Often times when I broach the subject of electric motor management with a potential customer I hear “we already have that”. I then ask them to explain to me what their motor management program consists of? Most of the time I get, “my motor shop stores my motors and when I have a motor fail, they send me another”. I then think to myself; “This is not motor management this is a motor hotel…” Motors are stuck on a shelf and held until they are needed.
When looking to upgrade or purchase a spare medium voltage or ANEMA (above NEMA) motor it can be very intimidating. You have different enclosures, bearing designs, accessories, and about 100 manufacturers that would love to sell you a motor. You will also need take a good look at the driven equipment and your plant equipment to see what issues this upgrade/spare motor may cause. Wouldn’t it be nice to send everything you need to one place and have them do all the work? But that isn’t always the case.
When you think about the processes you have in place at your facility that are designed to keep the operation running, the first thing that comes to mind is most likely the PM schedule. You go around monthly or so and check filters, oil levels, temperatures and other detectable signs of easy to remedy issues that are bound to arise. Beyond that, maybe you have a quarterly vibration route and are collecting data on the health of your machines. Usually, this data is worth the cost of the program when it is able to predict an impending failure that can then be repaired before it breaks down catastrophically. This is a solid cost savings and can be easily justified.
With springtime coming to an end it’s not too late to get some last-minute spring cleaning done in your storerooms. So here are three ideas for cleaning up and consolidating your spare motor inventory.
Many companies have spare electric motors in their warehouse in the event of a critical motor failure. Many times this can be an intelligent decision, allowing for quick change out in the event of a failure (or pending failure) or during a scheduled outage or shutdown.
As a motor repair facility and supplier of new motors you tend to get asked the question, do you offer storage for my spare electric motors? When deciding if you should move your spares you need to ask yourself a few questions about what you are currently doing in-house:
- Are these spares getting inventoried regularly?
- Are the shafts being spun regularly?
- Is the area clean of dust/debris?
- Are they stored in a temperature controlled environment?
- Are they stored seperate from a repair production area?
