An electric machine includes a rotor, a stator housing and a winding assembly surrounding the rotor. The winding assembly is arranged in the stator housing and has an axially extending effective region in which the winding assembly is set up to interact electrodynamically with the rotor. The stator housing has a peripheral opening slot on the side facing the rotor. The opening slot corresponds in its axial extent to the axial extent of the effective region of the winding assembly and in which an electrically non-conductive can of the electric machine is inserted. The can is sealed off with the stator housing in such a manner that the winding assembly is hermetically separated from the rotor. The can extends axially only on the effective region of the winding assembly.
