Abstract
An electric machine, in particular an axial flux machine, including a rotor mounted in a dry chamber rotatable relative to a stator, the rotor having a rotor shaft with at least one first disk-shaped rotor member which is non-slidably arranged on the rotor shaft for conjoint rotation therewith, the stator having a first annular disk-shaped stator member and a second annular disk-shaped stator member which are arranged coaxially to one another and coaxially to the rotor shaft and are axially spaced apart from one another, the rotor being arranged in the space therebetween. 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 first stator winding has first winding ends which protrude from the first stator member and which extend in the axial direction radially above the stator member, and the second stator winding has second winding ends which protrude from the second stator member and which extend in the axial direction radially above the first stator member and the second stator member.
