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.

  • Our repair process

    Preliminary testing
    At arrival, a complete analysis is performed to identify mechanical and electrical problems. The main tests proceeded are the analysis of the encoder, resolver and vibration.
    Dissasembly and diagnostics
    Once tested, the spindle is completely disassembled. Furthermore, parts are cleaned and inspected to see if they are damaged.
    Dimensional Measuring and Electrical testing
    Measuring of all precision components performed in out metrology room along with stator testing and electrical components testing. When evaluation is completed, a detailed quote showing damaged components, repair solutions, and lead time will be sent to customer.
    Repairs / Assembly
    In-house machining, grinding, taper grinding is performed if needed, before assembly can begin. New replacement parts to OEM specs are used: bearings, seals, o-rings, encoder, and rotary union, etc. Rewinding of stator if needed and dynamic balancing.
    Final Testing
    The servomotor is tested on one of our test benches up to full speed making sure temperatures, vibration, and all features are working correctly.
    Quality Control
    All servomotors must pass a final quality control inspection before proceeding to shipping.

    Analysis of the servomotor condition

    During the preliminary testing, each spindle is analyzed meticulously. Our technicians are doing various tests on it to detect possible problems. Doing that helps us to understand better your spindle condition and to propose you the best solution.

    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.
