In a cooled housing for the stator of a direct drive, cooling ducts extend on an outer peripheral surface of the housing, the cooling ducts being sealed by an annular cover extending around the peripheral surface. The cover includes openings as an inlet and outlet for a cooling medium, and the cover is arranged such that sections of the peripheral surface of the housing remain free.
