  • Rogowski coil method of determination of bearing lubrication in dynamoelectric machines
    Patent number: 6300701
    Abstract: It is possible to monitor the performance of a lubrication system performance of a Dynamoelectric Machine (DEM) by observing the electric current flowing in the DEM shaft. Suitable Rogowski coils are mounted around the shaft of the rotor of a DEM just inboard the bearings. The Rogowski coil may be mounted on the shaft to rotate with the shaft, or it may be mounted on said DEM so as to surround the shaft and remain stationary. Shaft current magnitudes may be established for start-up and steady state operating conditions. Any deviation from the steady state shaft current magnitude may be taken as a warning that the DEM bearing lubrication system is malfunctioning.
