UNIMOTOR Equipment We Repair — By Category
UNIMOTOR Product Lines We Repair
Our engineers are trained on the full UNIMOTOR product range. Below are the major product families we service.
UNIMOTOR AC Motor Series
Three-phase and single-phase AC induction motors (0.5 kW to 15 kW) commonly used in packaging machinery, textile spindles, and conveyor systems. Prone to winding insulation breakdown, bearing wear, and capacitor failure in humid Indian factory environments.
UNIMOTOR DC Motor Range
Brushed and brushless DC motors (1-5 kW) for precision positioning in printing presses, winding equipment, and CNC auxiliary drives. Common faults include brush wear, commutator pitting, and armature coil insulation damage from thermal cycling.
UNIMOTOR Servo Drive Module
Integrated servo motor controllers with embedded feedback systems for synchronous drives in multi-spindle machines. Vulnerable to capacitor aging, gate driver faults, and encoder signal loss in industrial environments.
UNIMOTOR Brake Motor Units
Friction and electromagnetic brake-equipped motors for safety-critical applications in hoists, lifts, and material handling. Spring mechanical brake failures and solenoid coil burnout are frequent repair issues in Indian plants.
UNIMOTOR Geared Motor Systems
Compact helical gearbox motors (0.25-2 kW) for pharmaceutical and FMCG packaging lines. Gearbox oil seal leakage, gear tooth wear, and motor shaft coupling looseness are typical failure modes.

Common UNIMOTOR Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in UNIMOTOR equipment arriving at our workshop.
- ✓Winding insulation breakdown in AC motors — UNIMOTOR AC motors operating in high-humidity textile mills and food factories experience accelerated insulation degradation. Moisture ingress, thermal cycling, and contamination from dust and chemical vapors compromise winding dielectric strength, leading to phase-to-phase or phase-to-ground short circuits.
- ✓Bearing seizing and noise in DC servo motors — UNIMOTOR servo drives with sealed bearings suffer lubrication breakdown under continuous-duty conditions. Inadequate regreasing intervals combined with vibration and thermal expansion cause race spalling and internal grinding noise within months of operation.
- ✓Capacitor failure in brake solenoid circuits — Electrolytic capacitors in UNIMOTOR brake motor solenoid control stages degrade rapidly in Indian foundries and steel plants where ambient temperatures exceed 45-50 degrees Celsius. Voltage spikes from switching transients accelerate capacitor aging and lead to open-circuit brake failure.
- ✓Encoder signal loss in servo drive modules — UNIMOTOR servo motors with integrated encoders lose absolute position feedback when encoder ribbon cables become crimped, corroded, or poorly seated in multi-spindle applications with frequent vibration. This triggers servo fault codes and halts synchronized production.
- ✓Gearbox oil seal leakage and contamination — UNIMOTOR geared motor units in pharma packaging lines develop oil seepage at motor-gearbox interface due to thermal expansion mismatch and seal lip wear. Leaked oil attracts dust and contaminates motor bearings, accelerating bearing failure.
- ✓Commutator pitting and brush arcing in DC motors — High-current transients and inadequate brush maintenance in UNIMOTOR DC motors used in winding and unwinding drives create arcing at commutator segments. Carbon brush particles accumulate and cause intermittent contact resistance, leading to torque ripple and electrical noise.

Frequently Asked Questions — UNIMOTOR Repairs
Do you repair UNIMOTOR equipment anywhere in India?+
Yes. Synchronics repairs the full UNIMOTOR product range — AC motors, DC motors, servo drives, brake motors, and geared units. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Surat, Nagpur, and all other cities. Fast-track service from our main facility in Vadodara, Gujarat.
What is the typical turnaround time for UNIMOTOR motor rewinding in India?+
For standard UNIMOTOR AC and DC motor rewinding, Synchronics delivers 5-7 working days in Vadodara and Gujarat region. PAN India shipment adds 2-3 business days. For critical production lines, we offer 48-hour express rewinding with overnight courier delivery. Brake motor and servo drive repairs require 7-10 days due to board-level diagnostics and thermal testing.
Can Synchronics repair UNIMOTOR servo drives with fault codes?+
Yes. Synchronics decodes UNIMOTOR servo drive fault codes (encoder loss, overcurrent, temperature faults) through board-level testing with oscilloscope and logic analyzer. We repair power stage failures, replace defective gate drivers, reseat encoder connectors, and validate against factory test specifications before dispatch. Most servo drives return within 10 days.
Do you stock UNIMOTOR replacement parts and bearings?+
Synchronics maintains stock of critical UNIMOTOR spares including sealed bearings (6203, 6205, 6305 series), carbon brushes, oil seals, and capacitors. For motor-specific windings and gearbox internals, we procure direct from authorized UNIMOTOR distributors with 3-4 day lead time. We never compromise on OEM-equivalent quality for Indian industrial customers.
What warranty do you offer on UNIMOTOR motor repairs?+
Synchronics guarantees 18 months on all UNIMOTOR motor rewinding and 12 months on servo drive repairs from date of dispatch. Warranty covers winding failure, bearing seizing, and component defects under normal industrial operating conditions. On-site warranty support available across India for plants in automotive, textile, and pharma sectors.
How do I send my UNIMOTOR 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 UNIMOTOR 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 UNIMOTOR 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 UNIMOTOR 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.
