// WHAT WE DO
Comprehensive repair of electric machines and generators of any complexity
Elektropromremont repairs, modernizes and services industrial electric machines. We work with induction and synchronous motors, DC machines, generators and special-purpose electric machines of various designs.
We carry out diagnostics and fault detection, electric motor rewinding — including stator and rotor rewinding — armature repair, manufacture of windings and spare parts, restoration of mechanical assemblies, balancing, assembly and testing of equipment.
Large electric machines can be repaired and serviced directly where the equipment is installed.
// GENERATOR OVERHAUL// EQUIPMENT NOMENCLATURE
Electric machines we repair
We repair and modernize industrial electric machines of various types, designs and ratings — from series-produced motors to large and special-purpose machines.
Choose a type of electric machine to learn more about our repair technologies and production 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 machines
Comprehensive repair of synchronous machines, turbo and hydro generators with full restoration of the electrical and mechanical parts.
Repair of DC machines
Repair of DC machines for metallurgy, mining, transport, and heavy engineering.
Repair of 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.
Diagnostics and testing
A full complex of electrical, mechanical, and thermal imaging tests before, during, and after repair.
Field work
We repair electric machines directly at the Customer's site using mobile equipment and our own service teams.
Mechanical and service work
Machining and restoration of parts, balancing, alignment and manufacture of parts to drawings or samples — at our own works and at the Customer’s site.
// COMPLETE APPROACH
The whole repair cycle at one company
Electrical production, machining, diagnostics, testing and on-site service are combined into a single process.
This lets us carry out a complete repair of an electric machine at one production facility — from assessing the equipment’s condition to its acceptance tests and return to service.
- 01Diagnostics
- 02Fault detection
- 03Electrical repair
- 04Mechanical restoration
- 05Balancing
- 06Assembly
- 07Testing
- 08Installation and start-up
The scope and order of work are set individually after fault detection and depend on the design and condition of the electric machine.
// HOW WE WORK
From a single part to a complete repair
// A SINGLE OPERATION
The Customer can hand us a single shaft, rotor, armature, stator, bearing assembly or other part for one specific operation.
// A COMPLETE REPAIR
Or entrust us with a complete repair of the electric machine — from fault detection and manufacture of the components it needs to assembly, testing, installation and start-up.
For non-standard and large equipment, we decide the repair method case by case after reviewing technical documentation, drawings or photographs, or inspecting the machine.
// REPAIR COST
Cost of electric motor repair
There is no fixed price list for electric motor repair, because the cost of repairing and rewinding a motor is calculated individually once its condition and the scope of work have been established.
The price depends on the type, rating and design of the electric machine, the nature of the damage, how much rewinding is needed, whether mechanical restoration or manufacture or replacement of parts is required, the materials and the set of tests.
For a preliminary estimate, send us a photo of the nameplate, photos of the equipment and a short description of the fault. For complex and large machines, the final scope of work is set after fault detection.
No full technical specification?
Send photos of the equipment and its nameplate — we will help you work out what data is needed for a preliminary estimate.
