Moisture is one of the main enemies of an electric motor. It imperceptibly destroys the insulation and leads to breakdown. Let's look at the effect of moisture on the engine and methods of protection.
What harms moisture
- Reduces insulation resistance - current leakage appears.
- Causes breakdownof the winding on the housing.
- Provokes corrosionof the shaft, bearings, magnetic circuit.
- Washes out lubricantfrom bearings.
Where does moisture come from
| Source | Situation |
|---|---|
| Condensation | Temperature changes, downtime |
| Direct water ingress | Washing, flooding, precipitation |
| High environmental humidity | Pump rooms, basements, greenhouses |
How to protect
- Use motors with a high degree of protection (IP55+).
- Moisture-resistant impregnation at rewind.
- Anti-condensation heating for equipment that is idle.
- Regular measurement of insulation resistance.
What to do if it gets wet
If the engine gets wet, it cannot be turned on immediately. First - drying the windings with insulation monitoring. This often saves the motor without rewinding. If the insulation is not restored, a rewind is needed. The assessment is given by diagnostics.
