ELECTRIC MACHINE HAVING A ROTOR SHAFT BEARING A ROTOR FOR A VEHICLE DRIVE TRAIN

摘要

The invention describes an electric machine (1) having a rotor shaft (3) bearing a rotor (2) for a vehicle drive train. The rotor shaft (3) is rotatably mounted in regions (6, 7) fixed to the housing, via two bearing devices (4, 5), between which the rotor (2) is arranged on the rotor shaft (3). At least one of the bearing devices (5) is provided in a region of the diameter (10) of the rotor shaft (3) which is reduced with respect to a region of the diameter (8) of the rotor shaft (3) in which the rotor (2) is arranged.
