Groundeded Electrodes Approach to Reduce Bearing Currents: Robustness Analysis for Open-Slots Machines
Proceedings of the IEEE International Symposium on Industrial Electronics (IEEE, 19.07.2024)Bearing currents, a critical concern in modern electric motors powered by frequency converters, lead to overheating, increased vibration, and accelerated wear. The Grounded Electrodes Approach (GEA) involves placing thin ... -
Mitigating noncirculating bearing currents by a correct stator magnetic circuit and winding design
(IEEE, 06.04.2020)Different mechanisms by which bearing currents flow inside the electrical machine are well studied. In contrast, investigation and development of different techniques to mitigate these currents remain a field for improvement, ... -
Mitigation of inverter-induced noncirculating bearing currents by introducing grounded electrodes into stator slot openings
(IEEE, 23.12.2020)Modern converter-supplied AC motors are exposed to bearing currents. Despite extensive research and development, the industry still does not have a final solution with acceptable cost and high efficiency. This paper focuses ... -
On the application of extended grounded slot electrodes to reduce non-circulating bearing currents
(IEEE, 11.05.2022)Power-electronic-Inverterconverter-induced motor bearing currents are a widespread problem in the field of electrical drives. Parasitic capacitances between the electrical machines parts provide a path for leakage currents, ... -
Robustness of Grounded-Electrode Approach to Mitigate Bearing Currents in Electric Machines with Semi-Closed Slots
Proceedings (International Conference on Electrical Machines) (IEEE, 09.10.2024)Electric motors are integral to diverse industrial applications, yet their reliability is hampered by bearing currents-a parasitic phenomenon causing excess wear and damage to the machine's bearings. This paper addresses ... -
Slot Wedges with Integrated Grounded Electrodes for Suppression of Inverter-Induced Bearing Currents
Proceedings (International Conference on Electrical Machines) (IEEE, 09.10.2024)Reliable operation of electric motors is vital for industrial applications. Yet bearing currents pose significant threats to their efficiency and longevity. Parasitic electrical currents, particularly prevalent in modern ...
