A Collocated Eddy-Current Displacement Sensor for Magnetic Bearings [PDF]
한국정밀공학회지, 2022 Magnetic bearings use electromagnetic force to support the rotating shaft without any mechanical contact and actively control shaft vibration; hence, there is no mechanical friction and wear due to contact during the operation, and it has a semi ...

The Use of Bearing Currents and Vibrations in Lifetime Estimation of Bearings
IEEE Transactions on Industrial Informatics, 2017 Electric discharge machining current causes a significant amount of damage to bearings, producing pits in the rotating elements of the bearing, and ultimately leading to bearing failure. Although this relationship is well known and studied, little work has been done to relate bearing current discharge events to bearing vibrations for bearing failure ...

Current-carrying friction in carbon coated ball bearing
Friction, 2023 In this work, we proposed a method for coating the whole surfaces of bearing balls uniformly by carbon film with a rotatable ball clamp. We studied the carbon/carbon friction with a self-designed current-carrying ball bearing friction test system.
