Abstract

Arrangement for cooling a housing (Ia, Ib) with an inlet (11) and an outlet (12) and enclosing in its volume (10) a stator comprising stator winding (2) and stator iron (3) of an electric motor, which drives a rotor (7) with its shaft (4). The invention is characterized in that the volume (10) is arranged separated from the rotatable parts (7, 4) in a sealed manner.
