We repair, and we do revisions of traction motors and DC's auxiliary machinery. To repairs we use the highest quality materials and components. Qualifications of the staff and a broad technical knowledge guarantee a high level of service. We also have years of experience in the industry.

The scope of repairs includes:

  • measurement of winding resistance and insulation condition
  • measurement of the absorption coefficient
  • measurement of voltage drops on the winding rotor
  • bearing replacement
  • rotor’s rewinding
  • stator’s rewinding
  • dynamic balancing of rotors
  • replacement of commutators
  • TIG welding of commutators
  • soldering of commutators
  • machining of commutators
  • vacuum-pressure impregnation VPI
  • testing at the test station
