Abstract
In a frame having integrated cooling for an electric drive, coolant flows through a width of the frame in an inverse manner. The frame has roughly the form of a cylinder sleeve having a diameter and an axial width, whose outer surface is provided with cooling ducts. A first bundle of cooling ducts, connected in parallel, guides the coolant from a coolant intake around substantially the entire circumference of the frame. A second bundle of cooling ducts, connected in parallel, guides the coolant around substantially the entire circumference of the frame, back to a coolant outlet (8).
