GENERAL RESISTANCE Product Lines We Repair
Our engineers are trained on the full GENERAL RESISTANCE product range. Below are the major product families we service.
Wire-Wound Power Resistors
Heavy-duty wire-wound resistor assemblies for motor soft-starters, variable frequency drive dynamic braking, and AC line reactors. Common failures include open windings, element fracture under thermal cycling, and solder joint degradation in Indian high-temperature industrial environments.
Dynamic Braking Resistor Banks
Segmented resistor banks used in VFD deceleration circuits and regenerative motor systems. Typical faults include unbalanced load distribution across segments, element burnout during emergency stop cycles, and insulation breakdown under moisture ingress in humid manufacturing plants.
Rheostat / Starter Resistors
Variable resistor control elements for wound-rotor induction motors, crane hoist systems, and legacy AC motor soft-start circuits. Common repair issues: sliding contact wear, carbon film degradation, and temperature coefficient drift affecting motor acceleration profiles.
Load Bank Resistor Elements
Distributed resistor matrices for generator testing, UPS load simulation, and power supply commissioning. Failure modes include uneven thermal distribution, element shorting due to moisture, and mechanical loosening of terminal connections under vibration.
Film / Metal Oxide Resistors
Precision thin-film resistors for signal conditioning, surge protection, and measurement circuits in industrial control panels. Typical failures: tolerance drift under thermal stress, bond-wire fracture in power dissipation events, and moisture ingress through epoxy coating.

Common GENERAL RESISTANCE Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in GENERAL RESISTANCE equipment arriving at our workshop.
- ✓Open-Circuit Winding in Power Resistor — Cyclic thermal stress and vibration cause fatigue fracture in wire-wound elements. Indian high-ambient temperature plants (40-50°C) accelerate oxidation and brittleness in uncoated nichrome wire.
- ✓Dynamic Braking Resistor Burnout — Excessive regenerative current during emergency stop or oversized inertial loads. Unbalanced segment distribution causes hot-spots; inadequate airflow in dusty mills worsens heat dissipation.
- ✓Rheostat Sliding Contact Noise and Intermittency — Mechanical wear of carbon brush against resistor element surface; carbon dust accumulation; corrosion from humidity and salt-fog in coastal Indian plants.
- ✓Moisture Ingress and Insulation Failure — Epoxy coating micro-cracks due to thermal cycling; compromised seals in resistor housing; condensation in humid monsoon seasons affecting load bank installations in uncontrolled warehouses.
- ✓Load Bank Segment Resistance Mismatch — Unequal thermal aging across multi-element banks; manufacturing tolerance stack-up; solder joint high-resistance connections causing localized heating.
- ✓Starter Rheostat Temperature Coefficient Drift — Nichrome wire resistance changes with temperature; coil winding density varies across turns causing non-linear acceleration. Dust and oxidation layer buildup alters effective resistance value.

Frequently Asked Questions — GENERAL RESISTANCE Repairs
Do you repair General Resistance resistors across India?+
Yes. Synchronics repairs the entire General Resistance product portfolio — wire-wound power resistors, dynamic braking banks, rheostats, load banks, and precision film resistors. We offer PAN India door-to-door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, Kolkata, and all industrial hubs. Repair work is completed at our 18000 sqft Vadodara facility with same-day testing turnaround for most resistor failures.
What tests does Synchronics perform on repaired General Resistance resistors?+
After repair, we conduct: cold resistance measurement at 25°C (comparison to General Resistance spec sheets), continuity and megohm insulation testing, full-load thermal imaging and IR analysis, vibration endurance testing for power resistors, sliding contact sweep testing for rheostats, and dynamic braking circuit simulation for load bank resistors. All test data is documented and certified.
Why do General Resistance power resistors fail in Indian steel mills and cement plants?+
Indian hot-climate manufacturing (ambient 45-50°C) stresses nichrome wire windings. High dust concentration in steel mills clogs cooling fins, trapping heat. Monsoon humidity causes epoxy micro-cracks and moisture ingress. Overloaded soft-starters on aged motors demand excessive braking current. Synchronics addresses root causes by upgrading cooling, recoating, and verifying soft-starter settings to prevent repeat failures.
Can you repair or re-wind General Resistance braking resistor banks for larger VFD systems?+
Yes. We rebuild General Resistance dynamic braking resistor banks up to 1000kW+ by recalculating segment load distribution, replacing burned elements with matched resistance values, and rebalancing parallel paths. Our engineers work with VFD parameters to ensure braking curve stability. Rebuilt banks undergo full power test before shipment.
How quickly can Synchronics repair a failed General Resistance rheostat in a live production plant?+
For critical motor starters and crane controls, Synchronics offers emergency same-day repair in Vadodara (4-6 hours turnaround) or emergency parts loan while your rheostat is rewound. We also provide on-site troubleshooting in Mumbai, Delhi, Pune, and Hyderabad to minimize downtime on customer lines.
How do I send my GENERAL RESISTANCE 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 GENERAL RESISTANCE 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 GENERAL RESISTANCE 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 GENERAL RESISTANCE 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.
