HEVI-DUTY ELECTRIC Product Lines We Repair
Our engineers are trained on the full HEVI-DUTY ELECTRIC product range. Below are the major product families we service.
Hevi-Duty DC Motors
Wound-field and permanent magnet DC motors designed for high-torque variable-speed applications. Common issues include commutator wear, brush deterioration, field coil insulation breakdown, and armature short circuits affecting speed regulation.
Hevi-Duty AC Induction Motors
Three-phase squirrel-cage and wound-rotor motors for continuous industrial duty. Repair challenges include bearing seizure, stator winding phase-to-ground faults, rotor bar fractures, and thermal overload in high-ambient environments.
Hevi-Duty Soft Starters and Controllers
Electronic soft-start units and motor control terminals for reduced inrush current and smooth acceleration. Common faults include thyristor failures, current-sensing module drift, timing circuit instability, and communication loss in networked controllers.
Hevi-Duty Wound-Rotor Motor Systems
Slip-ring induction motors with external rotor resistance for applications demanding precise speed and torque control. Typical failures involve slip-ring brush wear, rotor winding insulation faults, and resistance element degradation.
Hevi-Duty Geared Motor Assemblies
Integrated motor and gearbox units for mining, cement, and material-handling operations. Repair issues include motor bearing wear, coupling misalignment, gear oil contamination, and motor-to-gearbox mounting stress fractures.

Common HEVI-DUTY ELECTRIC Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in HEVI-DUTY ELECTRIC equipment arriving at our workshop.
- ✓Commutator blackening and brush chatter in DC motors — Hevi-Duty DC motor commutators oxidize and develop high-resistance surface films when exposed to humid or corrosive plant environments common in Indian coastal and chemical manufacturing zones. Undersized or worn brushes lose contact pressure, causing arcing.
- ✓Stator phase-to-ground shorts in AC motors — Hevi-Duty AC motor stators fail insulation between phase windings and steel core due to thermal aging, moisture ingress, or bearing-related mechanical vibration damage. Phase-to-ground faults cause immediate thermal trips and motor shutdown.
- ✓Bearing wear and radial play noise — Hevi-Duty motors running on Indian plant floors with poor alignment, inadequate lubrication schedules, or contaminated bearing grease develop radial play exceeding 0.5 mm. This causes mechanical noise and eventual bearing cage collapse.
- ✓Soft starter thyristor open-circuit or gate-drive failure — Hevi-Duty soft starters in dusty steel mills and cement plants experience thyristor failures when gate-drive circuits lose signal due to cold-solder joints, capacitor degradation, or photocoupler isolation breakdown in the trigger module.
- ✓Slip-ring brush chatter and arcing on wound-rotor motors — Hevi-Duty wound-rotor motors with external slip-rings and brushes suffer deterioration when rotor frequency drops below nameplate during soft-starting transients. Mismatched brush materials and contaminated slip-ring surfaces cause intermittent contact.
- ✓Gearbox coupling wear and motor vibration issues — Hevi-Duty geared motor assemblies in mine hoists and cement kilns develop coupling backlash and radial misalignment when foundation bolts loosen and flexspline teeth wear. Unbalanced radial loads exceed motor bearing ratings.

Frequently Asked Questions — HEVI-DUTY ELECTRIC Repairs
Do you repair Hevi-Duty Electric equipment anywhere in India?+
Yes. Synchronics repairs the full Hevi-Duty Electric product range — DC motors, AC induction motors, soft starters, wound-rotor assemblies, and geared motor units. We offer pan-India door pickup from Mumbai, Delhi, Pune, Ahmedabad, Chennai, Hyderabad, Bangalore, and all other industrial cities. All repairs are handled at our 30-year-old Vadodara, Gujarat facility with 180+ engineers specialized in motor and drive systems.
What is the typical repair turnaround time for a Hevi-Duty DC motor rewind?+
A complete Hevi-Duty DC motor armature rewind and commutator resurfacing typically takes 5-7 working days from receipt, depending on motor frame size and damage extent. If commutator turning and brush replacement are needed, we can often complete smaller motors (under 50 HP) in 3-4 days. Synchronics prioritizes emergency restarts — call our hotline for same-day diagnostics and expedited scheduling.
Do you stock spare brushes and commutators for Hevi-Duty motors?+
We maintain in-stock brushes, brush springs, and commutator rebuild kits for most common Hevi-Duty motor frames. For rare or custom-wound-rotor machines, we source original Hevi-Duty components through authorized distributors within 48-72 hours. We also provide alternative OEM-equivalent grade brush materials rated for Indian industrial duty cycles and high-ambient environments.
Can Synchronics diagnose a Hevi-Duty soft starter that trips on inrush current?+
Yes. Synchronics troubleshoots Hevi-Duty soft starters by measuring gate-drive voltages, analyzing thyristor forward-drop curves, checking current-sense feedback calibration, and verifying ramp-time settings. Common causes in Indian plants include dusty environments affecting photocoupler isolation, solder-joint cold-cracks in the trigger PCB, and capacitor dry-out in high-temperature switchgear rooms. We recalibrate or replace the entire soft-start module and perform field acceptance testing.
Why is my Hevi-Duty wound-rotor motor losing speed under full load?+
Hevi-Duty wound-rotor motors lose speed when external rotor resistance grids develop open or burnt resistor elements, or when slip-ring brush connections become intermittent. This reduces rotor-side resistance and allows slip to increase. Synchronics measures resistance grid continuity using megger and ohm-meter tests, replaces burnt resistor elements, and cleans slip-ring surfaces. We also verify that field voltage to the stator remains at nameplate rating (critical for older Hevi-Duty designs with external field rheostats).
How do I send my HEVI-DUTY ELECTRIC 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 HEVI-DUTY ELECTRIC 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 HEVI-DUTY ELECTRIC 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 HEVI-DUTY ELECTRIC 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.
