Overheating is the number one enemy of motor windings. The cooling system is responsible for heat removal, and its condition directly affects the resource. Let's look at how ventilation and engine cooling are arranged.
How the engine is cooled
Most engines have a fan attached to the shaft that blows air over the ribs of the housing. The casing directs the air flow along the bed. This is how heat from the winding and bearings is dissipated into the environment.
What disrupts cooling
- Dust-clogged fins and channels are the main reason.
- Broken or dirty fan impeller
- Installation in a tight, unventilated place.
- Operation at low temperatures rpmfrom the frequency converter (the fan blows weakly).
How to avoid overheating
| Measure | Effect |
|---|---|
| Regular cleaning of fins and channels | Restoring the heat sink |
| Checking impellers | Normal airflow |
| Free space around | Air flow |
| Independent airflow when operating from the inverter | Cooling at low speeds |
When the engine is running from a frequency converter at low speeds, the standard fan cools poorly - in such cases an independent one is installed blowing Overheating quickly destroys the insulation and leads to rewind. Regular diagnostics and cleaning prevent the problem.
