SIA "Rinas Baltic" is one of the few companies in the Baltic region that operates in the field of supply and maintenance of electric drives, DC motors, and slip ring motors. Due to a significant increase of new equipment lead time, we invite you to consider the possibility of repairing your equipment in our company.

We repair DC motors and large electric motors from the following manufacturers: ABB, Siemens, Faurndau, Baumueller, Lenze, Sicme Motori, Vascat, Brusatori, EW Hof, Helmke, Menzel, Cear, Comer, T-T Electric, Leroy Somer, Ansaldo, Brusatori...

If you need prompt delivery of equipment until the repair is completed, we are ready to offer you electric motors up to 300 kW and electric drives up to 1200A from our stock. We can supply carbon brushes, brush holders, tachogenerators, encoders, electric control drives.

Our clients are industrial enterprises from Latvia, Lithuania, Estonia and Poland. We have already repaired electric motors for extruders, mixers, printing machines, printers, granulates, cranes, presses, woodworking machines, cardboard machines, molding machines, rubber dispensers, cutters.

This is how equipment looks like when we receive it from our customer

This is the result of our work

We work as follows:

  • Picking up equipment to perform diagnostic work without disassembling the electric motor;
  • Coordination of a preliminary technical and commercial proposal, discussion of possible risks that can occur after disassembling the electric motor;
  • Disassembling the electric motor, identifying hidden defects and damage, agreeing on the final cost of repairs.
  • Carrying out repair work.

Advantages of cooperation with us:

  • Reducing equipment downtime;
  • The repair works period takes 6-8 working weeks;
  • The cost of works is not more than 30-50% of the cost of new equipment installation;
  • Warranty for services from 6 to 12 months;
