An electric motor having a cooling channel which leads through an interior space surrounded by a stator and a housing comprises a first housing component, which forms a base opposite a first axial end of the stator, and a second housing component opposite a second axial end of the stator as a cover, and the first housing component has an inlet and an outlet for cooling liquid and an inner part which projects into the stator. The inner part forms a sleeve, in which the first end of the shaft is arranged, and the inner part also forms an annular space which is arranged between the stator and the sleeve, wherein a cooling channel section for cooling the stator extends in this annular space, and wherein at least one bearing of the shaft is arranged in the sleeve.
