An electric machine includes a housing which accommodates a stator and a rotor rotationally supported about an axis of rotation, and has a front/rear air inlet opening on a top face and an air outlet opening therebetween. A front/rear air conveying element draws into the air inlet openings air which is discharged from the air outlet opening during operation. A cooler is mounted on the top face of the housing, covering the air inlet openings and the air outlet opening in a hood-like manner, such that discharged air is fed back to the air inlet openings. The cooler has a front/rear partition arranged between the air outlet opening and the corresponding air inlet opening and extending upward from the top face. Air guiding elements are arranged in the housing and/or in the cooler for feeding discharged air at least partially to the respective other air inlet opening.

Certain exemplary embodiments can comprise a system, which can comprise an electric motor cooling fan. The electric motor cooling fan can be driven by an auxiliary motor distinct from an electric motor adapted to be cooled by the electric motor cooling fan. The system can comprise a motor enclosure of the electric motor. The motor enclosure can be configured in a predetermined ventilation pattern.
