Servomotor repairs

You use it. We fix it.

We have been repairing servo motors for multiple CNC machines and different lines of production. Each servo motor goes into a controlled and rigorous process of inspection, repair and testing. Our certified technicians are always making sure that all components and tolerances respect the different OEM standards. All required machining and stator rewind are done in-house. A full one year warranty 24/7 and a control quality report come with all our repairs.

Common reasons for a servomotor breakdown

Bearings, electrical and winding failures
Positionning errors and overworking the motor
Damaged cables or connectors and internal contamination
Lack of preventive maintenance

Our repair process

Identification and preleminary testing of the servomotor
When we receive the servomotor, we do a complete analysis in order to identify the technical problems. We then dissasemble the product and measure each part in our metrology room by using high-end equipement. Components that are not following the manufacturer'specifications, are automatically machined.

problem and detailed quote
Once testing, measuring and assessment are done, a detailed quote with pictures showing all damaged parts, repair solutions and delays will be sent to the customer. As soon as it's aprproved, the magic will start!
Repair process
The repairs made on the servomotor may change depending the problems that were identified. This can includes in-house machining or grinding of spacers, bearing housing, bearing support, taper grind and more. Also, we replace OEM bearings, seals, o-rings, encoder and rotary union. If it is needed we wind the stator and we proceed dynamic balancing.
Final testing and quality control
At last, we assembly the servomotor and run it on one of our test benches for hours at full speed making sure all features are working well. It will be like if it was installed on a CNC machine. After, we test the encoder and resoler. All information related to repairs and tests will be included in the control quality report.

Analysis of the servomotor condition

During the preleminary testing, each servomotor is analyzed meticulously. Our technicians are proceeding various tests on it to detect possible problems. Doing that help us to understand better your servomotor condition and to propose you the solution that will bring it back at its initial state ! What we look ? Find below the complete list of the tests carried out by our experts .

What we are testing

• Verfication of the encoder, resolver or PLG alignment.

• Verification of the temperature at maximum speed.

• Analysis of the vibration level in mm/sec.

• Complete winding system analysis if required.
