You had the motor repaired, it went back in, and a few months later it failed again. Production stopped for the second time, and now the question is whether the repair was wrong or something else is going on.
Why repeat failures happen
A repair fixes the damage. It does not always fix whatever caused the damage. If the cause is still there when the motor goes back into service, the same failure can come back.
Common contributors to motor failure include overheating, bearing wear, contamination, overload from the driven equipment, misalignment between the motor and what it drives, vibration, and problems with the supply or the drive controlling the motor. Often it is a combination, and the motor is simply where the problem shows up.
The cost of treating the symptom
Every repeat failure means another stoppage, another call-out and another repair bill. A repair that only addresses the symptom can turn into a cycle that costs more over time than finding the cause once.
What root-cause engineering looks at
Root-cause engineering starts from the failed motor and works outwards. It asks what condition the motor was in, what it was connected to, how it was driven and where it was running. The answer might sit in the motor itself, or in the gearbox, the drive, the alignment or the load.
That is why it helps to have one team looking across all of those areas, rather than one supplier for the motor and another for everything around it.
How EES Electro-Mechanical approaches it
At EES Electro-Mechanical, motor rewinds, gearbox refurbishment, drives and controls, and laser alignment are covered by one team. You deal with one point of contact, and one accountable engineer is responsible for each job. Our engineers look for the root cause as part of the work, so the repair addresses more than the symptom.
We offer a free assessment: we collect your motor, dismantle and inspect it free of charge, and give you a quotation before any repair. If you decide not to proceed, we return the unit free of charge.
Next step
If you have a motor that keeps coming back, tell us about it. See our Electric Motor Repairs and Rewinds page, or use the quote form to describe the problem.
