The invention relates to an electric disk motor comprising: a rotor (10), which has an element (105) to be moved； and a stator (10), wherein the stator is arranged with respect to the rotor (20) in such a way that a motor gap (30) is present between the rotor and the stator, wherein the rotor (10) has a cut-out (40), in which the stator (20) is arranged, wherein the rotor (10) is arranged in a first region (50) having a first pressure, wherein the stator (20) is arranged in a second region (60) having a second pressure, wherein the second pressure differs from the first pressure, and wherein an encapsulating material (70) is arranged in the motor gap (30), by means of which encapsulating material the first region (50) is separated from the second region (60).
