An electric motor vehicle traction motor has a motor housing, a liquid-cooled motor stator and a dry running internal motor rotor which is separated fluidically from the motor stator. The motor stator is formed by a stator body with radial stator slots and a plurality of stator coils. The axial phase windings are arranged in the stator slots, and the winding heads of protrude axially out of the stator slots. A slot potted body is made from a potting material and by way of which the stator coil axial phase windings are potted into the stator slots in a fluid-tight manner. The stator coil winding heads are of potting-free configuration and protrude in each case directly into a fluid-tight cooling space. As a result of the omission of a separate split cage, a small air gap is realized and manufacturing costs are reduced.
