Abstract
An electrical machine includes a rotor that is rotatable about a rotation axis, and includes a stator having electrically conductive stator windings. The machine includes a cooling channel through for cooling the stator windings. The stator has teeth extending arranged at a distance from one another along a circumferential direction of the rotor, the stator teeth protruding inwardly and carrying the stator windings. An interspace is formed between two stator teeth which are adjacent in the circumferential direction. An interspace is arranged in an insulation body having outer walls composed of a plastic, which delimit a body interior, in which a winding zone and a channel zone are provided. A stator winding is arranged in the at least one winding zone of the insulation body and a cooling channel for a is arranged in the at least one channel zone of the insulation body.
