On a New Type of Inverter-Induced Bearing Current in Large Drives with Oil-Lubricated Bearings
2008 IEEE Industry Applications Society Annual Meeting, 2008We report on a new type of inverter-induced bearing current that can occur with large inverter-based drive systems with one journal bearing. This current is a variation of the "high-frequency circulating" bearing current type which has been described by different authors over the last years.

Experimental Investigation of an Eddy-Current Bearing
1989An AC-electromagnetic bearing based on eddy-current repulsion has been built and tested. The bearing was found to be inherently stable and able to provide support in five degrees of freedom, i.e. a short rotor was fully supported by a single bearing without any feedback control. However, with the current design configuration, the load carrying capacity
