1. An electric actuator having an electric motor comprising a rotor which is arranged such that it rotates about an axis of rotation in a stator housing having an axial installation length, wherein the stator housing is arranged with an axial end in a controller housing and is fastened within the controller housing,
wherein the stator housing comprises a stator pot including a flange region and a pot base, wherein the pot base is positioned on a side facing away from the flange region, the stator housing is arranged in the controller housing at the axial end and in a transmission housing at an opposite axial end, the stator housing is arranged entirely within a cavity which is delimited by a recess of the controller housing and a recess of the transmission housing such that the stator pot is encapsulated within the cavity, wherein the electric actuator further comprises a first bearing for a rotor shaft of the rotor, the first bearing being positioned in the pot base.
