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 ...

Bearing currents and their relationship to PWM drives

IEEE Transactions on Power Electronics, 1997
This paper examines AC motor shaft voltages and the resulting bearing currents when operated under pulse width modulation (PWM) voltage source inverters. The paper reviews the mechanical and electrical characteristics of the bearings and motor in relation to shaft voltages and bearing currents.
