The 7 Most Common Servo Motor Faults
Servo Motor Faults, Errors and Troubleshooting
1. Servo Motor Overheating
Out of all servo motor faults, overheating is one of the most common. It can be caused by an overcurrent on the machine. You or your maintenance engineer should look at the mechanical binding, any brake issues or check for any signs of overloading occurrence. Those are your possible mechanical issues.
If it isn’t a mechanical issue, inspect the shaft of the motor and spin it to check for any bearing failures. You can also check the windings for any issues, such as contamination or for any signs of short circuiting.
To prevent servo motor overheating in future, you can:
• Regulate the heat better
• Use fans correctly and open, airy cabinets
• Replace old, worn components
• Turn the servo motor off occasionally to allow cooling down
If something has gone wrong and you can’t find/fix the servo motor issue, get in touch. We can carry out servicing, testing, standard repairs and emergency repairs.
2. Bearing Failure
If your servo motor is slightly older and not as frequently maintained as it should be, the issue could be with the bearing. It’s very common for worn, older or unlubricated bearing. The servo motor will likely be making a nose/whine if it is an issue with the bearing.
You can change the settings and parameters of the servo motor, which may resolve the issue. But, if that doesn’t work and the bearing issue is too far gone, you will likely need to replace it.
Do it sooner rather than later, as the faulty bearing could lead to a total motor failure. And then you’ll need a completely new servo motor.

Expect friction, which would cause underperformance and a lot of grinding. You may notice a screeching noise, so listen out for that. To solve this, you could disassemble the servo motor, clean and reassemble.
If you don’t have the facilities to carry this out, you can send it to one of our workshops and have the servo motor repaired and overhauled.
4. Setup Issue or Loss of Parameters
Get in touch and we can do this for you.
5. Electrical Issue
Our sister company, Kontroltek, can repair any industrial electronic issues for you. Get in touch with us and we’ll refer you, so you get a good price.
6. Overloading Issue
7. Winding Issue
At Kontrolmek, we offer repairs, rewinds and refurbishments for servo motors. If the motor is beyond repair, we source replacements for good prices.
There are a lot of things that can go wrong with servo motors. They’re kept in dirty, dangerous places, where temperatures can sometimes fluctuate and leaks may occur.
It’s important to maintain your servo motor as well as possible. But if there isn’t something you can handle, Kontrolmek engineers will be able to repair it.
