Abstract

A transversal flux machine having a stator and an external rotor disposed about the stator, the stator comprising two axial end faces, having an inner core of the stator, having a cooling path disposed radially within the inner core, wherein a cooling path either a) protrudes out of the transversal flux machine on the axial end face of the stator, said transversal flux machine facing away from an inlet side, or b) the cooling path protrudes out of the transversal flux machine on the axial end face of the stator, said transversal flux machine facing away from the inlet side, the cooling path running between the inlet and the outlet in an intermediate space between the stator and the external rotor of the stator facing the inlet side, the cooling path between the inlet and the outlet running in an intermediate space between the stator and the external rotor.
