Abstract

An electrical machine may include a rotor rotatable about an axis of rotation, by way of which an axial direction of the electrical machine may be defined, a stator having electrically conductive stator windings, and at least one cooling channel through which a coolant may be flowable for cooling the stator windings. The stator may have stator teeth extending along the axial direction, arranged spaced apart from another along a circumferential direction of the rotor, and bearing the stator windings. The at least one cooling channel and at least one stator winding may be arranged in at least one intermediate space formed between two stator teeth adjacent in the circumferential direction. A plastic for transferring heat from the at least one stator winding to the at least one cooling channel may be arranged in the at least one intermediate space.
