The Novosibirsk Electric Locomotive Repair Plant (NERZ) has commissioned a machine for repairing the commutators of traction-motor armatures used in Sinara 2ES6 electric locomotives. The entire component-processing cycle can now be completed on a single machine.
Previously, the part had to be moved between multiple machines, with some operations performed manually. The new equipment handles:

The machine-vision system is designed for accuracy of up to 0.001 mm. According to the Sinara — Transport Machines holding, it distinguishes between copper and mica, helping maintain the component’s geometry within specified tolerances.

NERZ has also adapted the equipment to process armatures for 4PNZh200 electric motors installed in EP2K electric locomotives. That work was previously done by hand. The updated process is expected to remove unnecessary operations and shorten repair times.
The 2ES6 Sinara has been produced at Ural Locomotives since 2006, with more than 1,500 units built. A dedicated repair base reduces the need to transport components between facilities as the fleet grows.
