Overheating destroys the insulation and leads to engine combustion. But overheating is a consequence, and it is important to find the cause. Let's look at how to determine the cause of overheating.
Main reasons
- Overload - the engine pulls more than normal.
- Clogged ventilation - no heat removal.
- Phase failure - work on two phases.
- Interturn short circuit - local overheating.
- Low or high voltage.
- Frequent starts.
Step-by-step diagnostics
| Check | What it reveals |
|---|---|
| Phase current | Overload, phase loss, skew |
| Ventilation inspection | Contamination |
| Main voltage | Deviations |
| Thermal imager | Local overheating (turn short circuit) |
| Heating pattern | Uniform or local |
How to interpret
- Uniform overheating - overload or poor ventilation.
- Local overheating - interturn short circuit.
- Overheating + current imbalance - phase loss or turn short circuit.
It is important to eliminate exactly the reason, otherwise the overheating will return. If the reason is in the winding, you need rewinding, if it is external, you need to eliminate the overload or clean it. The exact cause is determined by diagnostics.
