1. An electric machine, comprising:
a stator;
a rotor rotatable relative to the stator about a rotational axis which defines an axial direction;
a housing at least partially surrounding a housing interior, the housing including a plurality of housing parts, the plurality of housing parts including a first housing part and a second housing part which bound the housing interior and on which the rotor is rotatably mounted via a bearing device;
at least one heat transmission body arranged along the axial direction between at least one housing part of the plurality of housing parts and the rotor, the at least one heat transmission body and the at least one housing part bounding a coolant space through which a coolant is flowable;
wherein at least one of the plurality of housing parts includes an attachment section to which the at least one heat transmission body is attached;
wherein the bearing device is disposed on the attachment section;
wherein the at least one heat transmission body includes a cooling plate extending transversely to the axial direction; and
wherein the cooling plate has an axial wall thickness of 3 mm or less.
