A bearing assembly for a motor shaft of an electric motor having a stator. The stator is formed by a stator core having a plurality of stator laminations, which are stacked one on the other. The stator core has a first outer partial stator core, a second outer partial stator core, and a central partial stator core. The central partial stator core is arranged between the two outer partial stator cores. A continuous opening is arranged in each of the partial stator cores, in which openings bearings for supporting the motor shaft are arranged and the motor shaft is arranged. A diameter of the opening of the central partial stator core is smaller than a diameter of the opening of the outer partial stator cores such that a diameter transition from the central partial stator core to an outer partial stator core forms an axial stop for a bearing.
