WEG Equipment We Repair — By Category
WEG Product Lines We Repair
Our engineers are trained on the full WEG product range. Below are the major product families we service.
WEG W22 and Premium Efficiency Motors
Three-phase induction motors ranging 0.12 kW to 375 kW, designed for continuous duty industrial applications. Common repair issues include bearing wear, stator insulation breakdown, shaft misalignment, and moisture ingress in tropical environments.
WEG CFW500 Variable Frequency Drives
Compact vector drive series (0.5 HP to 200 HP) widely used in Indian textile mills, sugar factories, and pump stations. Typical faults: capacitor degradation, IGBT module failures, control board component drift, and firmware corruption under industrial noise conditions.
WEG CFW1100 and CFW1200 Industrial Drives
Advanced VFDs for high-performance applications in cement mills, steel rolling, and marine propulsion. Repair complexity includes multi-axis synchronization, encoder interface problems, thermal runaway conditions, and power stage component replacement.
WEG Soft Starters SSW Series
Electronic soft starting devices (15 A to 3150 A) for controlled motor acceleration in crushers, conveyors, and compressor applications. Common failures: thyristor short circuits, phase loss detection circuit faults, cooling fan motor burnout, and current sensing errors.
WEG PLC and Automation Controllers
Programmable logic controllers and HMI terminals for process control and data acquisition. Repair involves memory chip replacement, I/O module isolation, power supply stabilization, and communication port restoration in high-humidity plant floors.
WEG Power Distribution and Capacitor Banks
Harmonic filtering units, reactive power compensation, and capacitor modules for power factor correction. Typical issues: electrolytic capacitor dry-out, thyristor bridge malfunction, cooling system inadequacy, and discharge resistor degradation.
Why Choose Synchronics for WEG Repairs?
PCB-Level Expertise
We repair down to the component level — not just swap boards. Our engineers identify root causes, replace failed IGBTs, capacitors, processors, and gate drivers on WEG equipment.
Fast Turnaround
Standard 7–10 working days. Express 3–5 days available for critical breakdowns. Emergency same-day/next-day service for unplanned downtime.
6-Month Warranty
Every repaired unit ships with a 6-month comprehensive warranty on parts and labour. Our repair success rate is over 94% across all brands.
All-India Service
Couriered repairs accepted from any city in India — Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common WEG Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in WEG equipment arriving at our workshop.
- ✓CFW500 IGBT module short circuit failure — Transient voltage spikes from unshielded motor cables, inadequate DC bus snubber design, or moisture intrusion into power module in humid Indian manufacturing environments. Overload conditions accelerate junction degradation.
- ✓W22 motor stator winding insulation breakdown — Sustained overload conditions in sugar crushers or cement mills, thermal cycling stress from frequent start-stop duty, contamination from airborne dust and moisture in tropical ambient, or inadequate ventilation blocking cooling airflow.
- ✓CFW1100 control board capacitor swelling and leakage — Ambient temperatures exceeding 50°C in non-air-conditioned pump stations and foundries, poor quality electrolytic capacitors from original assembly, and ripple current stress during continuous duty operation year-round.
- ✓SSW soft starter thyristor triggering circuit malfunction — Electromagnetic interference (EMI) from adjacent welding equipment or furnaces, damaged optocoupler gate drive isolation, ground plane separation on control PCB, or accumulated carbon residue in screw terminals.
- ✓WEG PLC memory and backup battery failure — Extended power outages causing backup battery depletion, corrosion of battery connector contacts from water vapor in food processing plants, or manufacturing defects in battery compartment sealing.
- ✓Motor bearing cage fracture and rotor rub condition — Misalignment with driven equipment (pump or fan shaft), inadequate lubrication intervals in remote locations, radial load concentration from single-sided coupling, or contamination of bearing grease by external particle ingress.

We offer pan-India pickup and delivery service from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, and all major industrial cities. All repair work is conducted at our Vadodara, Gujarat facility with 180+ trained engineers.
What is the typical turnaround time for WEG CFW500 drive repair?+
Standard turnaround is 5-7 working days from receipt, including diagnostic testing, component replacement, full bench validation, and documentation. Emergency same-day diagnostics are available for production-critical failures at sugar mills, cement plants, and water treatment stations. Express repairs with priority parts availability complete within 48-72 hours if stock components are required.
Can Synchronics repair WEG motors with custom winding configurations for specific applications?+
Yes. Our engineers restore WEG motors to exact original specifications including custom winding arrangements, pole configurations, and insulation systems. We maintain detailed technical records of winding patterns and perform precision resistance balancing. Each repaired motor undergoes no-load and full-load testing to verify performance matches pre-failure condition.
Does Synchronics provide warranty on WEG equipment repairs?+
All WEG repairs carry 12-month comprehensive warranty covering parts and labor against manufacturing defects and workmanship. We also offer extended warranty options (24-36 months) for critical production equipment. Warranty covers motor failure, drive malfunction, and control circuit faults; excluded items are customer-induced mechanical damage and improper installation.
Which WEG fault codes does Synchronics diagnose and repair?+
Synchronics diagnostics covers all CFW and SSW series fault codes including E1 (phase loss), E2 (overcurrent), E3 (overvoltage), E7 (thermal overload), E10 (encoder error), E15 (communication loss), and E20 (internal fault). Our technicians decode error logs, isolate root causes using oscilloscope analysis, and repair or replace faulty circuits. Documentation and clear fault history is provided with every repair.
How do I send my WEG unit for repair?+
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.
What is the cost of repairing a WEG drive or PLC?+
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.
What warranty do you provide on WEG repairs?+
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.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your WEG 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.
