Tip of the Week: Proper Motor Maintenance

Your focus should be on the most critical motors, not necessarily the ones most prone to failures.

How do you know you’re properly allocating motor maintenance resources? And what does proper allocation really mean?

If we begin with the premise that the purpose of motor maintenance is to prevent motor failures, then proper allocation means focusing resources on solving those failure causes that are the “heaviest.” This doesn’t necessarily mean the most frequent failure cause. For example, perhaps the critical motors are all lubricated by qualified lubrication techs. These motors simply don’t fail from lubrication problems. But the “qualified” limitation doesn’t apply to the other motors, so lubrication defects are common causes of failure.

Perhaps the failure of a critical motor causes a revenue loss of $250,000 an hour, and failure of a non-critical motor has a negligible effect on revenue. Allocating more resources to motor lubrication because it’s a frequent failure cause is a misallocation of resources away from the high-revenue critical motors.

In future tips, we’ll examine ways to properly allocate motor maintenance resources.
