Repair of servo drives and electric motors - service
Repair and maintenance of servo drives and electric motors
Electric motors are the “muscles” of every robot. We know that when it comes to servo drives, there can be no compromise on motion precision and torque stability. We specialize in the advanced refurbishment of servo drives and electric motors used in robotics and industrial automation, restoring them to full factory performance.
Full range of electric motor repairs
We repair motors for robots manufactured by ABB, Kuka, Fanuc, Yaskawa, Reiss, and Hyundai Robotics.
We also repair other specialized drives used in robots and industrial equipment:
- Diagnostics and calibration of feedback systems: Alignment of incremental and absolute encoders and resolvers. We have specialized equipment for synchronizing the measurement system with the rotor’s magnetic field
- Mechanical system service: Replacement of high-precision bearings (designed for operation at high temperatures and high rotational speeds), reconditioning of shaft journals and bearing seats.
- Brake system reconditioning: Air gap inspection, holding torque measurement, and replacement of friction linings in safety brakes; we plan and fabricate replacement brake discs
- Winding diagnostics: Insulation resistance measurements, voltage tests, and winding continuity testing using impulse testers, which allows for the detection of inter-turn short circuits invisible to a standard multimeter
- Comprehensive reconditioning and cleaning of all components
Testing Laboratory and Inspection
Every motor undergoes rigorous final testing after repair to ensure it can be safely installed on a machine:
- Dynamic tests: Motor operation controlled by a dedicated inverter across the full speed range.
- Torque testing: Checking braking torque and operation under load.
- Endurance tests: Extended testing at full speeds and under full load.
- Electrical measurements: Inspection of winding insulation and electrical systems.
Comprehensive services and warranty
We provide technical support and troubleshooting services for industrial robots.
We can perform on-site diagnostics of the robot and safely remove the motor—while maintaining the calibration of the entire robot.
We can install a new part in place of the damaged one and take the damaged part for refurbishment. A comprehensive repair of a robot or machine performed by our company guarantees that the robot’s calibration and settings remain intact. We handle repairs at every stage of this process.
We provide a warranty for repairs and work performed.
