IM Product Lines We Repair
Our engineers are trained on the full IM product range. Below are the major product families we service.
IM Classic AC Motors (IE1/IE2/IE3)
Standard three-phase squirrel-cage motors ranging from 0.5 kW to 315 kW, widely used in Indian textile, cement, and chemical plants. Common faults include winding insulation breakdown, bearing seizure, and rotor bar fractures.
IM IE4 Premium Efficiency Motors
Ultra-efficient permanent magnet-assisted synchronous motors (IE4 certified) for energy-critical applications. Prone to magnet demagnetization under thermal stress and stator winding partial discharge issues in contaminated environments.
IM Compact Geared Motors
Integrated helical and bevel gear units coupled to IM motors for torque multiplication in conveyor drives and mixer applications. Repair challenges include gear tooth spalling, seal leakage, and motor-to-gearbox misalignment issues.
IM Servo and Position Control Motors
Low-inertia servo motors with integrated encoders and feedback systems for precision textile looms and packing machinery. Common faults include encoder signal loss, servo controller board capacitor failure, and commutation phase misalignment.
IM Wound-Rotor (Slip-Ring) Motors
Three-phase motors with external rotor resistance for soft-starting in high-inertia load applications like mill crushers and large compressors. Repair involves slip-ring brush replacement, rotor resistance grid restoration, and control circuit diagnostics.
IM Explosion-Proof Motors (ATEX)
Certified Ex d and Ex e motors for hazardous area use in pharmaceutical, chemical, and petrochemical facilities across India. Repairs require strict ATEX compliance, including flange certification and pressure-relief valve recalibration.

Common IM Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in IM equipment arriving at our workshop.
- ✓Stator winding insulation breakdown under moisture — IM motors in humid Indian textile mills and coastal plants often experience winding-to-frame insulation failure due to condensation ingress and inadequate drainage in motor feet. Operating temperature rise accelerates degradation of polyimide-class insulation systems.
- ✓Rotor bar fracture and end-ring cracking — High starting torque demands, frequent soft-start failures, and vibration from unbalanced loads cause aluminum rotor bars in IM IE3 motors to fatigue and crack. Indian cement mills and sugar industries experience this under heavy load cycling.
- ✓Bearing preload loss and inner-race spalling — IM motors running continuously in high-ambient environments (50°C+) experience accelerated bearing grease oxidation and loss of preload, leading to axial play and race damage. Common in Indian foundries, steel mills, and textile dyeing units.
- ✓Servo motor encoder signal loss and jitter — Dust ingress into encoder housings on IM Servo-Compact motors in textile looms causes optical sensor contamination and intermittent signal dropout. Vibration and thermal cycling degrade connector contacts in control cables.
- ✓IE4 permanent magnet demagnetization and cogging torque increase — IM Neosynchro motors exposed to sustained overload or thermal transients above 100°C experience partial NdFeB magnet demagnetization, reducing torque output and increasing cogging ripple. Occurs in energy-critical applications with inadequate thermal management.
- ✓Gearbox seal leakage and oil contamination in coupled motors — IM Compact Geared Motor seals degrade due to pressure surges from cavitation, thermal cycling, and inadequate oil change intervals in Indian sugar and chemical plants. Contaminated oil accelerates bearing wear.

Frequently Asked Questions — IM Repairs
Do you repair IM equipment anywhere in India?+
Yes. Synchronics repairs the full IM motor and drive system portfolio across India. We provide PAN-India door pickup and delivery from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Kolkata, and all major industrial cities. All repairs are completed at our ISO 9001-certified facility in Vadodara, Gujarat, with same-day or next-day collection by our logistics partners.
Can Synchronics repair IM IE4 motors, and do you verify efficiency after rewinding?+
Yes, we specialize in IM IE4 (Neosynchro series) motor repair. After rewinding, we perform full no-load and full-load testing on our 400 kVA test bed, measuring efficiency against IEC 60034-2-1 standards. We supply efficiency test certificates and guarantee IE3 minimum efficiency after repair. Magnet field strength is verified with gauss mapping, and thermal imaging confirms uniform cooling.
What is your turnaround time for IM geared motor repair?+
Standard IM geared motor repairs (seal replacement, bearing change, oil service) take 5-7 working days. Full motor rewind with gearbox overhaul takes 12-15 days. Emergency expedited repairs are available (3-5 days) for critical production equipment. We provide free loan units for textile and sugar mills during repair periods upon request.
Do you handle IM ATEX explosion-proof motors, and are repairs certified?+
Yes. Synchronics is authorized to repair IM ATEX Ex d and Ex e motors. All repairs comply with ATEX Directive 2014/34/EU and Indian PESO (Petroleum and Explosives Safety Organization) certification requirements. We recalibrate pressure-relief valves, verify flange integrity with pressure testing, and issue full ATEX compliance documentation with each repair.
What warranty do you provide on IM motor and geared motor repairs?+
All IM motor repairs come with a 12-month warranty on rewound windings, bearings, and seals against manufacturing defects. Extended 24-month warranties are available for critical mill equipment. We include free thermal imaging inspection at 3-month and 12-month service intervals post-repair to ensure long-term reliability.
How do I send my IM 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 IM 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 IM 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 IM 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.
