Electrical causes of damage
- Overvoltage and unstable supply voltage
- Insulation damage
- System overload
- Short circuits
Electrical problems often lead to permanent winding damage and the need for a complete motor overhaul.
Mechanical causes
- Worn or damaged bearings
- Unbalanced rotor
- Improper shaft alignment
- Excessive axial load
Mechanical failures often develop gradually and can be detected through vibration analysis.
Impact of the working environment
An industrial environment with high levels of dust, moisture, or chemical vapors accelerates wear and insulation degradation.
Conclusion
Regular electric motor maintenance and preventive inspections significantly reduce the risk of serious failures and costly interventions.
