Induction Motor Bearing Currents - Causes and Damages

2021 28th International Workshop on Electric Drives: Improving Reliability of Electric Drives (IWED), 2021
Bearing damages make the biggest proportion of faults affecting AC electrical motors. There are various subdivisions of the bearing faults but one of them is the induced bearing and shaft currents in the machines. These currents cannot be fully avoided, yet with the development of power electronic control of the machines, the number of machines ...

Bearing wear caused by converter-induced bearing currents

IECON 2010 - 36th Annual Conference on IEEE Industrial Electronics Society, 2010
The basic interrelationships that are required to investigate the cross-system subject of “bearing currents in converter operation”, are discussed in this paper. In order to obtain an integrated overview of the situation, it is decisive that the main points of the investigation are not discussed individually, but must be considered from an overall ...

Bearing currents in converter operation

The XIX International Conference on Electrical Machines - ICEM 2010, 2010
The basic inter-relationships, which are required to investigate the cross-system subject of “bearing currents in converter operation”, are discussed in this paper. In order to obtain an integrated overview of the situation, it is decisive that the main points of investigation that are discussed are combined and viewed holistically.

Investigation of influence of bearing load and bearing temperature on EDM bearing currents

2010 IEEE Energy Conversion Congress and Exposition, 2010
To detect the worst case and the best case of the bearing operating conditions concerning the magnitude of the high frequency discharge bearing currents (“EDM currents”) and the frequency of electric discharges in the bearings of the small power inverter-fed AC motors, systematic investigations have been performed for three, 4-pole, 1.5 kW squirrel ...
