An electric machine has a rotor on a rotor shaft. The rotor shaft is supported on bearings such that the rotor and the rotor shaft are rotatable around an axis of rotation. The rotor is surrounded radially on the outside by a stator, the stator by a casing. Covering elements are arranged at the axial ends of the rotor and stator, by which the rotor and the stator are enclosed with respect to the environment of the electric machine. One covering element is surrounded radially on the outside, and axially on the side facing away from the rotor and stator there, by an air guide element, the other covering element by an inner ring element. First and second cooling channels running axially are arranged in the casing or between the casing and stator. Rotor channels running axially are arranged in the rotor shaft and/or in the rotor.
