Abstract: Electrical machines are widely used in conjunction with power converters which use high frequency witching devices to modulate machine terminal voltages in order to control the machine speed or torque. The high frequency switching produced by the power converter can cause high frequency parasitic currents flowing through the machine bearings, leading to deterioration of the lubrication film and surface damage to the rolling parts of the bearings. This training session will explain the high frequency bearing current mechanism, review of bearing current modelling approaches, review of bearing current mitigation techniques, and our research activities on bearing currents.
This training session is open to all members of staff at our hub partners.
The session is being delivered by Dr Xiao Chen (University of Sheffield) and Dr Daniele De Gaetano (AMRC).
