ALEXANDER MACHINERY Repair Services India

Yes. Synchronics operates India's largest industrial electronics repair facility in Vadodara, Gujarat with PAN-India courier pickup service from all major cities including Mumbai, Delhi, Bangalore, Chennai, Hyderabad, Pune, Ahmedabad, and Kolkata. We repair the complete Alexander Machinery portfolio — servo drives, proportional valve controllers, spindle drives, VFDs, and process automation modules. Typical turnaround is 5-7 days including parts sourcing.

Alexander servo systems are widely deployed in Indian textile looms and precision machine tools where encoder faults cause production line shutdowns. Synchronics maintains a dedicated test rig simulating rotary encoder signals to diagnose multi-channel feedback loss. We perform signal integrity analysis on encoder connectors, test incremental and absolute encoder protocols, and recalibrate position offsets to restore closed-loop stability. Our repair rate for encoder-related faults exceeds 94%.

Synchronics maintains factory-authorized parts inventory for critical Alexander Machinery components including IGBT modules, proportional solenoids, rotary encoders, thermal sensors, and electrolytic capacitor modules. We also source components directly from Alexander Machinery distributors in Europe within 48-72 hours for non-stock items. All replacement components carry original warranty and traceability documentation.

IGBT module replacement in Alexander spindle drives requires precision thermal interface material application and gate driver circuit testing. Synchronics uses temperature-controlled solder reflow for surface-mount components, applies Phase Change Material (PCM) thermal pads, and performs thermal cycling (-10°C to +55°C) on installed modules. We verify gate signal rise-time, switching frequency stability, and perform load testing at 110% rated current sustained for 2 hours before return.

Post-repair commissioning on Alexander equipment includes functional verification of all I/O channels, communication protocol testing (CANbus, Profibus, Ethernet), sensor calibration checks, and parameter backup documentation. For servo and spindle drives, we perform closed-loop stability tests, velocity ramping profiles, and sustained torque loading. All units are pressure and thermal cycled before release to ensure reliability in Indian industrial environments prone to power quality variations and temperature extremes.

Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.

Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.

All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.

Yes. If we cannot repair your ALEXANDER MACHINERY unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
