Electric damper for damping the relative movement between a first and a second mass, comprising a generator driven by the mass movement having a fixed stator and a rotor rotatable relatively thereto, and a transmission coupled with the generator, wherein by means of the mass movement at least one first gear element connected directly with a lever element movable by means of the mass movement is set in a rotary movement, which first gear element is directly or indirectly translationally movably coupled with at least one further gear element, wherein the second gear element is movably coupled with the rotor of the generator such that a rotary movement of the rotor relative to the stator results, wherein the gear designed as transmission gear either - is designed as a planetary gearing having an annular gear, at least two planetary gears engaging with the annular gear and a sun gear engaging with the planetary gears, wherein the annular gear forms the first gear element and the sun gear movingly coupled with the rotor forms the second gear element, or - is designed as a strain wave gearing having a ring- or cylinder-shaped flexible unit with an external toothing, a rigid unit forming the first gear element having an internal toothing engaging with the external toothing of the flexible unit and an oval rotary element, disposed in the interior of the flexible unit, interacting with the flexible unit and deforming the latter, movingly coupled with the rotor and forming the second gear element, or - is designed as a cycloid gearing, having a ring- or cylinder-shaped unit, which is connected with an edge-sided tooth-like profiled cam plate, which for its part engages with a tooth-like profiled fixed housing part, wherein the ring-or cylinder-shaped unit forms the first gear element and at the cam plate, preferably in a bore, is disposed the second gear element which engages into the first gear element and is movably coupled with the rotor, - characterised in that the generator has a hollow cylindrical housing, wherein a first housing section accommodates the rotor and the stator and a second housing section adjoins the transmission, and that an annular section, serving to connect the transmission to the housing, at least sectionally enclosing the housing axially and at least sectionally bearing upon the housing outer surface, is assigned to the transmission. - is designed as a planetary gearing having an annular gear, at least two planetary gears engaging with the annular gear and a sun gear engaging with the planetary gears, wherein the annular gear forms the first gear element and the sun gear movingly coupled with the rotor forms the second gear element, or - is designed as a strain wave gearing having a ring- or cylinder-shaped flexible unit with an external toothing, a rigid unit forming the first gear element having an internal toothing engaging with the external toothing of the flexible unit and an oval rotary element, disposed in the interior of the flexible unit, interacting with the flexible unit and deforming the latter, movingly coupled with the rotor and forming the second gear element, or - is designed as a cycloid gearing, having a ring- or cylinder-shaped unit, which is connected with an edge-sided tooth-like profiled cam plate, which for its part engages with a tooth-like profiled fixed housing part, wherein the ring-or cylinder-shaped unit forms the first gear element and at the cam plate, preferably in a bore, is disposed the second gear element which engages into the first gear element and is movably coupled with the rotor, - characterised in that the generator has a hollow cylindrical housing, wherein a first housing section accommodates the rotor and the stator and a second housing section adjoins the transmission, and that an annular section, serving to connect the transmission to the housing, at least sectionally enclosing the housing axially and at least sectionally bearing upon the housing outer surface, is assigned to the transmission.
