Obsolete Servomotors

The servomotor is the backbone of all industrial manufacturing. It has revolutionized the way we make just about everything in an industrial environment. Servomotors convert small amounts of power into precisely controlled motion. When they operate properly, they provide us with dreamlike accuracy. When they fail, they can leave us hanging. However, obsolete servomotors open up a new page in the book of down-time.

Servomotor Troubleshooting

Fortunately, servomotor problems can be fairly simple to diagnose, sometimes the bigger issue is finding a suitable replacement for an obsolete servomotor in an environment of ever-changing technology and design.

For ease of use, accessibility, and available new and used servomotors, we've been referring individuals to eBay. It almost seems too easy, but we've found many parts available that we thought we'd never find. Even after checking with larger parts houses, we still come back and check here regularly. It is not unusual to find obsolete servomotors from Siemens, Mitsubishi, Allen Bradley, ABB, Fuji, GE, and many more.

These parts are those that were posted as a result of hard times or possibly excess parts inventory at other companies. In many cases, they are NOS (new old stock).

Machine downtime due to an obsolete servo motor is a reality for many. There are options, however, nothing is ever easy. Here is a systematic approach, a simple yet effective method in dealing with a failed component that has likely been phased out by the manufacturer and no longer readily available.

1. Identify your problem... Making a positive identification of the failed component is the crucial first step. Troubleshooting is not a synonym for guess-work. It is a scientific method of determining a problem. There should be no doubt as to the source of the problem. This is determined through testing and not guessing.

2. Check the shelf... That's right, all too many times has a spare component or unit been passed over and found a day late. It sounds simple, but it is always the next step. Don't go looking for something that doesn't need to be found.

3. Check with the manufacturer... A website visit, email, or quick phone call to inquire about a a drop-in replacement is common sense. This step will deliver the bad news if obsolescence is indeed the case.

4. Check eBay... Believe it or not, this has become somewhat of a flea market for old industrial parts. By many, it is still considered to be a website for collectibles and the like, but a quick search can actually reveal a different side to the 'bay. Many private sellers post industrial components as a buy it now type listing, therefore bypassing the auction format all together.

Take a moment and browse the eBay listings since they are always changing...

5. No positive results? explore other options... If your particular servo motor is ultimately deemed obsolete and unavailable, you'll need to take the next path of least resistance. This may be upgrade or update your equipment with newer components. The good news is that your machinery or industrial equipment will most likely not need complete re-engineering or a top-to-bottom overhaul to accomodate new components. Adjustments to your system are possible when there is no other choice.
