-failure or time-based overhauls for motors and generators. This often results in unexpected outages or unnecessary maintenance.
Condition monitoring uses measured data—vibration, temperature, electrical signals and process parameters—to assess equipment health in real time and predict issues before failure.
Vibration analysis to detect imbalance, misalignment, looseness and bearing defects.
Infrared thermography to identify hot spots on terminations, windings and bearings.
Online partial discharge monitoring for high-voltage stator insulation.
Electrical signature analysis to detect rotor bar issues, air-gap eccentricity and load-related problems.
Not every motor needs the same level of monitoring. Start with equipment whose failure would cause major production loss, safety risk or environmental impact.
Typical candidates include boiler feed pumps, ID/FD/PA fans, large mill motors, main cooling water pumps, propulsion motors and key compressor drives.
1. Define critical assets and current maintenance practices.
2. Select appropriate monitoring techniques for each asset type.
3. Establish data collection routes or online monitoring systems.
4. Train maintenance teams to interpret basic trends and partner with specialists for deeper diagnostics.
