Bearing voltages and associated bearing currents in electric machines driven by pulsewidth modulation converters with high switching frequencies and high $dv/dt$ can cause premature bearing failures. This article proposes a new modeling approach for the prediction of steady-state and transient bearing voltages based on two-dimensional (2-D ...

Frequency-Dependent Bearing Voltage Model for Squirrel-Cage Induction Motors
IEEE Transactions on Industrial Electronics, 2022This work describes a frequency-dependent bearing voltage model for squirrel-cage induction motors. Previous researches related to bearing voltages commonly considered the bearing voltage ratio (BVR) as a constant. However, it is important to analyze the frequency-dependent behavior of BVR when dealing with systems excited by high switching frequency ...

Study on effect of neutral voltages on shaft voltages causing bearing currents
IECON 2013 - 39th Annual Conference of the IEEE Industrial Electronics Society, 2013This paper investigates that effect of neutral voltage on shaft voltages. The shaft voltages are expected to provide cause of bearing currents. The bearing currents damage bearing in motor. We expect neutral voltages to cause shaft voltages. Thus, we construct circuit of interior motor.
