Repair of the P-41 Electric Motor

The P-41 electric motor is used in TGМ6 locomotives to drive auxiliary equipment

This is an asynchronous motor designed to operate under increased mechanical and thermal loads.

It is built according to the AIR classification, offers protection against environmental impacts, and is known for its reliability in operation.

The main specifications of the P-41 electric motor include a rated power of 37 kW, a rated voltage of 380 V, a rotational speed of 1500 RPM, and air cooling.

Key Steps in Repairing the P-41 Electric Motor:

The repair process for the P-41 electric motor typically starts with diagnostics, which involves assessing the motor’s condition using various testing methods such as insulation resistance measurement, winding inspection, and load performance analysis.

The motor is then removed from the locomotive and disassembled to check the condition of internal components like bearings, windings, and the rotor.

Winding repair may include replacing or restoring damaged windings to ensure stable motor operation.

Worn parts such as bearings and the commutator are also replaced.

After the repair, the motor is reassembled and tested on a specialized test stand to verify all its parameters and functionality.

The quality of the repair is critical to ensuring the reliable operation of the locomotive and preventing further breakdowns.
