An electrical machine for driving a motor vehicle includes a housing, a stator, which is fixedly accommodated in the housing, and a rotor, which is mounted rotatably relative to the stator. The stator has a laminated core composed of a plurality of punched lamination segments and has a wire winding region connected to the laminated core. Each lamination segment has, on its radial exterior, at least one radial recess also created by means of the punching production. A coolant guide channel is delimited directly by an outer periphery of the laminated core. A recess of a first lamination segment is spaced apart, along the outer periphery, from a recess of a second lamination segment directly abutting the first lamination segment in such a way that the recess of the first lamination segment is at least partly axially covered by an end face of the second lamination segment.
