Abstract
An electric machine for an electric drive train in a motor vehicle including a rotor that is rotatably mounted relative to a stator, the rotor having a rotor shaft with at least one first rotor member which is non-slidably arranged on the rotor shaft for conjoint rotation therewith, the stator having a first stator member and a second stator member which are spaced apart from one another; the first stator member has a first stator winding, and the second stator member has a second stator winding, the first stator winding being arranged within a first hydraulic chamber, and the second stator winding being arranged within a second hydraulic chamber, at least part of the stator windings being able to come into contact with a hydraulic fluid in the hydraulic chambers. The electric machine further including a hydraulic connection element which hydraulically connects the first hydraulic chamber to the second hydraulic chamber; at least one electric conductor of the first stator winding and/or of the second stator winding is arranged within the hydraulic connection element.
