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;
- Repair work is carried out at our factory that produces DC electric motors;
- Guarantee of compliance with repair technologies;
List of services performed:
- Replacement of electric motor armature windings, vacuum impregnation and drying of windings;
- Replacement of main poles and additional poles (repair of magnetic system);
- Repair of shaft mechanical damage;
- Repair, production of bearing shields and flanges;
- Inspection of commutators, replacement or repair of commutators, slip rings;
- Replacement of brushes, brush holders, adjustment of mechanisms;
- Checking and repairing the existing electric motor cooling system, repairing fan balancing;
- Electric motor rotor balancing, assembly, vibration diagnostics.
In process of repairing an electric motor, we carry out the following tests:
- Winding resistance measurement;
- Measurement of insulation resistance relative to the housing and between windings;
- Calculation of absorption coefficient;
- Testing the insulation of windings, testing the interturn insulation of the armature winding for electrical strength, testing mechanical strength;
- Checking the performance of the electric motor with no load, measuring current characteristics;
- Checking the performance of the electric motor under load, measuring current characteristics.
- Measurement of vibrations, monitoring the thermal state of critical components of the electric motor.
