Overhaul inspection

The overhaul inspection is connected with the bearing replacement (motors with wheel bearings), rotor and stator windings control.
The overhaul inspection is obligatory after 20000 – 25000 operating hours (depending on the number of motor starts and the operating load).

If a motor does not operate, and it is located in the operating zone of other motors or plants, the overhaul inspection must be performed every three years to ensure reliability.
