Smoke from an electric motor is a clear signal of an accident. If the engine smokes, it means that the winding insulation is already being destroyed. Let's look at the reasons and the correct actions.
Why the engine smokes
- Winding combustiondue to overload or phase loss.
- Interturn short circuit - local overheating with smoke.
- Insulation breakdownon the housing.
- Stucking - a sharp increase in current and heating.
Smoke is the burning insulating varnish and enamel of the wire. You cannot continue working.
What to do immediately
- Immediately disconnect the engine from the mains.
- Do not try to start it again.
- Let it cool, check the free rotation of the shaft.
- Measure the insulation and winding resistance.
What expect
| Situation | Solution |
|---|---|
| Winding burned out | Rewind |
| Stuck | Replacing bearings |
| Partial damage | Depends on diagnostics |
If smoke starts, the winding will almost always need to be rewinded. But the sooner you turn off the engine, the higher the chance of preserving stator iron and reducing the cost of repairs. An accurate assessment is provided by diagnostics.
