In order to increase the operational safety of an actuator () including an electric motor () and a transmission, preferably a non-self-locking transmission (), a braking device is provided which allows the controlled, self-actuating displacement, by a retarding brake (), of an actuating element connected to the actuator () via the transmission (). The actuating element can be held in a fixed position by an additional holding device (), even if the electric motor () fails. The actuator can be used to drive heavy sluice gates, in the event of a power failure, in a controlled free-fall operation at a constant rate of fall, or to hold them in a defined position. The holding device and the retarding brake can be combined in a common housing () to form a braking module () which can be designed to be used modularly with existing motor actuators and transmissions.
