Repair of the 2PN-226 Electric Motor

Repairing the 2PN-226 electric motor, installed on the TGM4 locomotive, is an essential procedure to maintain the reliable operation of the locomotive

This motor is used to drive auxiliary mechanisms and systems of the locomotive.

Main Stages of Repairing the 2PN-226 Electric Motor:

1. Dismantling the Electric Motor:

• The 2PN-226 electric motor is dismantled from the locomotive following all safety measures.

• Before dismantling, it is necessary to disconnect all electrical and mechanical connections.

2. Cleaning and Initial Diagnostics:

• All components of the motor are thoroughly cleaned of dirt and deposits.

• Initial diagnostics are carried out to identify visible damage and wear.

3. Disassembling the Motor:

• The motor is disassembled into separate units and parts for detailed inspection.

• Particular attention is paid to the condition of the windings, bearings, brushes, and commutator.

4. Assessing the Condition of Components:

• Measurements of all critical parameters of the parts are carried out (winding resistance, brush wear, condition of the commutator and bearings).

• Components that require replacement or repair are identified.

5. Repair and Replacement of Parts:

• Worn or damaged parts are replaced with new or refurbished ones.

• The windings are repaired, brushes and bearings are replaced, and the commutator is cleaned and polished.

6. Assembling the Motor:

• The motor is reassembled following all technical requirements and standards.

• All connections and assemblies are checked for compliance with standards.

7. Bench Testing:

• The electric motor undergoes bench tests to verify its operability and compliance with operational characteristics.

• The motor’s performance parameters, such as power, current, and vibration, are checked.

8. Installation on the Locomotive:

• The repaired motor is reinstalled on the locomotive.

• All necessary electrical and mechanical connections are reconnected.

9. Operational Testing:

• After installation, the electric motor is tested under working conditions on the locomotive.

• The motor’s performance parameters are checked under real operating conditions.
