We build a solid foundation for your business

If any electric motor, dynamo, air or oil transformer fails, our well-coordinated team of employees is at your disposal, who can eliminate even very complicated faults.

• Revisions and complete repairs of el. rotating machines (repairs of electric motors)
⦁ synchronous and asynchronous motors up to voltage 11 kV and power 10 MW
⦁ DC motors and dynamos up to 1 kV and 3 MW
⦁ special motors (traction, for non-explosive environment)
• Revision, complete repairs and rewinding of transformers
⦁ dry and oil transformers up to voltage 35 kV and output 6300 kVA
⦁ special transformers and chokes (furnace, traction, etc.)
⦁ oil check, filtration, or replacement during repairs (some operations can be performed directly at the customer)
⦁ liquidation and purchase of discarded and unused transformers – dry and oil
⦁ The control of repaired transformers is supplemented by a control measurement with an infrared camera
• Inspections and repairs of special machines
⦁ repairs of water and sludge pumps
⦁ repairs of electric welders, repairs of electric power plants up to 1 MW
⦁ eldra up to 3 kW (electrohydraulic brake release ELHY)
⦁ load magnet special coil
• Special work, service activities
⦁ balancing of rotating bodies
SCH SCHENK balancing machine – type H50V – works with bodies with a maximum length of 4 m, a diameter of 1.8 m and a       weight of 4 t
⦁ part of the balancing is the transmission of a report on the course and overall balance of the balanced body
⦁ vibrodiagnostics – analysis of balance and quality of bearings
• Thermal imaging measurements

• Laser positioning of electric machines

⦁ electrotechnical measurements
⦁ metallurgical measurements
⦁ construction issues
⦁ other measurements

Electric motors

Asynchronous motors
Powers: 1 kW to 7 MW
Voltage: low voltage up to 1,000 V; HV up to 11,000 V
Speed: up to 3,600 rpm
Design: horizontal, vertical, non-explosive

Scope of work
The inspection usually involves ecological cleaning of the machine, drying of the machine and restoration of the insulation resistance of the machine winding, repair and renewal of impregnating and electrical insulating coatings, inspection of stator windings, replacement of bearings, inspection of mechanical operation of machine, inspection of terminal block, inspection of thermometers in machine. We perform new surface coatings of the machine, control electrical measurements of the machine.
Machine repair usually involves ecological cleaning of the machine, drying of the machine and restoration of insulation resistance of the machine winding, repair and restoration of impregnating and electrical insulating coatings, inspection of stator winding, bearing replacement, dynamic rotor balancing, repair of damaged mechanical machine parts, machine mechanical operation, repair and inspection outlet terminal block, replacement of thermometers in the machine. We perform new surface coatings of the machine, control electrical measurements of the machine.

Machine overhaul usually involves ecological cleaning of the machine, complete rewinding of the machine with new coils, new impregnation of the machine winding, preparation of electrical insulating coatings, repair of free rotor end, repair of pins and bearing replacement, dynamic rotor balancing, machine mechanical operation control, terminal block replacement, thermometer replacement in the machine. In the event of a machine accident, we will check and repair the magnetic circuit of the machine. We will perform new surface coatings of the machine and all electrical measurements of the machine. For machines after overhaul, we offer service monitoring in further operation in the form of preventive prophylactic measurements. The aim is to ensure trouble-free operation and early warning in the event of deteriorating machine condition.
