Abstract
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.
