This paper puts into perspective the state-of-the art knowledge on bearing currents and
diagnosis tools, which rely on shaft voltages and bearing currents phenomena. Today, shaft …

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 …

Remaining useful life (RUL) prediction for condition-based maintenance decision making
plays a key role in prognostics and health management (PHM). Accurately predicting RUL of …

In the last three decades, the study of inverter-induced bearing currents has become a very
important line of research, and hundreds of works related to this theme can be found in the …

Mechanical bearings are an integral part of industry, and are used in various places in order
to reduce friction between two interacting surfaces and are used to transmit power and …

An 1.1 kW-induction machine and an 1.5 kW-permanent magnet synchronous machine
(PMSM) are investigated, measuring the common-mode bearing currents in dependence of …

The authors deal with the use of electrostatic shielding to mitigate the electric discharge
machining (EDM) currents on the induction machine bearings. Employing 2D and 3D …

High frequency bearing currents are a parasitic phenomenon that affects inverter-fed
induction machines, causing damage and wear to the mechanical bearings, which might …

The knowledge of the system behavior of modern drive trains is essential for more and more
integrated drive systems with variable-speed operation. While state-of-the-art inverters have …
