For a shaft of an electric motor with a runout sensing area, an electrical runout value for the runout sensing area is determined, the shaft is rotated and the runout sensing area of the shaft is heated sufficient to reduce the electrical runout value.

Systems for reducing slow roll

Certain exemplary embodiments comprise a system for cooling bearing of a shaft of a motor, comprising: an oil sump adapted to collect oil that contacts a bearing enclosed within the sump; and a heat exchanger physically separated from the sump and the bearing, the heat exchanger adapted to be in fluid communication with the sump and the bearing.

Method for maintaining a vertical motor thrust bearing

A system for cooling a bearing of a shaft of a motor comprises an oil sump adapted to collect oil that contacts a bearing enclosed within the sump; and a heat exchanger physically separated from the sump and the bearing, the heat exchanger adapted to be in fluid communication with the sump and the bearing.

System for maintaining a vertical motor thrust bearing

Certain exemplary embodiments comprise a method that can comprise, via a device that originates sub-harmonic vibrations, applying a vibration treatment, to a rotor of an electric motor for a predetermined time period. The rotor can be thermally sensitive. The vibration treatment can be adapted to reduce internal stresses in the rotor, thereby reducing a vibration level of the rotor.
