Failures in a servomotor

Failures in a servomotor

A servomotor plays a crucial part in many operations and keeping it running is of utmost importance and the prevent faliures in a servomotors is crucial.

Downtime due to maintenance can be planned and scheduled without having a major impact on your business. But should your servomotor cease to function, the cost can be extraordinary.


Servo motors are critical for precise operation and movement to control your machines.

There are many types of failures that can occur in a motor, and we will discuss the most common causes that we see come through our repair shop below. In addition to the causes of failures, we offer potential solutions to help prevent or limit downtime. Understanding these types of failures can assist in improving the reliability of your servomotors.

So, it would be a shame if you landed with a failed servo. Not only because of the stoppage of the production lines and this scenario results in costly downtime.

Any servomotor will encounter problems after a while, but the more common problems can usually be handled if you know how to deal with them.

Some of the more common problems will happen regardless of maintenance or upkeep and may even cause a servomotor failure in the middle of an operation.

Before you begin disassembled the servomotor to inspect components, you’ll want to see if there’s a quick fix. Here’s a brief list of issues your team of maintenance might come across:


Do you know which are the most common reasons that can cause a servomotor breakdown?

1. Bearing failures.










2. Brake failures (burned, oil, grease etc)
















3. Broken magnets.











4. Mechanical binding faults, covers, axis.
























5. Internal contamination




































6. Damaged connectors.




















7. Winding Failure.















8. Electrical current / fluting (bearings – encoders).

9. Vibration

Dear readers ,

In the next few posts in our blog we will talk about bearing failures, brake failures, mechanical binding faults, covers, axis, winding failures, electrical current bearings  etc.
