STOBER Equipment We Repair — By Category
STOBER Product Lines We Repair
Our engineers are trained on the full STOBER product range. Below are the major product families we service.
STOBER Servo Drives and Frequency Converters
Variable frequency drives and servo controllers for STOBER motor-gearbox units, handling speed regulation and torque control in textile, cement, and packaging machinery. Common faults include capacitor failure, IGBT burnout, and encoder signal loss.
STOBER Helical Gearboxes with Integrated Motors
Compact helical gearbox units with direct-coupled electric motors used in conveyors, mixers, and extruders across Indian process industries. Repair focuses on gear wear, bearing failure, oil seal degradation, and motor winding breakdown.
STOBER Electromagnetic Brakes and Brake Motors
Spring-applied electromagnetic brakes and brake-equipped motors for safety-critical applications in cranes, hoists, and vertical conveyors. Failures typically involve brake coil burnout, spring fatigue, and armature sticking.
STOBER Bevel and Worm Gearboxes
Right-angle power transmission units for sugar mills, flour mills, and textile machinery where compact space and high torque requirements demand precision engineering. Common issues include gear tooth pitting, worm wear, and thrust bearing failure.
STOBER Modular Drive Electronics
Terminal boxes, junction blocks, and electronic control modules for STOBER drive systems used in multi-motor automation cells across Indian automotive and textile plants. Repair addresses connector corrosion, phase loss, and control signal degradation.

Common STOBER Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in STOBER equipment arriving at our workshop.
- ✓STOBER servo drive IGBT module thermal shutdown — Inadequate heatsink cooling in high-ambient environments (40-50°C in Indian summer) or fouled cooling fins from mill dust ingress. STOBER drives run hot under continuous load in textile and cement plants.
- ✓STOBER gearbox output shaft bearing preload loss — Inadequate lubrication combined with radial load from belt-driven pulleys causes angular contact bearing races to flatten. Common in Indian sugar mill centrifuge gearboxes operating 24/7 in humid, dusty environments.
- ✓STOBER electromagnetic brake coil insulation breakdown — Moisture absorption in brake coil insulation due to condensation and salt air corrosion in coastal Indian facilities (ports, chemical plants, saltworks). Brake coils rated 24VDC or 110VAC are particularly vulnerable.
- ✓STOBER frequency converter capacitor bank venting and swelling — High inrush currents in Indian industrial grids with poor power factor correction, combined with aged electrolytic capacitors (typically 8-12 year lifespan), cause electrolyte boil-off and internal pressure buildup.
- ✓STOBER motor encoder signal loss or quadrature error — Magnetic encoder sensors on STOBER servo motor shafts become misaligned or demagnetized due to vibration, thermal cycling, or direct exposure to external magnetic fields from nearby welding stations or induction heating equipment.
- ✓STOBER worm gearbox oil churning and overheating — Excessive oil fill level or use of wrong ISO viscosity (should be ISO 150-220 for STOBER worm units) causes viscous drag and heat buildup in Indian food processing and flour milling applications.

Frequently Asked Questions — STOBER Repairs
Do you repair STOBER equipment anywhere in India?+
Yes. Synchronics repairs the full STOBER product range — servo drives, frequency converters, motor-gearbox assemblies, electromagnetic brakes, and control electronics. We offer PAN India door-to-door pickup and return service from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, and all other major industrial cities. Repairs are completed in our facility in Vadodara, Gujarat.
What is the typical turnaround time for STOBER drive and gearbox repair?+
Standard STOBER repair (gearbox bearing replacement, brake coil change, capacitor bank swap) takes 5-7 working days once diagnostics are complete. Complex servo drive repairs involving firmware or IGBT module replacement may take 10-14 days. We offer expedited 48-hour repair for critical spares. Synchronics provides loaner equipment during repair for zero downtime in production plants.
Why do STOBER gearboxes fail prematurely in Indian textile mills?+
STOBER helical and bevel gearboxes in Indian textile mills fail early due to: (1) prolonged operating temperatures above 45°C without adequate ventilation, causing oil degradation; (2) infrequent oil changes leading to metal particle buildup and bearing wear; (3) dust and moisture ingress from open mill floors. Synchronics recommends ISO 220 synthetic oil, quarterly filter changes, and sealed bearing housings for Indian climates. We service 100+ STOBER units annually in Gujarat and Maharashtra textile regions.
Can STOBER servo drives be repaired if they show fault code E15 or E22?+
Yes. E15 typically indicates encoder signal loss or quadrature error; E22 signals thermal overload. Synchronics diagnoses the root cause (misaligned encoder, fouled heatsink, or failed thermistor) and restores the drive without replacing expensive modules. We stock genuine STOBER encoder sensors and replacement thermistors. Most E15/E22 faults are resolved within 3-4 days at 60% less than new drive cost.
Are STOBER electromagnetic brake repairs cost-effective vs. replacement?+
For Indian users, STOBER brake repair is highly cost-effective. A replacement electromagnetic brake motor (STOBER EB or SB series) costs INR 40,000-80,000; coil replacement via Synchronics costs INR 8,000-12,000. Synchronics has repaired 500+ STOBER brakes for cranes, hoists, and vertical conveyors across India. Repaired units meet original performance spec and carry 12-month warranty.
How do I send my STOBER 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. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.
What is the cost of repairing a STOBER 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 STOBER 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 STOBER 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.
