Industrial Motor Rewinding & Professional Coil Repair Services
In industrial facilities, a winding failure in electric motors—the heart of your operations—can bring your entire production line to a standstill. Our motor rewinding and coil repair service is more than just replacing burnt wires; it is a meticulous engineering process designed to restore a motor’s electrical and mechanical specifications to original factory values—or even exceed them. Operating from our specialized workshop in Kahramankazan, Ankara, we utilize high-grade F and H-class heat-resistant materials to significantly extend the operational life of your motors.
Professional Rewinding Process & Advanced Insulation Technology
Unlike standard rewinding shops, we target the long-term durability of the motor under grueling conditions such as extreme overloading and high ambient temperatures. Our engineering-supervised procedures include:
- Precision Stripping & Cleaning: Burnt windings are removed using thermal stripping methods that protect the integrity of the stator laminations, followed by 100% thorough slot insulation cleaning.
- Premium Material Usage: We utilize H-Class (200°C) enameled copper wires and Nomex insulation papers. This superior material selection minimizes the risk of future burnouts even during heavy industrial stress.
- Vacuum Pressure Impregnation (VPI) & Baking: Once wound, the motor is placed in a vacuum tank to ensure the varnish penetrates the deepest points of the coils, followed by controlled oven-baking. This prevents winding vibration (humming) and mechanical wear.
- Testing & Performance Reporting: Every motor is tested under both idle and load conditions within a crane control panel simulation. We provide detailed reports on amperage balance and insulation resistance.
Motor Types & Brands We Service
Our workshop provides comprehensive rewinding services for a vast range of industrial motors, from 0.18 kW to high-capacity heavy-duty units:
- Crane Motors: Specialized rewinding for conical rotor, braked, and dual-speed hoist motors, including precise brake calibration procedures.
- Induction Electric Motors: Three-phase and single-phase motors from leading brands such as Gamak, Volt, Wat, Siemens, and ABB.
- Specialized Units: High-precision servo motors, DC motors, submersible pumps, and industrial vibration motors.
- Total Mechanical Overhaul: During the rewinding process, motor end shields, bearing seats, and shafts are inspected. Any necessary mechanical repairs are handled in-house by our master technicians.
Why Choose Rewinding Over Replacement?
A correctly executed motor rewinding process restores your equipment to factory condition while providing significant B2B advantages:
- Substantial Cost Savings: Compared to the capital expenditure of a new European-manufactured motor (Demag, Kone, ABM, etc.), professional rewinding is typically 60-70% more economical.
- Speed & Operational Continuity: While the procurement of specialized industrial motors can take weeks, our rewinding process is completed in 1-2 business days, preventing massive production losses.
- Enhanced Durability: Through the use of high-class insulation materials, we can upgrade your motor to have higher heat resistance than its original factory state.
Frequently Asked Questions (FAQ)
1. Does a rewound motor lose performance?
No. In fact, if high-quality copper and advanced varnishing technologies (such as H-class insulation) are used, the motor’s durability increases. Rewinding performed with precise engineering calculations preserves 100% of the original torque and RPM values.
2. How long does the rewinding process take?
Depending on the kW rating and damage level, standard induction motors are typically completed within 1 business day. Specialized crane motors, including testing phases, are delivered within 1-2 business days.
3. Do you provide a warranty for the service?
Yes. As Vinç Kumanda Servisi, all motors rewound in our facility are covered by a comprehensive warranty against electrical workmanship and material defects. Mechanical procedures, such as bearing replacements, are also under our guarantee.
4. Can you identify why my motor burned out?
Absolutely. During disassembly, our master technicians analyze the burn patterns to identify root causes such as phase loss, overloading, or rotor jamming. We report these findings to you so you can implement the necessary system improvements to prevent recurrence.
