DC electric motor repair
Repair procedure is a dynamical process that demands all round knowledge of how DC electric motor functionsand how its parts contribute to its functionality
Malfunction cause identification
On arrival, the DC electric motor undergoes a thorough visual inspection. We check the possibility of any materials break-in. After that decision is made whether we can run other tests before motor disassembly.
Braking unit test
If the DC electric motor has a brake unit installed we check it’s functioning and stated torque.
Stator and rotor electric tests and coil rewind
After all tests stated above we check the stator and rotor winding functioning by use of a specialized winding tester. If the motor coil is damaged we take care of the coil rewind. .
Rotor balancing
If the rotor has sustained damage and the vibrations are present we take care of the rotor repair and dynamic balancing.
Housing sandblasting and detail cleaning of parts
We clean DC every electric motor housing with the use of a sandblasting machine or powerwash. For internal parts cleaning in the repair process we use specialized cleaning fluids and tools.
Tolerance measurements of drive axis and bearing seats
After sandblasting and cleaning of DC electric motor we measure the tolerances of bearing seats on drive end and non drive end flanges and axis bearing positions.
Impregnation of winding and rotor
We impregnate DC electric motor stator and rotor winding with thixotropic impregnation agent in order to achieve longer service life.
Bearing and seal replacement
In every DC electric motor repair process we replace all bearings and seals. We install only quality bearings of world renowned manufacturers.
Power and signal connectors test
If the power or signal connectors are damaged or malfunctioning we make sure to replace it with new OEM parts.

DC Electric motor test run
We run every DC electric motor before returning it to the customer production facility to make sure it runs according to factory specifications.
New painting of motor housing
Every electric motor we get in our repair shop is repainted in OEM RAL after all the repairs and tests are done in order to make it function and look as good as new.
New ID and warning labels fabrication
We equip every DC electric motor with new ID and warning labels to make sure safety and identification standards are achieved
Service report
During the DC electric motor repair process we document all gathered test data and measurements with the purpose of giving our clients as much information as possible about the state of their motor.
