REPAIR OF ELECTRIC MOTORS
We maintain all types of electric motors repairment by the best standards and quality
AGREEMENTS AND WARRANTIES
For all types of services, we sign the agreement and provide a guarantee that’s determined individually depending on the type of work completed. We can also make a supplementary guarantee.
LIST OF WORKS:
Overhaul repair of asynchronous low-voltage electric motors with random winding
Overhaul repair of asynchronous low-voltage electric motors with rigid winding
Overhaul repair of asynchronous low-voltage electric motors with projecting poles
Overhaul repair of asynchronous high-voltage electric motors up to 6 kW and power up to 2 MW
Overhaul repair of asynchronous high-voltage electric motors up to 6 kW and power up to 6 MW
Overhaul repair of low-voltage transformers and winding of distributed polar motors
Repairment of short-circuit windings of the motor armature
Overhaul repair of direct-current motors
Overhaul repair of electric motors of monolith type windings
On coming, the electric motor is sent to the specialists, who will disjoint the motor. While taking it to pieces, sheaves, muff, and other parts of the rotor shafts, lids from end shields are dismounted, and the rotor is taken out from the stator of the electric motor.
Then the comprehensive diagnosis of failures (visual analysis, measurement of special equipment visual analysis). After diagnosis, the specialists start the repair and rewinding.
STAGES OF ELECTRIC MOTOR REPAIR:
- Bearing replacement and sitting areas' reconstruction on the electric motor stator and in end-shields if needed.
- Rewinding of electric motor stator frame (on-machine cutting-off of stator frame, wire removal, stator cleaning and sleeving, wire winding on-machine, and their placing in grooves, winding setting-up, and its bandaging).
- Impregnation of the stator winding with special vanish and further drying in chamber drier.
- Electric motor assembly and check of device winding.
- Electric motor examination according to preset sequence on test panels.
