Abstract

An electrical machine for a vehicle includes a rotor, which can be rotated about an axis of rotation, by which an axial direction of the electrical machine is defined, a stator with stator windings; and a cooling channel, or a plurality of cooling channels, through which a coolant flows. The stator has stator teeth, which extend along the axial direction and are spaced apart from each other along a circumferential direction and which bear the stator windings. At least one stator winding is embedded in an electrically insulating plastic for thermal coupling, the electrically insulating plastic is arranged, together with the at least one stator winding, in an intermediate space, which is formed between two stator teeth adjacent in the circumferential direction, and the electrically insulating plastic is formed by a first plastic mass of a first plastic material and a second plastic mass of a second plastic material.
