WUXI TONGHUI MOTORS CO LTD Repair Services India

Yes. Synchronics repairs the complete Wuxi Tonghui Motors range - three-phase induction motors, high-slip crane motors, IE3 premium efficiency designs, and VFD-compatible variants. We offer PAN-India door pickup from Mumbai, Pune, Ahmedabad, Delhi, Bangalore, Chennai, Hyderabad, Jaipur, and all industrial hubs. All repairs are centralised at our Vadodara, Gujarat facility where 180+ engineers execute motor rewinding, bearing replacement, VFD compatibility upgrades, and performance testing.

Synchronics typically repairs Wuxi Tonghui three-phase motors within 5-7 working days including rewinding, testing, and dispatch. Large motors (>110 kW) and high-slip rotor rewinds may require 10-14 days. All repairs come with a comprehensive 12-month warranty covering materials, workmanship, and rewind insulation (Class F minimum, Class H available). We provide pre-repair quotes, damage assessment reports, and post-repair insulation resistance certificates (megohm testing at 500V DC minimum).

Standard Wuxi Tonghui IE2 motors operate safely with PWM VFDs but are not optimised for dV/dt stress. IE3 and VFD-ready variants show better compatibility but still risk partial discharge at switching frequencies >8 kHz. Synchronics upgrades Tonghui motors for VFD duty by reinforcing stator insulation, adding dV/dt phase filters, and grounding neutral points. We test compatibility with customer VFD brands (Danfoss, Schneider, ABB, Yaskawa, Siemens) before handover and provide surge suppression recommendations.

Yes. Synchronics specialises in high-slip rotor motor rewinds for Tonghui wound-rotor designs. Our engineers replace fractured rotor coils, repair rotor ring braze joints, upgrade slip-ring brush systems, and balance rotors to ISO 1940 G2.5 grade. Textile mill applications (spinning frame duty) and crane/hoist loads receive stress-relieved copper windings and thermal cycling validation. We maintain rotor slip characteristics within 3-5% of original OEM design.

Wuxi Tonghui motor repair typically costs 40-60% of new motor price, depending on damage severity and winding complexity. For textiles, pumps, and crane applications in small-to-medium Indian facilities, repair ROI is positive within 6-18 months of operational service. Synchronics offers transparent repair quotes, non-destructive diagnostics (thermography, surge impedance, vibration analysis), and upgraded insulation systems that extend motor life beyond original OEM durability. Supply chain delays for new imported motors often justify immediate repair decisions.

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.

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.

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.

Yes. If we cannot repair your WUXI TONGHUI MOTORS CO LTD 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.
