An electric machine has a housing, a rotor shaft mounted in the housing, a rotor laminate stack arranged on the rotor shaft and having axial cooling channels and radial cooling channels, and a stator laminate stack having radial cooling channels which are open radially inwards and radially outwards and interact with the radial cooling channels of the rotor laminate stack. The housing has a lateral surface to delimit the housing interior in a radial direction and radial dividers arranged between end windings of the stator winding and the axial ribs, when viewed in the radial direction, and are spaced in the radial direction from the lateral surface delimiting the housing interior and forming tangential cooling air channels for the cooling air.
