    VFD & Servo Drive Repair

    Rapid repair of Variable Frequency Drives and Servo Amplifiers. We diagnose power stage failures and control board faults to get your motors turning again.

    Operational Impact

    IGBT/Power Stage Blowout

    Catastrophic failure of the power switching components.

    Overcurrent/Overvoltage Trips

    Drive constantly faults out due to internal sensing circuit failures.

    Dead Display/No Power

    Internal switch-mode power supply failure preventing the drive from booting.

    Capability

    Supported Infrastructure

    We provide component-level diagnostics and repair for a wide range of commercial and industrial electronics. If it controls critical infrastructure, we can likely repair it.

    • Variable Frequency Drives (VFD)
    • Servo Amplifiers
    • DC Motor Controllers
    • Soft Starters
    • Spindle Drives

    Engineering Workflow

    A structured, professional approach to returning your systems to full operation.

    01

    Initial Assessment

    Rapid evaluation of the fault and system impact.

    02

    Component Diagnostics

    Deep-level testing of electronic components.

    03

    Precision Repair

    Replacing faulty components and reinforcing weak tracks.

    04

    Testing & Handover

    Full load testing to ensure operational reliability.

    Why Repair Instead of Replace?

    OEMs often push for full system upgrades when a single electronic component fails. We offer a more logical, cost-effective alternative that keeps your existing infrastructure running.

    Minimize Downtime

    Repairing a board takes days; replacing a system takes weeks or months.

    Cost Effective

    Component-level repair is typically a fraction of the cost of full system replacement.

    Preserve Integration

    Avoid the need to reprogram or re-integrate a completely new system.
