There are many different pieces of equipment relied on more than others at your facility. In manufacturing, electric motors are the most critical equipment in the building. They not only drive your business; they are an essential part of almost everything that takes place. In fact, they may be one of the largest assets in any facility.
When working normally, motors add to the productivity and efficiency of your operation. The opposite is also true. When motors fail, they halt your process. Rising expenses occur each moment of downtime. Being reactive to motor maintenance costs you in more ways than one. Being proactive by taking a preventative stance, saves you in more ways than one.
Preventative Maintenance Benefits
Starting a program has three main benefits. A preventative maintenance program:
- increases motor efficiency
- decreases the possibility of downtime
- boosts your productivity.
Preventative maintenance is not the same tasks for each motor. Those tasks are unique for each one. Choosing the best method necessitates that you take all factors into consideration. In most cases, perform these routine maintenance procedures on a set schedule. Always follow the instructions from the manufacturer.
Lubrication: Improper lubrication is one of the biggest problems for any motor. It doesn’t matter if it is too much, too little, or the wrong kind, it leads to problems. These problems shorten the lifespan of the motor. Check the lubricant on a regular basis and change it when necessary. Check the lubrication more often if the motor functions in harsh conditions.
Cable Insulation: Test the cable insulation on a regular basis. There are many different types of tests available. These including insulation resistance tests or the more comprehensive, polarization index test. Breakdown of the insulation occurs for many reasons. These reasons include excessive vibration, electrical discharge, and contamination.
Infrared Scans: Infrared scans identify hot or cold spots in the motor that are a sign of trouble. After completing a scan, create a list that features general recommendations. Follow these recommendations each time there is an increase in temperature. Scan images show a thermographic test point area.
Vibration Analysis: Vibration analysis detects problems that you cannot see right now. Knowing these problems help you to make any adjustments needed before any major problems begin to occur.
Vibration analysis also alerts you to the fact that some repair is unavoidable. This lets you can schedule any downtime that’s necessary to avoid major setbacks. Besides, even though the problems are not evident, knowing about them is a benefit. Scheduling a time to repair or replace the motor is easier than dealing with sudden failures.
Motors are responsible for over 60% of all power consumed in the US manufacturing industry. Electric motors also represent a significant investment. When they fail, they cost you. When are inadequate, they affect much more.
