4 things to consider for maintaining your frequency converter
In many industrial and commercial plants, the automation of any associated procedure and control relies heavily on motors and variable speed drives. AC variable speed drives have become the most popular variable speed control devices in this field as well as in residential applications
How to maintain your frequency converter?
Maintenance requirements for the adjustable frequency drive fall into some basic categories including:
- Motor check
You should check your electric motors before installing a variable frequency drive. This ensures that the motor is properly sized and operating efficiently.
- keep it clean
Dust on the hardware CA drive can cause lack of airflow, which results in moderate performance decrease of heatsinks and circulating fans.
Dust concentrates moisture on the electrical device, it may cause malfunction or even failure.
Sometimes spraying air through the heatsink fan is a virtuous defensive maintenance measure.
Installing compressed air in a variable frequency drive is a feasible option in some environments, but typical plant air includes oil and water. So when using compressed air for preservation, you must confirm that it is dry and oil-free, otherwise you may be doing more harm than good. You always follow the risk of generating electrostatic charges (ESD). A non-electrostatic vaporizer or reverse ESD dump will reduce static electricity buildup.
keep it dry
Corrosion produced by moisture on a circuit board can ensue at any time. In one case, a variable speed drive was wall mounted in a clean, dry area of a mechanical room and moisture was not an issue.
- Keep Connections Tight
Reviewing knowledge is a step that many miss or do wrong. Heat cycles and electrical vibrations can lead to substandard influences.
Overtightening bolts is not a good idea, and connections should only be retightened to the manufacturer’s recommendations once the assembly is established to be clean and burn-free.
Further shrinking of an already tight joint can destroy the connection. Poor connections lead to arcing which could lead to troublesome overvoltage faults, erased input fuses, or tampered with defensive components
