The frequency converter provides flexible motor control, but also creates special operating conditions. Let's look at recommendations for operating a motor from a frequency converter in order to extend its life.
Features of operation from an inverter
- Deterioration of cooling at low speeds.The standard fan blows poorly.
- Load on insulation.Pulse voltage with steep edges.
- Possible bearing currentsfor powerful ones machines.
Recommendations
- Independent airflow. For long-term operation at low speeds, use forced cooling.
- Reinforced insulation. When rewind under the frequency generator, use insulation that is resistant to pulses voltages.
- Correct setting.Set acceleration/deceleration and current limits.
- Shielded cableand proper grounding.
What proper operation gives
| Measure | Effect |
|---|---|
| Independent airflow | No overheating at low speeds |
| Reinforced insulation | Winding service life |
| Correct tuning | Soft operation, protection |
Motors operating from a frequency converter without taking these nuances into account are more likely to overheat and fail. When repairing an inverter, it is important to use the right materials. The condition will be assessed by diagnostics.
