What's the average lead time on electric motor repairs?
That question comes up often and can be difficult to answer. The lead time for a motor repair depends on several factors. If you want a repair that increases the reliability of your motor, it’s almost impossible to provide an accurate lead time estimate before knowing what actually is wrong with it!
Short Lead Times. Don't be Fool!
Short lead times for motor repair are attractive at first glance. You are losing money for every minute you don’t have a motor running. Even if you have a spare it still takes time to pull it, prep it, and install it. Getting a motor back in a couple of weeks as opposed to a month seems like a great idea.
A short average repair time isn’t always the best option.
A short lead-time should throw up a red flag if you’re interested in long-term reliability and performance. That estimate is likely based on what failed instead of why it failed -- and that can make a tremendous difference for the reliability of your motor.
Root Cause of Failure
Performing a quick repair that addresses the symptoms is different from troubleshooting until you find the root cause.
For example, suppose an anti-friction bearing has failed prematurely. But what caused that bearing to fail? There are quite a few reasons why bearings fail, such as lubrication problems, misalignment, corrosion, or overloading.
