Abstract: An electric machine includes a rotor surrounded by a stator. An external jacket surrounds the stator and extends between front and rear end parts, thereby delimiting an inner region which accommodates the rotor, and an outer region radially surrounding the inner region. The inner and outer regions communicate with one another via recesses to enable air to flow out of the inner region and into the outer region and from there to flow back into the inner region. Front and rear closing elements are attached to the front and rear end parts on their side facing away from the external jacket, thereby enclosing a front cavity and a rear cavity. Axial tubes are fastened in the front and rear end parts such that the axial tubes extend from the front end part across the outer region to the rear end part and open in the front and rear cavities.
