Avoid Bogie Bearing Failure of IGBT Inverter Fed EMUs and Locomotives
Three current paths are proposed, and theoretical analysis and laboratory tests are carried out to investigate the root causes of bearing failure in IGBT inverter-fed locomotives and EMUs. The three types of current paths that run through the drive unit bearings and axle box bearings used on EMUs an...
