Common mode voltage impact on wind turbine main shaft bearing
EPE, 2021Main shaft bearing is a critical component in the wind turbine rotating system. But the bearing voltage, which is generated by the potential differences between the bearing and the main shaft, often causes the downtime of the main shaft bearing.

A Universal Coupled Predictive Model for Motor Bearing Voltage and Multisource Shaft Voltage
IEEE transactions on industrial electronics (1982. Print)This study proposes a universal motor model that accurately predicts both bearing voltages (BVs) and multisource shaft voltages (SVs). The increasingly severe problems of bearing currents (BCs) and electric-erosion faults have made the precise ...
