Fanuc servo motor repair is less expensive than Fanuc servo motor replacement. Only trained technicians should perform Fanuc servo motor repair. Trained technicians undergo unique testing procedures on Fanuc servo motors that are dependent to each servo motors’ model, features, operations, and prints. Trained technicians will have the ability to perform these procedures successfully. The first step of Fanuc servo motor repair is the inspection of equipment for cosmetic damage or missing parts. Trained technicians take this step to ensure a successful repair is possible before proceeding further. Taking digital photos of the servo motor prior to further processing is also suggested.

Servo Motor nameplate data and preventative maintenance info should be collected by the technician and safely stored for future reference. Once these initial steps are complete, the servo motor should be meter tested before test running on a control panel; Meter testing prevents further damage to parts, motor winding, and insulation. The servo motor should then be connected to a test stand to check EMF (electromagnetic frequency), encoder or resolver feedback, and commutation alignment; These standard tests are to ensure functionality once the motor is installed for production. Servo motors also need to be tested with an oscilloscope to create an operation print. Once an operation printout is generated, a technician will check for connection issues, magnet failure, and winding failure. Once this is complete, the trained technician will perform a 100% component test to the servo motor.

Once these steps are complete, the technician will make repairs to applicable parts and order replacement parts that cannot be repaired. Finally, the technician will reassemble the servo motor for final testing. During the final test procedure, technicians should connect the motor to an inverter, with and without a load. Running the servo motor on an inverter ensures complete functionality. Testing with an inverter also allows verification that the servo can operate at full voltage and withstand full load amps of motor specifications. Repair shops should work closely with all servo motor manufacturers. Working closely with servo motor manufacturers allows repair shops accessibility to servo motor data sheets, parts, and other valuable information. Repair technicians use data sheets to ensure that the servo motor performs equal to, or better than, the original manufacturer standards.

Most repair shops offering Fanuc servo motor repair do not even perform the repair in their facility. Instead, these repair shops outsource the repair to a third party such as Precision Electric. Most manufacturers don’t know that their repair center isn’t even performing the repair. This process ends up costing the manufacturer more money, time, and additional problems with their equipment. The best option for manufacturers is to send their Fanuc servo motor to the company that’s actually performing the repair. This will save the manufacturer money, time and ensure the best possible repair. Fanuc servo motor repair from Precision Electric is performed in house and includes a 12 month in-service warranty.
