Abstract
An electric machine () has a housing () in which a stator () and a rotatable rotor () are arranged. The stator () is of hollow-cylindrical design and is arranged in a stator chamber () of the housing (). The rotor () is arranged radially inside the stator () in a rotor chamber (). An air gap () is provided between the rotor () and the stator () to permit rotation of the rotor () relative to the stator (). The stator chamber () is delimited radially on the inside by a cylindrical wall () that is sealed with respect to the housing () by at least one sealing element (). The housing () has at least one axially projecting protrusion () that forms an axial end face () and a radially outwardly facing circumferential shoulder () that supports the sealing element ().
