Repair, Rewind & Refurbishment
Comprehensive repair, rewinding, and refurbishment of industrial rotating electrical machines—from low-voltage motors to high-voltage generators up to 700 MW and 22 kV, including power transformers—restoring equipment to OEM or better performance.
Machines We Handle
Motors
AC induction (Squirrel-cage & Slip-ring) • Synchronous (Salient-pole & Cylindrical) • DC motors • High power-density Permanent Magnet motors
Generators
Air, Hydrogen, and Water-cooled generators
Transformers
Power, Isolation, and Utility transformers — Dry-type or Oil-immersed
Coils
Reactor coils and Magnetic coils
Capabilities
RKELC delivers in-situ and workshop-based repair, rewinding, and overhaul services for steam, gas, and hydro generators, AC/DC motors, and other static electrical assets. Supported by ISO-certified facilities, advanced automatic and semi-automatic coil manufacturing and testing equipment, and a highly trained workforce, we ensure consistent, high-quality outcomes for high-voltage and mission-critical machines.
Electrical
- Rewinding of hydrogen- and water-cooled turbine generators with Roebel coil technology
- Motor and generator rewinding with Resin-Rich or VPI insulation systems
- Cylindrical and salient-pole rotor rewinding with coil replacement or re-insulation
- Power, voltage, and frequency conversion upgrades for generators and motors
Mechanical
- Core restacking and lamination replacement
- Rotor component repair/replacement (shafts, end-shields, cooling fans) to OEM specifications
- Bearing journal and babbitted bearing rebuilt to OEM tolerances
- On-site jig/optical/laser/wire machining
- Rotor dynamic balancing up to 22 tons (high-speed on application basis)
Preventive Maintenance & Overhauling
Motors & Generators
- Dry-ice cleaning to remove oil, dust, and contaminants from windings without thermal impact
- Varnishing and insulation rejuvenation for extended life and reliability
- Alignment, balancing, and mechanical adjustments to OEM tolerances
Power Transformers
- Complete overhaul, gasket replacement, and OEM component upgrades
- Ultra-High-Vacuum (UHV) transformer oil filtration to restore dielectric performance
- On-site or in-facility servicing to reduce downtime and outage windows
