Abstract
An electric machine includes a housing, a stator rigidly arranged on the housing, a rotor rotatably supported on the housing, and a canned tube. The stator and rotor bound a radial gap. The canned tube fluid-tightly abuts the housing such that the canned tube fluid-tightly separates a wet space through which a coolant can flow from a dry space. The stator and rotor are arranged in the wet and dry spaces, respectively. The canned tube on an outer peripheral surface and/or the stator on an inner peripheral surface includes an elastically deformable sealing element. The sealing element is elastically deformed in a finally mounted state of the canned tube between the outer peripheral surface of the canned tube and the inner peripheral surface of the stator such that a gap between the outer peripheral surface and the inner peripheral surface of the stator is sealed.
