| Abstract: | The current path through drive unit bearings and axle box bearings of IGBT Inverter-fed electric locomotives is investigated and analyzed. Especially, the EDM current inducing the electric erosion failure is analyzed. The proofs to identify the electric erosion and the corresponding solutions to prevent the failure are proposed. |
