// WHAT WE DO
Comprehensive repair of electric machines and generators of any complexity
We perform overhaul, medium, and routine repair of asynchronous and synchronous electric motors, DC machines, turbo generators, hydro generators, and traction electric machines. The company provides a full production cycle — from technical diagnostics and fault detection to manufacturing components, stator rewinding, rotor rewinding, assembly, balancing, high-voltage testing, and equipment commissioning.
Repair includes restoration or manufacture of stator and rotor windings, stator rewinding, rotor rewinding, repair of shafts, bearing assemblies, housing components, cooling systems, commutators, slip rings, squirrel-cage rotors, and other components of the electric machine. If necessary, we also perform design modernization, manufacture spare parts, and restore technical documentation.
// GENERATOR OVERHAULEvery repaired electric machine undergoes balancing, a complex of electrical and mechanical tests, and quality control at our own test station. The Customer receives equipment fully ready for safe and reliable operation.
// EQUIPMENT NOMENCLATURE
Electric machines we repair
We perform repair, modernization, and service maintenance of AC and DC electric machines. Each area has its own repair technologies, specialized equipment, and dedicated specialists. Choose an equipment category to learn more about our capabilities.
Repair of asynchronous electric motors
Repair and rewinding of asynchronous AC electric motors of any complexity — from general industrial machines to high-voltage, high-power motors.
Repair of synchronous electric motors and generators
Comprehensive repair of synchronous machines, turbo and hydro generators with full restoration of the electrical and mechanical parts.
Repair of DC motors
Repair of DC machines for metallurgy, mining, transport, and heavy engineering.
Repair of electric motors with loose winding
Repair of low- and medium-power electric motors with round-wire (loose) winding for industrial equipment.
Manufacturing of spare parts
In-house manufacturing of components for electric machines from drawings or samples, with a full production cycle.
Field work
We repair electric machines directly at the Customer's site using mobile equipment and our own service teams.
Test station and diagnostics
A full complex of electrical, mechanical, and thermal imaging tests before, during, and after repair.

// OTHER SERVICES
Machining, balancing and diagnostics
Individual services the company performs both as part of a repair and as a standalone service for the customer.
Worn and damaged parts and assemblies of electric machines are repaired by surfacing, followed by turning, milling, drilling and other machining. We inspect, restore and manufacture:
Elevated vibration wears down a machine's core components over time, and imbalance of rotating mechanisms is behind most of it. We perform static and dynamic balancing of rotors, armatures, fans and impellers on our balancing machine and in their own bearings, both on-site and at the customer's facility.
Under the measurement scope attached to our Certificate of Technical Competence, the test station measures and tests electrical equipment across four parameter groups.
// ROTATING MACHINES
// GROUNDING DEVICES
// INSTALLATIONS UP TO 1000V
// POWER CABLE LINES
Skilled use of measurement, testing and vibration-analysis results lets our specialists accurately diagnose an electric machine and prevent premature failure.
