Abstract

Running gear for electric rolling stock has a traction motor 17 whose rotor shaft is arranged to have at least a portion at which the shaft bearing 15 makes contact made of an electrically insulating material 19. The electrically insulating material prevents erosion of the bearing by the electric current supplied to the axles 3. <IMAGE>
