SONNER MACHINERY CO.LTD Equipment We Repair — By Category
SONNER MACHINERY CO.LTD Product Lines We Repair
Our engineers are trained on the full SONNER MACHINERY CO.LTD product range. Below are the major product families we service.
Servo Motor Systems
High-torque servo motors used in packaging machinery and textile looms. Common issues include encoder failures, phase winding shorts, and bearing wear causing vibration and speed instability. Synchronics performs complete motor rewinding, encoder recalibration, and bearing replacement.
Spindle Drive Units
Variable-frequency spindle controllers for precision grinding, drilling, and milling applications. Failures often stem from capacitor degradation, power stage IGBT damage, and thermal runaway. Synchronics replaces electrolytic capacitors, tests IGBTs, and performs complete firmware diagnostics.
Motion Control Boards
PCB-based motion controllers and interpolators for multi-axis machinery. Board failures include solder joint cracking, memory IC failures, and connector oxidation. Synchronics offers PCB cleaning, component-level repair, and full functional testing.
Encoder and Feedback Systems
Absolute and incremental rotary encoders for position feedback. Common faults include optical element contamination, connector corrosion, and Hall sensor failure causing loss of position feedback and servo loop errors. Synchronics cleans optics, replaces connectors, and recalibrates encoder zero offsets.
Power Supply Modules
Regulated DC power supplies and auxiliary power boards for servo and drive systems. Failures include transformer winding burnout, rectifier diode shorts, and voltage regulation IC failure. Synchronics replaces transformers, diodes, and performs load testing.

Common SONNER MACHINERY CO.LTD Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in SONNER MACHINERY CO.LTD equipment arriving at our workshop.
- ✓Servo motor encoder zero drift — Prolonged vibration in textile looms and packaging lines causes encoder mounting bracket flex, shifting the optical reference. Sonner encoders are sensitive to this mechanical stress common in Indian mills running 24/7 shifts.
- ✓Spindle drive overcurrent shutdown — Sonner spindle drives trip on overcurrent when bearing wear increases friction or coolant contamination blocks spindle passages. High ambient temperatures in Indian factories accelerate capacitor aging, reducing drive thermal headroom.
- ✓Motion control board display freeze — Sonner MCB boards suffer display freezes due to corrupted flash memory from power fluctuations, a common issue in Indian facilities with unstable grid power. Connector pin corrosion also interrupts data lines to the LCD interface.
- ✓Servo drive thermal shutdown during peak load — Sonner servo drives overheat when cooling fan bearings fail or heatsink fins clog with textile dust and oil aerosol. Poor ventilation in Indian manufacturing plants accelerates heatsink fouling.
- ✓Intermittent phase loss in servo motor windings — Vibration and thermal cycling in Sonner motors cause inter-turn winding shorts that produce intermittent single-phasing. High humidity in coastal Indian plants accelerates motor insulation degradation.
- ✓Encoder connector pin oxidation and signal dropout — Sonner encoders use standard M12 connectors that corrode in humid environments typical of textile and chemical processing plants. Moisture ingress combined with salt air near coastal facilities accelerates oxidation.

Express courier pickup and delivery across India is available for an additional charge.
Can you repair Sonner spindle drives that are showing fault codes?+
Absolutely. Synchronics specializes in Sonner spindle drive fault code diagnosis and repair. We decode Sonner proprietary fault codes, perform component-level testing of IGBTs and capacitors, and reprogram the drive firmware if needed. Common Sonner spindle drive faults like OC (overcurrent), OV (overvoltage), and TH (thermal) errors are diagnosed and resolved. We provide a detailed repair report with all test results.
Do you offer on-site repair service for Sonner machinery at textile mills?+
Yes, Synchronics offers on-site emergency repair and troubleshooting for critical Sonner Machinery equipment at Indian textile mills, packaging plants, and manufacturing facilities. Our field engineers can perform encoder realignment, drive parameter adjustment, and basic component replacement on-site. For complex repairs requiring lab diagnostics, we arrange quick-turnaround door-to-door courier with loaner units when available to minimize downtime.
Are spare parts available for older Sonner Machinery servo and spindle models?+
Yes. Synchronics maintains an inventory of Sonner servo motors, spindle drives, power supply modules, and encoder systems covering models from 1995 onwards. For obsolete Sonner components no longer manufactured, we source compatible replacements or perform component-level repair and rewinding. We also reverse-engineer circuit boards and firmware when needed. Contact our parts team for specific model availability.
How do I send my SONNER MACHINERY CO.LTD unit for repair?+
